We offer HomeAgain microchip identification. A microchip is a device that is about the size of a grain of rice. The chip is implanted in between the shoulder blades for a universal location. Microchipping your pet is a procedure that can be performed at any time and at any age. HomeAgain also offers a variety of services once the microchip is implanted. The most important part of microchipping your pet is activating your chip through the company that the microchip is purchased through.
