I have two Border Collies, brother & sister. My girlie does everything at high speed resulting in her grazing her paws. I decided to try Mushers secret not holding much hope that it would help heal and protect her paws, how wrong was I it’s absolutely amazing. Since using it Gyp has had no sore paws. Would highly recommend to anyone to use as a protective barrier on their dogs paws even use it on my other dog.
