You can try. TRY is the key word. Use something like Neosporyn on the wound 3-4 times daily. Hopefully he won't lick it off for at least a little while. If it doesn't seem to be getting better or looks like it's getting worse, you need to take him to the Veterinarian.
My basset had a cyst that broke open on her left side of her. It stop beeding. What do we need to do.The size of the cyst is inch in half. She is not licking it. Just let it be or what do I need to do.
Disinfect it and wrap it up with a sterile dressing
