Veterinarians reported that older dogs engaged in more physical activity after consuming Fortetropin® and resumed certain activities that were thought to have stopped because of age.

Not only is MYOS safe for your dog, but it’s safe for you too. We wouldn’t feed our dogs something that we wouldn’t be willing to eat ourselves. Read more about our clinical studies.
