Im thinking he has something going on with his mouth. What do you think the damaged tissue would look like or what would something lodged between his teeth look like? I want to examine everything before I bring him in. I have touched his teeth and it doesnt seem to bother him at all. So I think its his mouth itself and its hard to see with such a small mouth. I will take him to the vet, I just want to have a good idea of what it is.
I will look around and see if there are any cuts, splinters or pieces of stick stuck.
He's a chewer, so im guessing that's what it is.
