A microchip implant is an identifying integrated circuit placed under the skin of a dog, cat or other animal. The chips are about the size of a large grain of rice and are based on a passive radio frequency identification technology.
The microchip is inserted into the scruff of the neck in a quick and relatively painless manner, where it provides an inexpensive but permanent means of identification throughout your pet's life.
Every microchip has its own unique number which when registered with a protected database is linked to your contact details and is required by law to be kept up to date by the dogs keeper. If your pet is lost and scanned by a veterinary practice or shelter they can usually recieve permission to contact you directly or indirectly.
Microchipping is a legal requirement in dogs, but not cats – although microchipping of cats is also strongly recommended.
