  • His Quality Diet

    By on

    My husband, a small animal veterinarian for 26 years, will feed our pets nothing but Science Diet. We pay full retail for Science Diet, even when a competitor offered to supply us with their product for free.

  • The holy grail of dog food!

    By on

    We have a Corgi and a lab/Pitt mix, both of them refuse eat literally any dog food except this one. They both love the small bites and it never upsets their tummies. Best quality! Worth the price.

    I've been feeding our 8 year old rescue Doberman this kibble for 3 years. He does great! Small bite keeps him from eating to fast and choking.

  • Love Hill's Brand

    By on

    For the past five+ years, our oldest dog had to be on Hill's WD Prescription brand dog food. It was the only thing his system could tolerate so all four of our dogs ate it. Sadly, our Buster Boy passed away last month. So we decided our remaining three dogs could change over to one of the other Hill's varieties. We tried three of them until we found that they like these small bites best.

  • Pet food, delivered. NO HASSLE ! No special trips to the pet food store...

    By on

    The dog food I get for my corgi is getting harder to find in this area... As I regularly use Chewy for the chews my vet recommends, I thought I'd try Chewy for dog food, at a friend's suggestion... It arrived on my doorstep in the blink of an eye as usual... GREAT service. And no, I don't buy this food just because there's a corgi on the bag!

  • Good product.

    By on

    We adopted a dog from our local humane society. I immediately put him on this upon a friend's recommendation. No problems transitioning to this food from whatever he was being fed before. He's gained some weight (which he needed); his coat is healthy and shiny. All in all, we're both happy with it!

    Buddy has been on Science Diet Healthy Development Puppy and now that he's a year old we've transitioned to the Adult Formula. Same great tasting bite size pieces (I even use them for training treats). Shiny coat and healthy teeth and bones.
