    I was really skeptical about ordering the Hill's Science Diet because I have tried so many different kinds trying to get my picky Lhasa to eat something good for her. I must say she really took to this dog food right away and normally it takes her days to even consider trying new. I am well pleased with my purchase and the price was once again unbeatable! I LOVE Chewy.Com!!

  • Our Chihuahua puppies just can't get enough!!!

    By on

    Was looking for a dry dog food with the "right stuff" to help our puppies mature. Decided to try this one and they loved it!! They are both growing to beat the band ( one gained 2.2 lbs in the three week interval between vet visits). The vet couldn't believe it was the same dog she saw three weeks earlier!!

  • Happy puppy

    By on

    My 8 month old Chihuahua/Pomeranian puppy has been eating Science Diet small & toy breed puppy chow since I brought her home. She is happy, healthy, and frisky. I will keep feeding Science Diet as she grows up. I'm a senior citizen and it's hard for me to carry home bags of dog food, so I was very happy to learn about home delivery. I couldn't believe that my order arrived in TWO days. I will definitely be reordering from Chewy.com.

    This website allows me to make sure my dogs never run out of food and it's so convenient and actually saves you money and so much time. I love that I can have piece of mind knowing I won't be running to the store last second to buy my dogs food.

  • My dogs prefer it

    By on

    I've been reading all the articles about what foods to feed my 2 new pups, 1 year and 6 months now and getting flustered with the all the choices and the scare hype. I wanted to start them on the right track but went through 2 highly recommended brands before I found one both like. I sprinkle Science Diet 1/4 to 3/4 to get them to finish off my first 2 purchases.
