Rated 5 out of 5 by from Adult-Small Bites I adopted a 5 lb. Miniature Pinscher . He was rescued from a horrible situation. 5 lbs. of skin and bones. Coat was dull, skin was dry. Eyes had no sparkle. Bought "Red" the Adult Small Bites. Well/...he sat there at first, smelling and looking as if to say..."I don't know what this is, but I'm gonna eat it up"! and boy...did he!!! He little teeth chewed each small kibble with precision. And dainty too. Ok, I thought. He's just hungry. NOPE. Twice a day I fed him and twice a day he ate the Adult Small Bites as if it were steak!!! Today, Red has gained 2 lbs. and with the vet's approval,I might add. His coat is shiny, his skin gleems and so do his eyes. See what a good food will do. And Red is now an OFFICIAL member of our family!!!

Rated 5 out of 5 by from Overall good quality, vet recommended. We've fed this food to Bailey, our female Yellow Lab for a good part of her life. 3 cups/day, and she stayed at a pretty constant 68-69 lbs. When she turned 7, I switched her on and off to the mature senior 7+ food and she seemed to put some pounds on. Then we switched back to the adult light. Now she's almost 9 and the extra weight seems to be more stubborn (kinda like people as they grow older). Our first vet recommended the Science diet brand and we have not had any complaints. We'll see what our next checkup brings. The food is a bit pricey so you have to always look for the sales and buy the bigger bag. But if you love your dog - she's worth it.

Rated 5 out of 5 by from Long Time User for multiple pets I have been using science diet for over 15 years - have used other brands just to see if pets would like better, but only for a while - so have stayed with Science Diet for constancy and the pets ALWAYS like it. Shiny coat, strong teeth and muscles, keeps them regular (if you know what I mean) and Vet Recommended, too! The value is in that your pets will keep getting clean bills of health at the vet, less dietary complications, and reaping the beneficial amenities put into Science Diet products specific to your pets age and needs. Note, that they do have a line of products should you pet need dietary special needs due to illness or weight issues, too!

Rated 5 out of 5 by from My 5 Dogs Eat Science Diet I have 5 dogs... all are rescues. My first was a White Shepherd mix. Then we adopted a Boston Terrier. We fostered for Florida Boston Rescue and ended up adopting 3 more Bostons. They are all fed with Science diet... most of them get the adult advanced fitness. Every dog we own or fostered has done extremely well on Science Diet... even though they had various problems. It is easy to find the right food for each one on your website. I will continue to use Science Diet for all my dogs and will recommend it to everyone.

Rated 5 out of 5 by from This product is wonderful Our lab is high energy, loves to run, play and eat. He's not just our pet, he's family. We want what's best for him, and Hill's Science Diet Advanced Fitness gives him everything he needs when it comes to nutrition. It's the only food that seems to keep up with his appetite & energy level. And, he loves it! If you try to offer him anything else, he just won't eat. We have tried other products, but they don't provide the right amount of nutrition, or satisfy him. Other products do not agree with his digestive system either. Science diet is the only brand that does. It's been a totally wonderful experience for all of us! A happy, healthy friend is a great thing!

Rated 5 out of 5 by from great food, great value, great benefits. My dog Amber loves Oral care. During a time of financial difficulty I switched to something cheaper for a few months and what a mistake. She gained weight, she started having health problems, and she lacked energy. Any other food that I have tried her on she never got full. She would eat as much as I could give her and then be begging for more. On oral care she has great teeth (at over 7 years old) she has lost the extra padding without starving, and her health problems have cleared up. She has a gorgeous coat and her breath is that of a 1 or 2 year old dog. She has energy and can out run all the guys on my husbands softball team. Thank you hills for providing a food that we can count on year after year.

Rated 4 out of 5 by from I've used it for 20 years I've used Science diet for 20 years back when I had schnauzers, The oldest one lived to be 17 years old before we put her down. I have black labs now, I've always had labs, I just love them so much!! My 3 year old lab started having loose stools, So like an idiot I let the lady at the store we buy our dog food from talk me into a grain free dog food, OMGosh was that ever a HUGE mistake!!! Anyway, the grain free dog food caused both labs to have horrible diarrhea and horrible gas as well, it was a miserable 2 months!!! I finally got tired of my dogs being so miserable I loaded up the 2-1/2 bags I had left, took it back to the store we buy our dog food from and told them I needed to return it. I grabbed a cart and loaded up 4 bags of Science Diet and 2 cases of the canned (packed) dog food, checked out, went home, I didn't even do the slow transition, I just opened the bag, filled up their bowl and then grabbed 2 smaller bowls and opened 2 cans of the canned dog food and they were in heaven and after about 3 days their stools were back to normal, never again will I switch!!!

Rated 5 out of 5 by from Most trustworthy dog food brand I only buy hills products for my dogs, because I believe it is superior to other brands. I have done research on different types of dry dog foods, and Science diet foods have never had a recall in their history in which any animal was harmed. They have only had one recall issued by Hills, because they didn't like the quality of a certain ingredient. Which I find this to be a very trustworthy company, If their ingredients are not up to their standards they will not put the product out. Where as there are many dry dog food brands that regularly have recalls due to animal deaths, and the companies do not really even care. I love my animals, and want to give them the best lives that I can.
