Has he been neutered or are you planning on neutering him? Because I would take him to get the teeth out now because if the adult teeth are coming in & the baby teeth haven't fallen out yet, it could make all of his teeth crooked. If you plan on neutering him & haven't yet, I would take him in to get both done pretty soon. I had Lucky neutered & 7 baby teeth pulled at 7 months old & he did great! You wouldn't even have know he had surgery because he acted just like his old self as soon as he got home! Good luck!
