Does Microchipping Hurt? What to Expect at Your Appointment

The short answer: it is quick, and most pets barely react

The implant itself takes a few seconds, and most pets react about as much as they would to a vaccination. Some flinch briefly, many don't react at all, and there is no ongoing pain once the chip is in.

The chip is about the size of a grain of rice, roughly 12mm long. No anaesthetic or sedation is needed, and once it is in, your pet can't feel it.

Where the chip goes

For dogs and cats, under the loose skin between the shoulder blades. The skin there is loose and less sensitive, and it is the first place anyone scanning a found pet will check, whether that is a vet, a rescue centre or a dog warden.

What happens at the appointment

Your pet is scanned first, to check there isn't already a chip. Your details and your pet's description are confirmed. The chip goes in, and your pet is scanned again to make sure it reads before any paperwork is done.

The implant is the shortest part. Most of the time goes on getting the details right, because those are what get a lost pet home.

How pets react

Temperament matters more than age or species. Confident dogs often don't notice, especially with a treat at the right moment. Puppies and kittens may squeak once and carry on. Nervous pets tend to react to being held rather than to the chip.

Helping a nervous pet

Pick a quiet room, keep other pets out until it is their turn, and have treats ready. If your pet tolerates it, some gentle handling around the neck and shoulders in the days before can help. And try to stay relaxed yourself. Pets pick up on it.

Aftercare

Very little. Avoid rubbing or brushing hard over the spot for a day or two, and glance at it over the following days. No bandage, medication or rest is needed.

A small soft lump where the chip sits can be normal. If you see swelling or discharge, or your pet keeps bothering at the area, ask a vet to look. This is uncommon.

Common myths

Microchips are not GPS trackers. They don't transmit anything and have no battery; they only respond when a scanner is held over them. Chipping isn't surgery either, it is an injection under the skin.

And the chip on its own isn't enough. It only holds a number. What gets your pet home is the database record that number points to, so keeping your details current matters as much as the implant.
