All my puppies are microchipped. I have also pre-paid the registration. All the microchips must be registered. Sometimes pet owners forget to send in the registration, which can cause delays in reuniting pets with their owners. It is important to remember to send in your registration. It is equally important that you update your pet’s microchip information with any new phone numbers or a change in address. A microchip can’t do its job if the information on it cannot be traced.
