  • Amazing food

    By on

    Growing up we fed Hills to all our dogs and they lived long, healthy lives. After trying many of the fad diets like Orijen and other “super premium” foods with our dogs now, we decided to go back to the trusted SD brand. Our three dogs have the healthiest coats they have ever had now. We will continue to stick with science diet since it’s obviously good for them and it’s a company I trust. They have considerably more energy and less poops.... not to mention they gobble it up.

  • Two Healthy Little Dogs

    By on

    Both of my two adopted dogs (children) arrived poorly cared for. One is small and one very small and they are now "pictures of health" (as per our wonderful Vet). We feed Science Diet, have for 2 generations of dogs, and are firm in our belief that it is good nutrition, apparently good taste, and reasonably priced. We appreciate Chewy's selections, great staff and pricing.

  • Science Diet is the Best

    By on

    My 5 Min Pins have been on Science Diet from puppyhood. They are healthy as can be for 9 year olds and have beautiful coats. Not to mention Science Diet treats their test animals very well and donates food to shelters.

    I’ll need to find a dog food with larger kibbles. This one is tiny...maybe for a chihuahua type dog. My vet tells me, the larger the kibble the better to help clean teeth My girl is only 10 p lbs, but she just swallows this one

    My rescue min poodle/min schnauzer/min??? loves this food. I'd always heard little dogs could be finicky eaters, but not the case with Hill's Science Diet Adult Small & Toy Breed Dry Dog Food. She has also maintained her weight nicely feeding it as recommended.
