I want to have Savannah re-microchipped. Why you ask? Well because her chip that she has now is registered to her previous owner, and i havent been able to get the info to be able to switch her chip info. we have had her 7 months now and we have no papers whehter it be AKC or her microchip info. I dont really care about the AKC papers but should anything happen and she gets lose i dont want her going back to her previous owner. So now my delimma. will a vet be able to microchip a dog that already has a chip in it? if so and the dog gets out who do they call?? I have a bill of sale for Savannah so if it ever came into question it is no problem, but i worry.
