  • HAPPY DOG !!

    By on

    Started our newly adopted dog on this to help him lose weight. He will eat anything and everything in sight, and had gained several lbs since coming to live with my husband and me. This food gives him all necessary nourishment, as well as keeping him satisfied until time for his next meal. Our Vet is also pleased with his weight lose progress. Slow, but steady, and our dog is happy and contented with his daily dinner !!

  • Never Fails

    By on

    I love this brand. Typically when you switch from puppy food to adult or from brand to brand, there is a bit of slow transition. But with Hill's science, from puppy to adult, did not require a transition. I forgot to order food and I was running out quick. My two large breeds eat a ton. So when I received the adult food, the Hill's Science puppy was out. Just in time! I was a little worried about their bio-habits; meaning soft-serve to watery. But I didn't have to. Serving them the Adult Hill's Science did not effect their Bio-habits at all. And! The dogs love it.

    I have my German Shepherd puppy on the Hills puppy food for large dogs and she loves it better than Purina puppy food I was shocked. I know that labs gain weight really quick so I got the light for my Labrador and she loves the food both are healthy and happy.

  • Great stuff

    By on

    I switched to this dog food more than 25 years ago because I had a dog that needed a low fat diet. It was a life-saver, in fact. I have fed my dogs, no matter their age or breed/mix, this dog food ever since. On a few occasions, I tried weaning them off this & onto something else -- I always went back to this and have never regretted it.
