Overview of companion animal microchipping for identification, welfare benefits, and legal requirements.
Companion animal microchipping provides significant welfare benefits through enabling reunification of lost animals with owners, reducing time spent as strays, and enabling identification for veterinary emergencies. Mandatory microchipping of dogs has significantly improved reunification rates. Cat microchipping legislation reflects recognition of its welfare value. Database registration and updating are as important as the chip itself for welfare benefits. Microchipping education for new owners is a welfare priority.
