When they spay and neuter, the vets usually check the teeth and pull any baby teeth still left. It's not a huge deal, but it can effect their bite if it goes on too long. My mom's shih tzu, Ritz, had 6 or 7 baby teeth pulled when he was castrated. He didn't seem bothered at all by it.

I am SO curious to see what Moki looks like now. Have you any idea how much he weighs now? I can't wait to see some pictures!
