Each microchip is programmed with a unique code
number and emits a signal on a specific radio frequency.
A portable scanner held closely over the animal's shoulders
will read the number.

The Toronto Humane Society works with a company that operates the database and recovery system, which is a vital component of microchipping technology. When a stray comes into the shelter, the first thing the staff does is scan the animal. If the stray is microchipped, the special number is read and phoned into the operators. A check of the database will reveal vital information such as the name, address and the medical history of the animal. This information is recorded on a registration form when the microchip is implanted and must be updated if the owner changes his or her address.

Is microchipping a safe procedure?

Yes, microchipping is perfectly safe. Some people are concerned that the chip might move after it has been implanted, however, a layer of connective tissue forms at the site. This anchors the chip and prevents it from migrating.

Why should I microchip my pet?

Traditionally, pet identification meant a collar and tags, but a pet that wanders or is stolen from its owner may have lost its collar, or had it removed. While The Toronto Humane Society strongly endorses the use of external identification, the sad truth is that 50 per cent of lost dogs are never recovered. A microchip is with your pet for life and can greatly increase the chance of recovery if it becomes lost.

Every cat and dog adopted from The Toronto Humane Society is implanted with a microchip. Staff in shelters and veterinary offices across North America can access vital information about your pet. The cost of a microchip is included in The Toronto Humane Society's adoption fee.
