Pet Microchipping and Animal Welfare

Microchipping is a key tool for reuniting lost animals with their owners. Mandatory microchipping programs have been shown to improve return rates and reduce shelter euthanasia.

Key Facts

Microchipped dogs are more than twice as likely to be returned to their owners as non-chipped dogs, according to studies.
England mandated microchipping for all dogs from 2016; cats were added from June 2024.
Microchipping itself is a brief, low-pain procedure — the chip is injected under the skin between the shoulder blades.
Many lost pets are never returned because owners cannot be identified — microchipping eliminates this barrier.
Chip registration must be kept current — a chip linked to an old address is nearly useless for reunion purposes.

Welfare Considerations

Microchipping is a simple, inexpensive intervention with major welfare benefits. Lost animals face stress, exposure, starvation, and road mortality; those that end up in shelters face uncertainty and potential euthanasia. Every chip that enables a reunion is a welfare outcome — an animal returned to a safe, familiar environment rather than a shelter or the street. The minimal discomfort of the procedure is vastly outweighed by the welfare protection it provides across a lifetime. Keeping registration current and up-to-date is the part owners most often neglect — and the most critical to the system working.

What You Can Do

Ensure all your pets are microchipped by a veterinarian.
Update your chip registration immediately if you move house or change contact details.
Advocate for mandatory microchipping legislation in jurisdictions where it is not yet required.
Scan any stray or found animals at a vet or shelter to check for existing microchips before assuming abandonment.
