  • ‘’I’ve been putting this on my 13, almost 14yr. old dachshund/beagle mix’s food for a couple weeks now. She loves the flavor so there are no issues administering it. I have noticed her upper leg/thighs have regained some of their former muscle mass. That’s good enough for me‘’

    Luna

  • ‘’ I have two large breed dogs that are getting up there in age. Their joints aren't holding up as well as they were a few years ago, but they still love taking hikes and playing. So I try anything possible to buy some more time for them.. The have been taking these for a few days and seem to be enjoying them. They have a great mix of vitamins all older dogs should be getting! ‘’

    Cole

  • ‘’ I'd like to give this two stars because the taste was SO GOOD my dog jumped on the counter, chewed through the plastic and tried to eat the whole thing in one sitting. Not great. However, because he was so eager and put up such a fight, this is clearly pretty awesome-tasting stuff ‘’
