So this showed up a couple days ago, I’ve been in touch with the vet and I can’t get there until Saturday. I’m keeping him somewhat isolated because I have a kid with a suppressed immune system and I don’t want her catching it if it is contagious. If anyone has any idea what it could be so I don’t go mad with the disinfectant that would be great. Obviously I’m not replying on anyone here to diagnose but just some idea until Saturday. It’s under his chin area, so when you lift up his head that’s where it is. Thanks.
