Microchipping Dogs and Cats
Legislation
The Microchipping of Cats and Dogs (England) Regulations 2023 require that:
- all dogs in the UK are microchipped and registered by the time they are 8 weeks old.
- all cats in England are microchipped and registered by the time they are 20 weeks old.
'Registered' means that the details on the microchip must be recorded on an approved UK database.
If you buy or rehome a dog or cat, or if you change your address, you must also update your details on the database. If your details are not up-to-date, this results in the dog or cat not being properly microchipped in accordance with the regulations and you may therefore be subject to enforcement action.
A lack of a microchip, or incorrect details linked to the microchip, results in many stray dogs having to be rehomed as their owners cannot be identified.
Microchips
A microchip is a passive device no bigger than a grain of rice. Once a microchip is in place, it can be scanned and its identification code can be checked against the microchip databases to quickly identify the owner, allowing a stray dog or cat to be reunited with its owner quickly. A microchip is therefore a quick and permanent way of identifying a dog or cat, taking no more than a few minutes to implant.
Microchipping is a relatively simple process that can be undertaken by all veterinary surgeons or anyone trained to carry out the procedure. The procedure is no more uncomfortable than a standard vaccination injection. A few animal welfare organisations have also been offering free or reduced price microchipping for many years.
If you don’t microchip your dog or cat
It is an offence not to have your dog or cat microchipped and you can be fined up to £500 if you don’t comply with the legislation.
If a dog or cat isn’t microchipped, the local authority will serve a notice on the keeper requiring them to have the animal microchipped within 21 days. If the keeper fails to comply with the notice, they may be prosecuted and fined. The local authority can also seize the animal, implant a microchip and recover the cost of doing so from the keeper.
Once your dog is microchipped, you must still ensure that it is provided with a collar and tag bearing the name and address of the owner. Failure to do so is an offence and you can be fined up to £5,000 if your dog is in a public place without this information.
