Rated 4 out of 5 by from A dependable brand! My dog has a very sensitive stomach, and any changes to his menu can cause extra gas and loose stool. I have to say the first day I added this to his dish, yes, it upset his stomach for just that day but just the following morning he was fine, his stool was solid and his gas went away. Typically it takes my dog 3 days for his bowel movements to get back on track, so this proves to me that Science Diet is easily digestible for even the most sensitive of pets. I have a Papillion mix and one of the main reasons why I love this food aside from the ingredients is the size of the kibble! It's hard for me to find dog food that caters to smaller dogs.

Rated 5 out of 5 by from Wouldn't change my dogs' food if I could This has been the best food I could give my dogs. Their coats are soft and glossy, eyes are bright, they're in perfect shape, and they seem to love the taste. We also use the wet food for their morning feeding and it has never upset their stomach. I also appreciate the small bites version of all of the foods you offer! A dog I had prior to the ones I have now had horrible allergies that would result in very itchy skin. I regret not feeding him Hill's. I did feed him the Prescription Diet and it helped so much but after the vet took him off of it, I never fed him another version of Hill's and I'm sure if I did, he would've felt better. I'm so happy and pleased with the results of this food with my current dogs! These dogs are family to us and I don't want to feed them "just anything". They deserve the best so that they can live a long and healthy life! With this food, I believe we'll achieve that. Two paws up!!!

Rated 4 out of 5 by from My Yorkie likes Science Diet When I adopted my Yorkie his foster mom had just started him on Science Diet and he has been eating it for 2 1/2 years now. Tried changing to a different brand that advertises its got better ingredients but he didn't like it and started having difficulty "doing his business". Switched back to Science Diet Toy & Small dog dry plus Science Diet wet and he hasn't had "business" issues and he likes it. Science Diet seems to making ingredient changes which makes me feel better about feeding him their product. Plus they just made the kibble smaller which is easier for him to chew. There aren't a lot of products out their for toy breeds, and the ones I've seen are extremely expensive. My Yorkie does well on Science Diet, he's got lots of energy, maintains his correct weight and most importantly, he eats it.

Rated 5 out of 5 by from Promotes Healthy Skin and Coat, and Maintains Ideal Weight I have an 18 month old Chihuahua named Lulu Belle, and I have fed her Hills Science Diet foods since the day she came home to live with me. She was the runt of her litter, and I was afraid she would stay tiny forever, but with the help of Hills Science Diet foods she has reached her full adult weight of 5 pounds! The vet always comments on how healthy her skin and coat look, and praises her weight as being "just right". I really like the fact that Hills Science Diet foods and treats come in a variety of age and weight varieties, making it ideal to continue feeding it at any stage of life.

Rated 5 out of 5 by from Love this Food! I have trusted this brand for my dog since the day I picked him up. The pet store highly recommended this dog food and explained's real, natural food my dog would eat. If you look at it as this dog food is like cooking a nice home cooked, healthy meal for your dog everyday compared to other name brand dog food that you buy in supermarkets that are like bringing your dog to McDonald's everyday. And it's true! Have you ever read what is in your dog food?!?! I trust this brand and my dog loves it! Every now and then I add warm chicken broth to it as a treat for my dog. I would not change brands, ever!

Rated 5 out of 5 by from Excellent taste for small teacup dogs. My teacup poodle, Bonnie, loves the Small Bites. I recently changed to the Advanced Formula for Small Dogs. She likes it even better. She has done really great on this food. She was rescued from a puppy mill in Tennessee and we have never fed her anything buy Science Diet Small Bites. I am considering changing to Oral Care because her teeth are bad, She developed 2 sets of teeth before we got her, due to the poor diet she was fed. We had one set pulled, but now she has poor teeth. She only weighs 3 lbs and is the light of our life. Science Diet made her healthy.

Rated 5 out of 5 by from Simply the BEST!! I have a 4 year old toy poodle, I have been feeding him Hills Science Diet since he was 5 months old. I obtained a sample pouch from my Vet, and have used the small and toy breed formula, first for puppies, then adult after he had his 1st birthday. I would not use or trust any other brand for my dog. He is healthy, maintains a healthy weight, and has shiny, soft hair and eyes!!! With all of the recent scares in dog food, I KNOW my pet is safe!!! Hills is made in the USA, and he LOVES the bite sized flavor kibble!!! THANK YOU Hills for making a superior product that we can rely on for the happy healthy life of my toy poodle!!!!

Rated 5 out of 5 by from This food makes my dogs' coats shine. My two smooth mini dachshunds love this food. One of them is a picky eater and I had a hard time finding a food that she would eat eagerly. Their coats are soft and so shiny that our vet even commented on it. The higher fiber level in it seems to agree with their digestion better than a lower fiber food did. They have great energy and love to play.The small kibble size is just right for them. I like that the ingredients are named ingredients and not just generic types of ingredients. I also like that the dog food's AAFCO statement is the feediing trial statement and not just the formulated statement. I think you can make any food look good on paper but the proof is in the feeding. I would like to see this product in a larger than 15.5 pound bag.
