  • Great for both our senior mini dog and our bigger hound.

    By on

    The pieces are small for my smallest dog to eat. They're not so tiny for my 60+ hound, to inhale. It smells fresh to us, and not like some of the other greasy 'dry food'. It's expensive, to purchase but the discounts for monthly auto reordering, and fast auto delivery make it easier and more affordable for our family. Glad we found Chewy.com. Hopefully we will be lifelong friends.

  • Loves this stuff!

    By on

    My dog, Buddy, half mutt and almost all big beagle, loves this food. I get the small bites for him, though, because he's 12 years old, and the smaller bites are easier for him to chew. He's never had any issues with Science Diet, and he's been on it for almost 2 years now. I will continue to use this dog food unless my vet tells me otherwise.

  • Highly recommend this food!

    By on

    Our dog has eaten Science Diet since we was a puppy and at this stage in her life, this food is perfect for per progression as she gets older. She is still very active and this food helps keep her that way. I highly recommend this food as dogs turn 7 years old.

    We have 2 West Highland Terriers and they will be 14 years old this year. When they had their first puppy wellness visit our veteranian told us to always feed them Science Diet dog food due to the fact the formula from puppies to adult dogs is always accurate and very healthful. Our dogs are beautiful and very healthy. Thank you Science Diet!!

  • Dry dog food

    By on

    The size of that food was very small. I have a 7 pound silky terrier. I've been buying small pieces ofother brands of dog food but the pieces were too big. You are perfect size for a small dog. The other one she swallows whole this one she actually chews.

  • Love it!!

    By on

    My Maltee-Poo absolutely loves this food. I have seen a complete change in her energy level and temperament. Make no mistake, she has always been a decent eater, but now she can barely contain herself at meal times. I also incorporate the canned food with the dry, and it makes her very happy. Chewy has made it affordable and convenient with autoship.

  • It's the one dog food my rescue poodle will eat.

    By on

    I tried a lot of foods and Hills Longevity Small Bites is the one my rescue dog chose. Her choice is the one that counts so we're sticking with it. She was so thin when I picked her up from the shelter and her coat was poor but now, due to good eating habits and lots of love, she's filled out and I can scarcely tell her apart from my other little poodle which we've had for ten years. My second item ordered from Chewy was a prescription dog food for my older poodle and Chewy obtained the prescription from my vet and the delivery was very prompt.
