Teeth can easily be pulled, if I am not mistaken. I would suggest talking to your breeder before doing anything else, but just to make you feel better, you can see from some of the suggestions here that you do have other options, should it come to that...hopefully it won't. I don't know what your intentions for this little guy are (as far as your breeding plan, nothing negative) if you are intent on breeding or if you would be happy as a pet, so I don't know what kind of outcome you would be willing to settle for as far as how to advise you. Definately talk to your vet first, I do know sometimes it take time for the testicles to drop, maybe he just isn't a "man" yet!
