My male 8 year old boxer has that condition where his gums are growing over his teeth. I can't remember the right term for it. The vet wants to put him out and fix this but I am so worried about him not waking up. I could never forgive myself if that happened. I guess if he was younger I wouldn't worry so much. He is healthy otherwise. Does the condition have to be corrected ? What would happen if it was just left ?
