A microchip is a radio-frequency identification transponder that carries a unique identification number, and is roughly the size of a grain of rice.
When the microchip is scanned by a vet or shelter, it transmits the ID number.
There’s no power source and no battery, and no moving parts.
The microchip is injected and placed under the loose skin between your dog’s shoulder blades and can be done by a qualified microchip implanter and your local vets.
Microchipping is strait forward, they feel no pain and its over in seconds.
It is now mandartory to microchip both dogs and cats kittens and puppies It's a legal requirement for all dogs in England, Wales and Scotland to be microchipped and wear a collar with an ID tag.
It's also the best way for your dog to be identified should they go missing.
