Microchips for dogs & cats provide the best form of identification. Every year, lost pets are reunited with their families because of microchips. Dog and cat microchipping is a simple procedure. A veterinarian simply injects the microchip, about the size of a grain of rice, beneath the surface of your pet’s skin between the shoulder blades. The process is similar to a routine shot, takes only a few seconds, and your pet will not react any more than he would to a vaccination. No anesthetic is required.
