Dr. Doug or anyone-Jesse's skin problems are back-questions

So far not really itchy. It's just in one armpit at this point. He's chewed a little bit but not much. Heading to the vet tomorrow for Clindamycin (he can't handle much else) to ward off any infection. We still have a foot of snow on the ground and have had sub-zero temps lately. Highly unlikely anything is growing just yet but some of the hardier trees maybe.
