Rated 5 out of 5 by great results.. in short , Science Diet is the only selection I will give my pack of 7,, they range from 2 to 9 and while they are not hard to please,,,because of the range of food from Hill's, our dogs are healthy and have no problems,,,they do know the difference if for a min I try to change their food,,because they won't touch any other,,,did I say they are too smart for their own good;) ps below a couple of my older boys...

Rated 5 out of 5 by Good for my dog I have two pit bulls and one of them has a very sensitive stomach and science diet is the only dog food he can eat. I tried to switch him to a different food (the proper way of mixing the two types together for a week) and my dog started getting very gassy and having diarrhea. He stopped eating and drinking and was very sick. Once I nursed him back to health with chicken/rice and chicken broth, I started introducing the science diet back to him and he has been good ever since. It's the only food that I will keep my dogs on. I just wish it didn't cost so much because with two pit bulls, I go through quite a bit of dog food. :) December 3, 2014
Rated 5 out of 5 by jonesy loves this brand when we got our lab, the brand breeder had him on gave him diarreha. after a trip to the vets (not parvo) they suggested changing brands immediately. as my brussel griffons and rescued dog love your brand, we changed the labs. he is now 1yr old, 110lbs and very healthy. i had a coupon for mobility food, tried it since he's in the pool daily, he's become quite the swimmer. in fact the lab on the bag looks just like him, my husband cut the picture off bag and kept it!

Rated 5 out of 5 by Best Food yet for big dogs I have 2 large dogs--one is a German Shepherd and St. Bernard mix, and the other is a Bernese Mountiain Dog. Both of them do really well on the large breed lamb and rice. The Bernese probably could eat any kind of food, but the Shepherd mix can only eat lamb and rice because he has a sensitive stomache. I can't stop them from eating each other's food, so I figured just feed them both the same. The cheaper foods simply do not compare. Both dogs will gain weight and their coats do not seem as shiney. I would rather pay more and have them healthy and happy! May 28, 2012
Rated 5 out of 5 by My dog thinks it is Tasty! I have a picky Australian Shepherd, who I have tried out multiple types of SD food with. I just bought him this food yesterday after seeing another friend use it. He got very excited after he tasted it, and he seems to love it! Science diet has always helped my dogs be at their optimum health, and their coat is always shiny when they eat it. The kibbles also smell good (to me)! When I open the bag I can smell them! I think he really enjoys this food so far. I would recommend it to any other picky pups. July 17, 2013
Rated 5 out of 5 by Great Product My dog and cat both really enjoy this pet food a lot. September 7, 2014
Rated 5 out of 5 by Diarrhea Solved When we got our lab 7 years ago we had an awful time with his bowls. He had regular diarrhea. We were told to not let him swimm, not let him eat the grass, that he had an infection, but nothing seemed to work. I spoke to another vet about it and she recommended Science Diet's Lam Meal & Rice because she thought my dog might have a beef allergey and she was right. Just days after starting him on this he was normal and has stayed that way ever since. May 16, 2012
Rated 5 out of 5 by Great for Large Dogs! I adopted my Great Dane/Lab with Rescue & my Veterinarian. He was very ill with ear & skin infection. We could count his ribs. He was very close to having a heat stroke. The rescue and veterinarian gave him medicine and your Hills Science dog food. And so have I he is so happy and healthy. When we take our walks I am asked what dog food do u give him. His coat is so beautiful! I tell everyone Hills Science Diet !!! August 29, 2013
