We found some type of canker sore/cut on Sam's top gum last night while brushing his teeth. We sent a photo to our vet this morning. She said to keep an eye on that spot and if it's not healing within several days or if is bothering him (affecting appetite, etc), we should bring him in. It doesn't seem to bother him when we touch it and his appetite has bee normal. However, it seems the growth has gotten a little bigger tonight.
Any thoughts on what this could be and what caused it? He has been chewing on a new goat horn this week but I wouldn't think that would cause this type of cut.
