Hope you can help..my male dog had some action a while ago..on the bottom part or edge of his top lip..there is a small wound that would not heal..had his Pendistrep Anti-B shot after...he is all in good shape and all scars is healed up,but this part looks like it is rotting or binding away..it is about as big as your thumb nail..never seen this type of thing before..it just stays like that..doesnt form a dry scab..stays raw ???? If you would like too see i can send a pic of it?
Anyone had such a problem before? Treatment?
