  • 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.

  • Always Good

    I've had three labs over the last 30 years. I've always fed SD and they always like it. Bright shiny coats and lots of energy. Reliable but expensive.

  • Chubby husky

    By on

    After her second litter of puppies our dog was getting a little on the chubby side. After her spay it just worsened. She normally runs for 1 hour everyday with the other dogs but that didn't seem to cut it anymore. We gave her less food but then she acted hungry. We tried this food and within 2 weeks she was losing weight and wanting to eat less. And she loves the food, so the eating less isn't because of that. She will run to her bowl when she sees it coming her way. We were on hills r/d prescription diet but that was too expensive. This has worked the same if not better and its A LOT cheaper!

  • good weight loss

    By on

    Dogs love this, it smells great! In fact my big dog that doesn't need it insists I put a few on his food now or he throws a fit. The dogs I am feeding it to gobble it down and I am now able to feed my mini schnauzer a little more because he has lost all the weight he needs to. The Aussie not sure because I haven't taken him to get weighed yet and who can tell through all that hair.
