The microchip contains a personal, one-of-a-kind identification number, which is injected under the skin of your pet just like a vaccination. This provides a permanent, positive identification which cannot be lost, altered, or intentionally removed – a safe, simple, inexpensive way to protect your pet against loss or theft. Microchips have helped reunite numerous pets with their families. By microchipping and registering your pet in your name, it will greatly increase the chances of a safe recovery in unfortunate situations.
