  • My pup finally eats

    By on

    So my pitbull hasn’t lost all her baby teeth and we’ve noticed she can’t eat regular large breed foods. So finding the tiny bites helps for her age. She has had many challenges in her life and slowly getting past them but eating should never be one of them.

  • Great Deal

    By on

    My dog Koda was prescribed by our vet to start eating this food as she was overweight and needed to lose some weight. we were buying this same dog food from the vet and it was twice the price at the vet than what we could get from chewy. My dog loves the new food and we can buy larger amounts than what was offered at the vet. Koda has lost some weight and is much more playful than she has been. Finding Hill's Science Diet Light Small Bites at Chewy is a win for us and Koda. My dog is a cross between a chiwawa and dachshund is a little over ten pounds and is very happy with the new diet.

  • Important...

    By on

    It's important to me that Mikey gets a food that doesn't have a lot of "junk" fillers. He's a little old man & I want to keep the little old man around as long as possible. It's also important that he likes it. If he doesn't eat it? Well then, I've wasted my money. Fear not. Mikey loves it.

  • Really Small...

    By on

    I actually should pay more attention to what I purchase, our dog is large and this kibble is really, really small. I'm not sure, but I think Milo swallows it whole. It is the same recipe as the other size, but it is for a much smaller dog. Milo doesn't complain and I'm not either, just be sure which bag you buy. Chewy.com has such a huge selection, sometimes it can be tricky if you're not on top of things. Thanks Chewy, you guys are awesome!!

  • Great for my tender tummy boy!

    By on

    We settled on the Hills when we adopted this boy and it was the only thing that didn't upset his tummy. We've stayed with it as he ages, migrating to the light.

  • New diet meal

    Changed brands because I wanted a well known brand to feed my Chihuahua mix and control her weight. Change did not irritate tummy.

  • Lite food for older dogs

    By on

    We have been using lite small bites for our 9 year old toy fox terrier, it seems to have helped to keep her weight under control and she likes the taste of the product.I would recommend this family of products (hills science lite little bites ). We also impressed by Chewy's ease of purchasing & fast shipment & cost savings over cost for food from vet's office & feed store is a nice bonus these day's of fixed incomes.

  • Recommended by breeder

    By on

    The breeder we got our dog from used and recommended Science Diet so we got the light version since our dog isn't very active most of the time! She likes it fine although she occasionally chokes a bit having the small bites definitely makes it better! We also spray a bit of water on top just to make it a bit softer and easier to eat! Overall, very satisfied!
