I am not an expert, but here is what I remember from when Alex was a pup almost 4 years ago. Alex was about that size and that age when he was fixed. If you are worried talk to the vet. They should care for baby as much as you do. I ALWAYS get the blood work when Alex goes under anthestic. I don't want any problems and that eases my mind a bit. As far as what kind of anthestic, I would have no clues. I remember asking that vet and I used what they recommended for the little dogs. I can't remember how he healed. I got it done on a Friday, so that I had all weekend to be with him. I was a reck all that Friday though. Hope this helps.
