[Rescuemomma]

haven't read the other comments - If I have a reason to put the dog under, I'll have it done while they're out, but if I don't, I'll do it anyway. With the little ones, my vet does like to inject some lidocane to numb the area a bit first and gives it a bit to work before doing the microchip, because it is a bit painful. That may be something you want to ask your vet about. My vet is the only one I've known to do that, I've seen and helped microchip thousands without any kind of anesthetic, local or otherwise.
