Hey all... I'm looking for some advise. I'm posting this from my phone right now since I don't have computer access and my vet is closed till Monday. I noticed today that 10 month old Reggie has a big ball like blister hanging from his gums in the rear. It feels and looks like the size of a marble. I touched it and rolled my finger around it Nd he didn't flinch a bit, so I'm assuming it doesn't hurt. He hasn't none anything to my knowledge that could have caused this. Also, he's eating and drinking fine. I don't know if he bit his gun or what. I'm gonna try to attach a pic that I took on my phone. Any advise?
