I have an 8 month old APBT puppy. Today I noticed a spot on the back of his back leg about the size of a nickel that is raised and hairless. Its not hot or pink or discolored at all, just bald. I don't think its a hotspot, but Im not sure what it is. My Siberian Huskey had one under his chin a few months ago and I used Neosporin on it and it went away in a few weeks. The puppy was just at the vet a few weeks ago and since I live about 45 minutes away, I don't want to bring him in for nothing. Does anyone have any idea what it is? Have you seen them before?
