Nothing leaves here without a microchip with MY information on it. If new owners want a chip with their info on it, they can have a new one inserted, or they can add their information as secondary to mine that is already on the chip.
This is legal permanent ID as far as the AKC is concerned, and also for all health testing such as OFA, CERF, etc.
Is is proof if I ever need it that the puppy is the same dog as identified by the AKC number and paperwork.
Shelters/rescues who do not scan chips are in the minority. This is my personal insurance that if a dog I bred EVER ends up in a shelter or a rescue, that I as the breeder will be notified so that I can take responsibility for the dog.
I would say ABSOLUTELY YES, chip your dog!
