I don't recommend this food at work. It has corn, wheat and soy. Not only that but Hills uses Animal Fat for a preservative. I did call and ask what kind of animal they used and the person told me either chicken or pork. So then how come they can't put that on the bag? I don't know. There have been a lot of customers that complain that their dog(s) poop more or they are hungry again after being fed. In reality, you need to feed more because of the grains. I went to a SD seminar last summer and the lady said that if you don't feed your dog or cat SD then you might as well buy a shovel and a coffin because you are killing it! I will not sell this to a customer.

I started feeding my Chihuahua SD puppy when he was 9wks old. The breeder had started him on Eukanuba but he was pooping 10-15 time a day so I switched him. There seemed to be a large improvement with Science Diet. He wasn't going as much and he seemed to like it just fine. However, he still wasn't very healthy. His skin was red and flaky and he was loosing hair. I was told by my vet that this was normal because he is a blue chihuahua and they tend to have skin conditions. I thought there was nothing I could do about it.
Then when I was visiting my sister months later, I spotted a Holistic Pet Center. I dropped in to see if perhaps they had something topical i could apply to my chi's skin to help it. They did have something topical but they also insisted that his diet was the main problem for him. I was really resistant but grudgingly I purchased a bag of Azmira Holistic dog food. With in a weeks of switching from SD to Azmira his skin started looking less red and flaky and in about a month I noticed that his hair was growing back! He is happy and healthy now. Also Azmira is CHEAPER than Science Diet (but hard to find). If your dog is healthy on science diet, great. But if not, try a holistic food like Azmira and I'd be really surprised if you didn't see improvements.

I gave it 4 stars because I know its ingredients are not really that good, but nonetheless my dogs love it and are healthy when on it.

SD is not the best food, but it is not horrible, either. At the end of the day, it's the dogs' opinions (expressed in the form of their health conditions) that matter. If your dogs aren't in good heath when on SD, then feed them something else. But if your dogs are in good health when on SD, like my dogs are, then there's nothing wrong feeding them SD. I'm so tired of hearing people accusing SD users to be bad pet owners. I choose SD and I am not a bad pet owners. I take my dogs exercises regularly and give them a lot of love and attention. They are healthy and happy dogs.

I've tried several good brands (Wellness, Blue, Nutro, Natural Balance...) but somehow my dog just didn't do well when she's on these better brands. She had loose stool and her itching and paw-chewing problems got really bad, even when these brands were introduced to her slowly. Things got back to normal when I reluctantly switched her back to Hill's SD.

I am aware that SD's ingredients are not as good as other better brands, but my dog likes SD food and has been on it for 7.5 years. She was a 2-year old mutt when I adopted her, and she has never had any health problems. Together with regular exercise (she walks at least 3 miles everyday) and a lot of love and attention, she is in a very good shape for a 9.5 years old. Her teeth are great and she is very perky when she walks. The only reason I tried to change her diet was because of the large amount of negative reviews about Hill's SD.

I used to have a senior toy poodle who was 11 years old and in a terrible physical shape when I adopted him. He was on SD's senior/small bites for a bit longer than 6 years; he also didn't have any health problems, but was just getting old and eventually passed away in his sleep at home peacefully. When I adopted him, I was told that he would only live for another 2 or 3 years. But he lasted longer and was healthy and perky until the last 2 days when his body started to shut down.

In addition to my own dogs, I also have friends who feed their dogs SD and are doing well. Of course, I've also known dogs that don't do well on SD. So it's kind of like people, food A is good for people A but not B.

i used to fed my dobie with this brand. Have to add meat and fish oil to make her swallow this brand. failed

My Parents and I both Have Minture Pinshers. Both feed Science diet as recommened by our vet. My dog had terrible body odor, His anal glands always seem to stink water eyes and always chewed his feet. My mother's dog did not exhibit all the same symptons but did have inconsistent bowls, body odors and water eyes. We switched to nutra ultra brand and all of these things have dissappeared. Buy your dog good dog food and do some research!

My mother's Staffordshire Terrier was being fed Science Diet by recommendation of her veterinarian. She suffered from horrible allergies. She licked and licked constantly. She also shed a lot and had a bad doggy odor. I did some researching and found out that science diet adult formulas contain corn, corn gluten meal and whole grain wheat, which studies have shown to be causes of allergies in dogs. Needless to say I informed my mother right away of this so-called "good food" and so my mom put her on Taste of the Wild grain-free Pacific Stream canine formula. She is doing much, much better! She does not lick anymore, she dosent shed like she used to, the doggy odor is gone and her coat is shinier. I wouldn't recommend Science Diet to anyone. I suppose some dogs can get along fine with it, but think of the kind of life they would have if they were fed a more nutritious food!

I wouldn't feed this crap to a person on death row and I really am not impressed with people these days. I have been a pet groomer for almost 20 years and an avid show breeder and handler long before that. You might as well feed your dog Pedigree. All those who believe exactly what your vets tell you is a fool. Educate yourself and do the research. Do you know that nutrition is not elective course in vet school. Hell I have found that most vets can't even tell what a breed is mixed with. I have heard some say a dog is mixed with some off the wall crap that the dog does not even remotely look like. But yet people believe them, because hey they are a vet. And also vets are not trained how to prevent diseases in your pet: they are only trained how to treat it. I know some people who also take everything their doctor tells them to take without any questions or research. Because they are doctors! Please! The sad thing is that your pet is only as smart as you are. Geeze, I wonder why I see so many ill manered dogs! Lori Muddy Paws Grooming

I have a 7 year old miniature pinscher. Science diet has a variety of brands specifically formulated for your dogs personal needs. For instance, light,puppy,senoir,adult, and other specality foods. I have been feeding my pet this brand all her life. She has never been sick. Her coat is beautiful and shiny and she is very active for her age. The vet has never forced the sale of food on me. I have used this product upon the reccomendation of other friends. I have never had a negative experince with this brand. I would tell anyone to use this product. Differerent dogs respond differently to different types of food. I would advise anyone to try SD and see the results for yourself.

We have a new dog that came to us in January eating Science Diet Lamb and Rice dry food, adult small bites. She does very well on it in that her coat is soft and glossy, her "ouput" in the yard is easy to pick up and not too much (we live in a condo development so that is important). She finds the food very tasty so I never have to "doctor" it up or throw out food left in the bowl. I was going to change her food to the same food her sister is eating, but have decided, based on the results to feed them both the Science Diet. The number 1 ingredient on the label is lamb meal followed by brewers rice and rice flour (the main ingredients of the kibble) and the food is preserved with Vitamin C and E. It is not a fancy food (no fruits, vegetables or spices), but is digested very well.

this is a very bad brand! it has been recalled a couple years ago and yet ppl still put it on there selfs to sell. U should stop feedig ur pet this brand one of my cats died for eating it

so swich ur food

We had our dogs on Science Diet because the Vets recommend it and that is because the Vets get kick back on it. Science Diet helps out the Vet Colleges. In reality Vets really don't know what food is the best. However, I was lucky enough to have the vet assistant tell me about Science Diet and that Canidae and Innova is much much better for the dogs. That Science Diet has too many fillers and bi-products, which is very true.
Our dogs bowel movements were way to hard, they were always constipated and went potty several times a day.
I don't recommend Science Diet what so ever

Science Diet is one of the lowest quality foods out there. It's main ingredient is corn! Dogs like people dont digest corn. Corn contains aflatoxins which is a naturally occurring fungi that grows on corn, soy, and even peanuts. These aflatoxins are deadly to your dog. This can cause things like pancreatic cancer, liver disease, UTIs, which can lead to bladder problems and kidney failure! I work at a pet supplies store and most of our foods are holistic but we carry science diet because it is a business and our owner likes the popularity of it...a science diet representative told our employees that we are NOT ALLOWED to show our customers the ingredient pannel...obviously there is something to hide. And for the person who said you need to be an expert to know this stuff...you dont...it just takes a little knowledge, research and experience and most importantly common sense to know what is good for your dog. veterinarians know nothing about nutrition...science diet funds vet schools and brainwashes them to believe science diet and corn is good for your dog. its not! if you want a good brand of dog food...try the Natura products like Innova and Healthwise or Merrick or Before Grain. Stay away from "Science" Diet...try something holistic...for the well being of your dog.

My puppy would not eat this dog food. I received a free bag from my vet. I was already feeding him Purina One Puppy Chow. I mixed the two bags together and he would only eat the Purina and leave the Science Diet in his bowl.

  I have NEVER been a Science Diet fan, in fact, have detracted as many people as possible from feeding the "overpriced, grain based junk" over the years. After all, I'd heard time and again how this food was nothing but a marketing gimmick, how the Vets were getting such a lucrative deal from selling it. Waaaay back in the day when raw diets were being shoved down everyone's throat (if you didn't feed raw in '01-'03ish you were abusing your dogs ... @@) we even used to call this brand Science Death. There has to be more misinformation, propoganda & outright lies surrounding this brand than any other, even the dreaded Purina!
     I have fed everything from raw to probably almost a dozen holistic foods over the years, including Best In Show, which has been out of business for some time, Canidae, Nutro Ultra, Back To Basics, Timberwolf, Merrick, Evolve, Natural Balance ... the list goes on. The latest in the holistic foods has been Wellness, both the CORE & the Just for Puppy. I'd been feeding Purina (GASP!!!) wasn't happy about a recent formula change, so decided to try somethign "better". HA! I have never had so many problems from a food. From compulsive stool eating and gastric problems in the puppy feed after feeding it for a few months this summer/fall to severe life threatening problems on CORE. No, absolutely not exaggerating. None of them did well - one had a seizure we have now determined to be related to hypoglycemia & dehydration. Vet believes there was great strain on his kidneys as the BUN and cholesterol were elevated - he was drinking and urinating so copiously on CORE, was just not doing well, loosing weight, and had a very mild petit mal seizure due to the havoc it was wreaking in his body.
     Anyway, I digress. On to my Science Diet review!
     I have been feeding Science Diet  Active Adult for about 3 weeks now and the changes are REMARKABLE. Just absolutely astonsihing. First, I want to say the feed has changed over the years, and is now preserved naturally, with mixed tochopherols. It is a low carb food, about 38%, which is similar to the amounts in foods like Purina ONE/Pro Plan, and Eukanuba ... and CORE. I find it's the holistic foods that are close to 50% carbs.
     I have 12 dogs, all of whom are now eating less of this product and digesting it well as evidenced by small, firm, infrequent stools. Teeth are clean, eyes are bright, very even energy level. Everyone's coat has drastically improved. Coats are soft, thick & glossy. Appetites are just ravenous! They absolutely love the taste of Science Diet :) That makes me happy because it's not possible for active working dogs (we hunt hare/squirrel) to maintain health if they pick at their food. Again, I am feeding very little to maintainweight. The largest dog, a 65lb Shepherd mix is eating 2 cups daily. He also has the best coat he's had since he was about 2 yrs old (he's 8 now) and the most unexpected, miraculous thing is that his chrinic moist, yeasty, wax encrusted ear infection is finally, after YEARS of treatment, clearing up more and more every day!!! I also had a very stiff young bitch who had a hunting injury as a pup. As of late, she's been walking aroudn hunch backed and stiff. Poor gal was very uncomfortable and lethargic. Well, not anymore. Her tail is way up, gait is normal, she is running around and is probably one of the most active dogs we own now!
     You just cannot blow off results like this. I pay about $44 for the 40lb bag, which I consider to be moderately priced. Insult the ingredients or the marketing all you want, but I have healthy Beagles (and a mutt) who are living proof that the holistic kibbles are not at all what they are cracked up to be. I hate the stupid argument that feeding SD or Purina is like feeding Mc Donalds ... while Innova or Orijen is like feeding fresh foods. WAKE UP. All kibble is processed, and feeds like Orijen are no less processed or any better because they have an entire spice rack and veggie stand in them. And for 38% carbs, you can bet that Science Diet does NOT skimp on the meat.
     So there's my review. This is one of the best foods I've ever used.

I have raised my 2 dogs on Science Diet and they are doing great! I have a 14 yr old and also a 7 mth old German Shepherd. They haven't had any health issues. My 14 yr old male hasn't had any joint or athritis problems and I don't give him any supplements. Both of their coats look great! So in my opinion I give S.D 5 stars!!! I also work at a veterinary clinic and I can tell everyone we do NOT get a kick back from selling S.D. I would also like to tell everyone the biggest things you want to watch isnt so much the ingredients its the NUTRIENTS. The most important nutrients you want to watch are the Protein-Phophorus- and calcium. (most dog foods don't list the phosphorus and calcium you need to call the company and ask). My fiance just switched his 5 Belgian Malinois from Taste of the Wild to S.D about 2 months ago and he has seen a big improvement. He switched them because when he did his older dogs Bloodwork his phosphorus levels where to high. We rechecked the bloodwork on monday and all levels are great!!! Excessive amounts of Protein and Phosphorus can increase the risk of kidney disease as your pets get older! High calcium can cause your dogs to develop stones! Hope everyone finds this helpful!

Kristy!!!
I have an Italian Greyhound who was on Iams and decided to switch
him to Nutro and the same with him, sick and threw up every day..I am
trying Science Diet today..he really ate it up,I will see how he reacts to it over this week,he is 7 years old by the way.
Nutro is CRAP and won't buy it again!

No! this dog food is garbage and is only pushed by vets bc they get a cut of the proceeds from sales.

It is plain old nasty shit.

Well... Coming from a veterinarian's perspective (who has been practicing for over 13 years, and I used to be a veterinary technician myself) my mom (the doctor) has advised me that "Science Diet is not the best, but it is not the worst." So, I will give Science Diet three stars.

What is in the dog food, nutrient-wise, does matter! It's like a baby.. dog food provides proper nutrients just like a child needs proper nutrients in order to grow.

If Science Diet works for your pet, so be it. Having a boxer that is about 16 weeks I find that he has the world's most horrible gas on Science Diet. I do realize boxers are known for their foul smell, but I will be switching. I truly think if food agrees with their stomach he won't be gagging me. :) If you have gas/loose stools, chances are something isn't working out in your intestinal track, right!? :) (So true!)

It's kind of a personal choice, I'm not going to sit here and criticize anyone for what they feed as long as it's not old Roy or Alpo.. or the cheapest crap you can find. It varies from dog to dog on how they react to each food, just make sure it is approved by your veterinarian. It might take you a while to find a dog food that seems to agree with their tummy, but it will be worth it. I will be trying Canidae or Evo as that's what my mother recommended. Good luck to all pet owners out there!

My 4 and 3 year old Pomeranian and Shih Tzu were overweight. I switched them to Science Diet Light. They are now at a healthy weight with a healthy coat and seem to like the food. Diarrhea is a rare event now. Additionally, I have an 11 year old Yorkie. Her coat was dull and it looked as though she was balding on her back. I switched to Science Diet for Mature Adult and she looks great. My vet recommended it and even said that it was a really good diet and he doesn't even sell Science Diet in his office - he sells some other prescription brand I can't remember the name of.

I noticed in all three dogs that when they did go use the restroom, their feces is a lot more solid, and there is more - I don't know if this is good or bad, but they seem to be less bloated and constipated and do not have trouble going now.

The vet had informed me that Science Diet has less fatty ingredients and more nutrients. Therefore the dog is absorbing more of the nutrients than the fat and feel fuller than when they eat low-grade dog foods.

I am surprised to see the many bad reviews and noticed that some of them say that the product was purchased in the Phillipines. I am in the United States - Texas and have not had a problem.

I guess different foods work for different dogs.

This is a helpful site to help those who are interested in learning how to read a dog food label based on the AAFCO regulations. Just remember that a lot of these dog foods are formulated to cut costs. 

The primary ingredient in the food is a low quality grain. Corn is a problmeatic grain that is difficult for dogs to digest and thought to be the cause of a great many allergy and yeast infection problems. We prefer not to see this used in dog food, yet it is the primary grain in this food.

When I bought this dog food a few months ago, all 3 of my dogs turned up their noses to this food. When they realized that's all they were getting that night, they ate some of it. Then the next day, 2 of my dogs had horrible diarrhea. Won't ever buy this food again. My dogs are not picky and will eat just about anything. They now eat Taste of the Wild and have lustrous coats and look forward to eating their supper!

My Great Pyr. surgeon recommended science diet j/d. I can see a change in my big boy already. I have to mix the dry with canned to get him to eat it, but other than that this food is working for him.
He was diagnosed with Arthritis and Osteochondritis Dissecans at the very young age of 2 1/2. I wish I had always fed my baby this food.
Thanks,
Mary of Alabama

I wonder why the Science Diet is rated so low by so many people, then I came to read the reviews and found that most of the people gave it a bad reviews based on the ingradients on the bags. Well, here is what I think. I've been feeding my dog many different brands but he's always been weak on the stomach. I even tried what the pet store recommanded, and he never had good reaction to it either. He was "fine" with the cheap supermarket Pedigree, so that's what I've been given him for years. Until he was diagnosed with Addison's disease. After surviving it, although needing to be on medication for the rest of his life, he lost so much weight, and lost a lot of hair. He was extremely boney, and going bald! Finally, out of curiousity, I picked up a bag of Science Diet for Senior dog, supposedly a newly developed formula. It was the biggest miracle ever to see him becoming his normal self again, now with full hair and gaining his healthy weight back, but not over-weight. Ever since that, I know I'm sticking with this one, and sticking to this particular formula.

Edit: I would first trust what the "real" experts have to say. "Real" experts do not include those who have done researches on internet, nor do they include those who try to impose their own liking or disliking of dog food ingredient on their dogs. Second, I trust my own experience. My experience does not include what I have read on the internet, especially not what I have read from the people who think they are experts on RIA. Now, for those who disagree with SD and want to feed their dogs with what they call the more superior brands, feel free to do so and stop harrassing others who do like SD and will continue to feed their dogs such food. It's an opinion network, not a brain washing network. Read all posts at your own discretion.

This food is low quality.  The people who are arguing just seem to want to be argumentative about the product.  They're hurting their dog so they can be "right".  Please don't listen to them.  If you have any common sense in your body, take a look at how many negative reviews there are.  Go to the first page of reviews and pick a brand from there.  You won't find pages and pages of negatives there, what does that tell you?

read the ingredients than you will see all by-products, yellow corn, soybeans and sorghum all great cattle food and chicken waste. Its crap and some low end vets who are only after profit suggest it and why? They get great kickbacks from so called "science diet" for medical equipment etc and their profit margin is to die for, I know, i worked for vets for years. Buy something better and love your animal, PLEASE.

Kristy, a veterinarian with a Ph.D. in veterinary NUTRITION told me that Science Diet has the very bests NUTRIENT PROFILE of any pet food today.  I would believe him before I would believe self-appointed internet know-it-alls who have no technical background in nutrition.  Don't change foods!

It's hard to read these reviews with an open mind...the negative criticism does seem a tad misinformed. Take the debate about corn in the food, for instance. Something tells me that the reviewers refusing to provide this brand of food to their dogs haven't eliminated corn out of their own diets. If they had, that would mean they weren't eating food starches, corn meal, sucrose, vanilla, corn-anything...this means no soda pop, no fruit juice, most breakfast cereals (containing malt), anything preceded with the word "vegetable," toothpaste and mouthwash (containing sorbitol), the list goes on...

I think a good way to evaluate the integrity of your dog's food brand is to first determine whether you believe in the brand's values (does it care about a holistic approach, for instance), then look at how the company is supporting those values (through research? philanthropy?)? You could honestly go nutty if you attempted to make an informed decision just based on reviews...how does one determine what's real and not, what's truthful and not?

Happy food hunting.

I have been feeding my dog (Boston Terrier) Science Diet for 10 months. We started off on the Science Diet small bites puppy dry food. I got nervous after researching the internet and finding so many negative reviews that I tried to switch our dog to Nutro around Christmas. She got very sick off of Nutro and threw up every day she was on it. I introduced it to her over a week period and she still got sick. I switched her back to SD 2 weeks later and she has been fine ever since. We now have her on Adult SD small bites and she loves it. Gobbles it right up. I did check the ingredients on the adult food and the first one is chicken followed by ground whole grain corn. I do know that with the SD puppy food, chicken is not the first ingredient. In fact, I do believe it is grain but I really don't remember. Her black coat is nice and shiny and we have had several compliments on it. However, due to all of the negative reviews I have been thinking about switching. The reason why I haven't is because she loves SD. As of now, we have had no problems with it.

my pups don't like the taste, and refuse to eat it

My dog had been eatting SD all her life. She never gets into the trash and I make sure she takes all her supplements. Well, I was very surprised to hear from my vet that she had developed pancreas disease. I sometimes wonder if her dog food is at falt. I did notice a bit of a spoiled smell when I openend a can of W/D one time. I have since stop giving her Science Diet but I feel the damage is done.

Crap ingredients.  Read the label.  Even worse than some grocery brands.

Science diet makes me laugh. They really rely on using science as part of the name to make it sound advanced or something lol wow. Anything can be made 'scientifically' but that doesnt make it good. I can scientifically make a dog food out of rat poison if you like. SOme of the older generation people are easily fooled by imagery and advertisements like this. I think as time goes on people are going to catch on a little bit more and realise what's behind all the false imagery. ANd for the record so many vets recomend this food because they make profits for selling it and in vet school science diet sponsors alot of money to the schools and try to get their money hungry hands in there to get to the vets and make them think its the best food out there. The truth is almost vets don't learn about animal nutrition in vet school and may know just about as much about dog food as you. IF the vets do learn anything about nutrition it's usually a program made by science diet and sponsored by them, very very good for their buisiness you see.

science diet was prescribed by my vet for intestinal disorder he is a 10 year old chihuahua mix he hates it so much he would rather starve he got diarea and vomited and had abdominal pain , cook your dog a good home cooked meal, hills is crap, my cat would not eat it either he starved for a week and we gave up and gave him his old food

The ingredient has always been bad, after I look at the "Nature's Best" ingredient list, I think this food is absolutly garbage, a waste of money.... pork fat....this is not recommanded for human, and they put it in the dog food... terrible.

Worst value in dog food not only is it bad for your dog its costly. People who buy at Supermarkets and Farm Supply stores probably actually think they are getting some decent food by paying extra. Some have corn meal as the #1 ingredient. Bad choice ZERO stars

My vet really pushed this food on me, so I switched. My dogs were on it about 5 months and it made their fecies yellow and runny and they just didn't seem as healthy and energetic as they were. After taking a look at the ingredients I am very disappointed in this food, especially for as much as it costs.

Don't feed this to your pet. Their quality control is terrible. They formulated a prescription product with poisinous wheat gluten that was recalled (hills m/d dry feline). It killed one of my cats and caused permanent kidney damage to the other. The melamine and cyanuric acid were visible per the FDA and their quality control missed it. I'm an analytical chemist that has material quality experience and they obviously didn't do their job, not to mention that this product was recalled a full 2 weeks after everything else. For as high a pedestal as they put themselves on, they shouldn't have missed it. My cats are now on Orijen by Champion foods and are doing so much better. If I could give this brand zero stars I would.

I was a skeptic from the beginning and recently moved into the states from Toronto Canada. Our vet in Toronto never mentioned the food and never pushed it on us, but would always have a few products in the office that she supported, not one was science diet. Also the local pet food supplier never carried any of hills products. Now the local pet food supplier here in South Carolina says not to feed my dog SD, but the new vet does and the office is filled with SD and Hills products. We were unable to get the same dog food we used in Canada so we Tried SD (Im embarrassed to say) my dogs coat changed, gained wait, lost energy and would not eat until late evening till the poor guy realized that was it. That was for 6 months.6 months to dam long..Try looking @ Wellness, they are an old mother hubbard company wich makes all natural treats and food. They have a new line wich is called Core its Protein focused and grain free. Its based on the raw food philosophy providing nutrient-rich, high quality meat to a dogs diet. Now you would have to see it to believe it, but he will eat his food before touching a bone that is filled with a little peanut butter. It's nice to see him enjoying eating and become that little puppy all over again.

If you bought it in the Philippines, it s crap anyways. In the US this is the best dog food. My dog got sick eating Nutro and Purina. Science Diet has never given me any problems and my dog is healthy and has a beautiful coat. Every dog owner I know uses Science Diet.

I used this for about a month as my vet had told me it was a good food, then the puppy started to throw up. So I looked up every ingredient and was shocked by corn being the first ingredient in the food. So I swiched foods and he is doing great now on a much better food.

I have been buying the Hills Science Diet Puppy Small Bites for my chihuahua since I've had him. I got him when he was 6 months old; he is now 9 months old. He has been normal as can be, and I feed him Hills Science Diet every day. I love him so much and try my very best to take very good care of him. I would never buy a dog food, or anything for him, for that matter, that would harm him. My vet did not recommend this food to me. I looked up dog foods online myself and decided to get Hills Science Diet. I believed what I read on the Hills Science Diet official website, as follows:

...It seemed like a good food for my puppy. I don't know anything about dog nutrition so it's obviously possible I made a misinformed decision. But how am I supposed to know which ingredients are good and which ones are bad? When I took my puppy in for his shot appointments, the nurse asked what food he was on. When I told him Hills Science Diet, he didn't say anything negative about it. In fact, he didn't say anything at all about it except for 'ok.' If I can't trust what Hills Science Diet says, and I can't trust my vet, then who should I trust? A bunch of people that I don't know? Do any of you have any actual proof that this food is bad for dogs? Just why would anyone make a dog food that would harm a dog? I want to give my puppy the best nutrition possible and now after reading all these reviews I am so very lost. I don't know what food I should give my dog now. I don't know if I should call my vet and ask about it, or if I should call Hills Science Diet.

I just did some research online and found that BHA, BHT, and Ethoxyquin are not in the Hills Science Diet Puppy Small Bites that I feed my puppy. I read through all the ingredients on the bag. I also found that corn/grains do not harm dogs; they are just a little harder for a dog to digest. My puppy seems perfectly fine and healthy; he just got neutered last Friday and has already fully recovered. There have been no signs of his food harming him in any way. I guess I'll keep feeding him the Hills Science Diet food and at my other dog's shot appointment I will talk to our vet about different types of dog foods and what is best to feed my dogs. Again, if this brand really was harmful and killing dogs, I don't believe it would be on the shelf.

Please, please people understand ~ just because your vet tells you to use it, research!  Bottom line ~ doesn't your pharmacist know more about your pills than your doctor?  Vets are given VERY LITTLE education on nutrition.  They also get paid to push the product!  If you listen to Science Diet spokespeople, they first will tell you that corn is GOOD for your dog.  If it is soooo good, why are they now taking it OUT of their new products.  Common sense!  The food is once of the WORST foods out there ~ especially for the price.  Ground corn is their #1 ingredient ~ what does corn do to a dog?  Well, what does it do to you???  LOTS of stool with this product, too many fillers which, in turn, for the company, means you will buy more.  YUCK!!!!!!!!!!!

This brand is a piece of crap! My 4 year old American Eskimo used to have perfect healthy skin coat until I started to feed him science diet.

My dog hates this food.  Hates it.  I was always under the asumption that SD was the best you could buy.  After reading the ingredient list it's rather crappy for all the hype it gets.  It's not a terrible food but there are others out there that would probably do your dog better.

ok so heres the reason most of you probably feed your dog or cat science diet, because your vet recommends it right, well just because your vet recommends it doesnt mean its good, i used to work in a veterinary hospital and the truth is the reason that vets recomend it is because they gain commision off of it, truth be told this is actually a horrible food, if you want to feed your dog or cat a good healthy food i would try canidae or if your dog has a strong stomach wellness only because it is a very rich food

All I can say is..... I have tried EVERY dog/puppy food out on the market from Nutro to the organics to Blue.... I stayed away from Hills/perscriptive science diet because of all the negative press and sites regarding the supposed "crap" that is in the food. Unfortunately, after numerous $$$$ spent trying to figure out why my 14 week old doberman puppy had major diarrhea every day 4-5x a day (kept us up every 1.5 hours needing to go outside to have the runs) all tests came back negative. The ONLY food that does not give her ANY diarrhea is Hills. If anyone out there can recommend another "easily digestible" food that is less than Hills.... I would be more than happy to give it a try. For now..... Hills it is because it is keeping her happy and letting me have a decent nights sleep.

I've been feeding this crap to my dog since we first got him. and because I heard from my puppy class that the fillers in science diet are wood shavings and so on. so then I did some research and it told me even more fillers that can give your pet antigestion problems. and I had noticed that my dog kept throwing up and wasn't as I hiper. then I started to notice that he wouldn't eat his food and then I noticed that he preferred to eat the grass and twigs in the back yard. I finally gathered enough information to decide to not buy it any more
