    I bought this as a supplement for my dogs Hills prescription dog food. I have one dog on the prescription food and couldn't afford for all three dogs. Excellent results. All three dogs are losing weight.

  • My puppies LOVE this food!

    By on

    Our vet told us that our babies were overweight - one because of a thyroid problem. She recommended that we monitor their food or that we purchase a prescription food which was very expensive. I did some research and found this food. From the first bite, my puppies LOVED it! Usually, they are very picky about new food but not this time. In fact, my thyroid challenged puppy is now on a schedule and knows when it's time for her meals - and lets me know as well. They get their fill and are trimming down gradually. I highly recommend this food and its great price.

  • Finally, something my divo will eat.

    By on

    I have tried three other varieties of HSD, and I don't know why, but my skinny little chi mutt would only toy with them. Littler kibble bigger kibble same sized kibble, he'd move them all over the house but rarely eat them. This formula really does the trick. He will eat a bowl at a time and seems to be excited about being fed. I hope this continues because the bag is enough to feed him for months!!

  • getting to the perfect weight!

    By on

    Following the recommended feeding amounts helped my obese fur baby slowly get back to his target weight. It can take a couple of months but you'll get them there. Much less expensive than the one I could only purchase through the vet.
