Two squirrels in our yard have spots of hair loss on their backs and haunches. Not weeping or red, like mange. What I find curious is that the both have symmetrical loss around their eyes, which doesn't fit the fleas diagnosis from the vet I called. Of course I'm concerned about the squirrels, especially in the below-freezing temps we're having, but I'm also concerned about my dog. Is this something she can catch from them?
