I was wondering if anyone has heard of the Platinum Performance brand. It has nutritional supplements for dogs, cats, horses, and even humans. I have used the Equine Platinum Performance as well as the Hoof Support formula with my horses, and the results have been great. (shinier coats, more energy, improved general health and well being.) It was recommended by my horse savvy vet. I was wondering if anyone has seen any significant positive effects from using the canine supplements. As it can be very expensive, I thought I'd ask before ordering it for my dog.
