The last few replies have been great, thanks so much!
He is about 3.25lb and both testicles have dropped. They have been that way for about a month.
The vet believes he is fine to be neutered, it's just my decision.
I'll consult my Vet tomorrow on the extractions. I'm more worried about doing the extractions in one fell swoop to minimize the amount of times he has to go under anesthesia.
I don't think he's lost a tooth at just under 5 months yet
