Dog and cat microchipping is a simple procedure. We inject a microchip, about the size of a grain of rice, beneath the surface of the animal’s skin between the shoulder blades. No anesthetic is required. As long as you keep your contact information current with us, you should never have to do anything extra to register your pet’s microchip. Home Again doesn’t just help reunite pets with their family, they also offer 24/7 Medical Hotline which includes Poison Control consultations.
