Earlier in the week Sam's mouth looked slightly lopsided, anyway, as his mouth always looks a bit strange (with his tongue always poking out!) I didnt think more of it. Then it looked like his chin was dirty (again thats not unusual because he dribbles sometimes) so yesterday I wiped it, like I would normally, only it didnt seem to be cleaning up this time. Anyway, today I noticed blood on that area, and it actually looks swollen too now. Its on his bottom lip to one side of his chin, if you see what I mean? It hasnt stopped him eating but he definitely doesnt like me touching it. So, its off to the vet in the morning.
