How Microchipping Works

Dog and cat microchipping is a simple procedure performed at your veterinarian’s office. The microchip is about the size of a grain of rice and is inserted just beneath your pet’s skin, between the shoulder blades. The procedure is safe and feels similar to a routine vaccination.

Why Registration Matters

A microchip only works if it’s registered. Registering your pet’s chip with Petkey ensures you can be contacted right away if your pet is found, no matter which brand of microchip you use.

How to Register My Dog’s Microchip

Registering your pet’s microchip is the most important step after it has been implanted. With Petkey, you can register any brand of microchip quickly online, by phone, or by mail. This ensures your contact information is always linked to your pet’s unique ID.

How Microchip Lookup Works

Each chip carries a unique identification number. When a lost pet is scanned, the microchip ID is displayed. The ID can then be entered into AAHA (American Animal Hospital Association), the Universal Pet Microchip Lookup Tool (www.petmicrochiplookup.org) , to find the registry where the pet is registered. If your pet is registered with Petkey, we will be contacted immediately so we can help reunite you with your pet 24/7.
