Jethro still had an appetite and carried his Jolly Ball with him everywhere, so I figured it must not have been too extreme. My assumption was that he was losing his baby teeth and new ones were coming in. The soonest the vet could see him was one week later.
Fast forward to yesterday. He goes to the vet, gets sedated, the vet tech opens his mouth, and I see the reality:
The cut is pretty deep, as you can see in the above picture. The front part of his mouth was torn open, pulling his teeth forward. He had to have three teeth extracted.
Jethro actually does not have any of his permanent teeth yet. The three extracted teeth were all baby teeth. I found it surprising how long the roots were.
The poor little man will be spending two nights at the vet's barn. Luckily, the vet thinks that it should heal quickly.
