So, I was brushing Sebastian, and had him on his back when I noticed this wierd spot kind of near the base of his penis?? It's green and hard and about the size of a freckle or a mole on a person. We have a vet appt tomorrow afternoon, but I'm kind of freaked out now. I can't imagine what it could be? Ugh, things have been going so well the last few months...I really don't want there to be something wrong again
