Original thread here.
The new bandaging is working very well. The vet came up with a very clever way to hold padding over the wound. She stitched several loops of very thin wire in a circle around the wound. She then packed padding over the wound and threaded gauze through the loops to hold the padding in place. Then she covered the whole thing with a stretchy bandage and stapled it to the skin above the wound and wrapped it all the way to his hock where she taped the bandage shut so it wouldn't flap around. The whole thing gets changed twice a week.
The biopsy results are back. It is cutaneous fibroadnexal hamartoma. (I can't find much info about this on the internet.) The good news is that it is BENIGN! The bad news is that the entire tumor was not removed so there is a possibility it could spread or grow again. I won't worry about that at the moment though. For now, I just want him to heal and feel well.
