We are picking up our 4 month old puppy this Monday (yay!). Here's my question.... I know that some breeders administer the rabies vaccine themselves before their puppies leave with their new owners. This boy is one of those cases and i've been advised by the breeder that he has received it and it will be a $20.00 charge when I come pick him up (not a problem). I'm curious, how would someone prove that their dog has received a rabies shot if the breeder gives it as opposed to a vet? Should I ask for some form of written proof I assume? I'd like to get a tag for Deuce's collar that shows he's had his shot (like the one the vet gives you)....am I able to do that now?
