Hi Anthony, I haven't seen this before and don't know what it can be, but it could just be a cyst, or a mole, so don't think the worst before the vet sees it. Only he can diagnose it 100%, so it is a good idea to have it checked out, and he can biopsy it to find out exactly what it is, or he may know by looking at it what it is. It could be something minor, and if it isn't, then the earlier it is looked at and diagnosed and can be removed the better. I hope it's nothing serious, sending hugs and prayers your way that Scully is okay. Please keep us posted as to what the vet says, and try not to worry, but I know you will.
