Does my dog need a microchip and an ID tag?

A chip is permanent ID, and a tag shows your phone number to anyone. Keep both up to date.

Short answer: yes to both if you can. A chip identifies your dog for life. A tag lets anyone who finds your dog reach you quickly.

How a chip works

The AKC says a microchip is a tiny radio-frequency transponder, roughly the size of a grain of rice, with a unique number. When a vet or shelter scans it, the number links to the owner's details in a database. Tags can fall off or become hard to read, while a chip permanently identifies the dog.

Keep details current

The RSPCA says a chip only works if your details are up to date. If you move or change your phone number, tell the database. Chipping rules differ by state and city, so check where you live.

Use a tag as well

A tag on a collar helps someone call you right away. See bolting out the door and emergency recall.

Get the right help

Ask your vet about chipping and how to update your details.
