Skin lesion

Siberian Husky has growing lesion that stayed with small crust. We are waiting to get in to vet. But this is growing. We are treating with Duoxo foam 2x a day

Hello!  Which bit of dog are we looking at here, and does it itch? None itchy bald spots could have causes such as demodex mites, autoimmune or fungal disease. Itchy causes may include superficial pyoderma,

different kids of mite, fleas, allergies and so on.   In either case, if the lesion is getting bigger then a vet appointment to differentiate some of these - and other - causes would be a good idea.
