Science Diet Dog Food is one of the more expensive brands available at “big box” stores, though it is highly recommended by veterinarians. Oddly enough, though, it is generally considered to be a strictly “middle of the road” brand by most dog owners. Both the dry and canned foods only contain a rather moderate portion of meat, and the food itself generally seems to be filler. Dogs in general may or may not like the product, though it seems that most animals tolerate Science Diet about as well as any other form of kibble.
In general, it seems that consumers would be happier with the product if the price was a bit lower. It has similar ingredients to most major dog foods, but costs over twice as much as some of the more popular brands. Science Diet is definitely not a bad choice for dogs, but it might be a bad choice for your wallet.

The company who makes Science Diet dog food is called Hill’s Pet Nutrition. Aside from Hills Science Diet, Hills Pet Nutrition also makes Hills Prescription Diet formulas, which can only be purchased after obtaining a prescription from a veterinarian.
Though none of the Science Diet dog food formulas were involved in any recalls, several of the Feline formulas were recalled in 2007. The affected brands were several of the Hills Science Diet Feline Savory Cuts.
Dogs with food allergies may experience symptoms from some of the ingredients contained in Science Diet dog food. Common allergens include corn-derived ingredients, chicken (or other protein-specific allergens) and soy ingredients.

After dental surgery I was advised by my Vet to feed my dog Hillis Prescription Diet. Even though she had done very well on Wysong Nurture I decided to follow my Vets suggestion. One week later she developed hot spots – and after three weeks on meds. (diagnosis – perhaps medication from her surgery) I finally suspected the dog food. She has been off it for 1 week now and cannot come to a definite conclusion but signs indicate the dog food is the culprit here. I am not comfortable with the ingredient list of the Hillis food so I am going back to Wysong. I will discuss this with my Vet but I do not have any intention of returning to Hillis.
Moral – if she is doing very well why change? My bad decision her suffering.

We were recommmended by our pets Foster Parent to get Science Diet for our 2 yr old Shar-Pei Pointer Mix Shadow that we had just adopted. Per her advise we did so. With-in 3-4 days Shadow woke up one morning not his usual happy jumpy kissie self. Then we noticed that he was not wanting to eat any of is food and had no interest in treats. Let me tell you that boy loves his treats!! So we took him to the vet and he had a fever and a urinary tract infection. We were given antibiotics and some special food. Once we ran out of the special medicated food we once again gave him the Science Diet, just to see how it went, because we just werent sure if that was the cause of everything. Well this time it only took 2 days and he was already showing signs of larghy and lack of intersest in food and treats. We have decided to taked Science Diet Back and have exchanged it for a more natural food. While we were at the store we had a lady come up to us and say “Never buy Science Diet it killed two of my dogs!” and a manager of the store came over and said that she wld not recommend Science Diet to anyone. That all it is is OLE ROY repackaged with a giant price hike. There have been lots of complaints of allergy type complaints that we have read on line. I wld not recommend this food to anyone and it really disguste me that the vets get paid really good money to endorse this product that is out there making our dogs very ill and in some cases even killing them. BEWARE!!!!

We’ve been feeding our pug dog Science Diet Lite small bites for a long time. It seems to agree with him except he has skin allergies and I think the corn in the food may aggravate his condition.
Also the last bag of food we bought had a very strong odor that none of the bag of food had before. The smell was not like kerosene but strong and similar. Could you comment on my concerns.

My pups, Casey & Toby, love Science Diet Healthy Developement Original Puppy Food.. They chose it over all the rest, from cheapest to most expensive.. Because they are so picky, I had to try them all.. I am very pleased with the results.. It has improved their coats to a gorgeous shine, and smooth skin with no dander.. A big improvement over their previous puppy food, with results within days.. They are perky, happy- go-lucky, the softest & shiniest ever, and just all around healthier.. Casey, Toby, & I highly recommend Science Diet to all puppy owners.. I believe u won’t be disappointed.. It is a brand I truly trust..

I rescued a German Shepherd who had epilepsy, constant intestinal issues, bad gas, skin infections. He had been raised on Science Diet.
My vet recommended keeping him on science diet – in fact – that’s what they sold.
I kept asking my vet – is engineered corn really what my dog is supposed to be eating? They said it’s been scientifically proven. After 6 months of dealing with repeated antibiotics for diarrhea and horrible gas, I ignored my vet and slowly switched to Taste of the Wild. Every dog is different – I think mine had corn allergies. He became more alert, no more diarrhea, less seizures, less skin infections.
I also switched vets.

Regardless of whether your dog does well on the food or not, it doesn’t erase the fact that you pay for a brand name and a whole lot of corn. Corn is often the first ingredient of many formulas and if it isn’t, you are paying more (such as the lamb formula). Vets recommend this food because Science Diet sponsors these vets and pays for their schooling. I’d stay away from a company swayed.

How do you know vets are paid to endorse this product? Or are you just speculating and perpetuating rumors?

Its no different then your family doctor getting free samples from drug companies. Your doctor gives those out for patients to try. Doesn’t mean they are being bought off by the drug rep. Sure the vet may get SD product at a reduced price to sell but that is in every business. They do not pay for any vets schooling. They may have Vet school scholarships available, but that is a far cry from buying them off.

Hills may not pay for individuals schooling but they sponsor and pay for tons of veterinary programs and do give vets incentives for pushing their products in their practices. Its not a speculation, look it up. Plus, having a vet tell you that fact to your face makes you believe it as well.
