1 What is a microchip?

A microchip is a small electronic chip, around the size of a grain of rice, which is implanted under the dog’s skin and contains a unique number that can be read by a scanner.

The dog owner’s contact details relating to each number are logged on a central database, so should the dog ever go missing or be stolen it can be scanned by the authorities and returned to his owner swiftly and safely. It is vital that the owner takes responsibility for updating their details with the database should their circumstances change.

Why is Dogs Trust offering free microchipping?

Microchipping is now compulsory in the UK, which we have long campaigned for.

A microchip is the most effective way of ensuring lost or stolen dogs get reunited with thier family. We want to help as many people as possible comply with the new law by helping to provide the procedure free of charge.

3How do I go about getting my dog microchipped for free?

Contact your local vet. Alternatively find out where free microchiping events are taking place here.

How and where is the microchip implanted?

Using a specially designed implanting device, the microchip is injected through a sterile needle under the dog’s skin between the shoulder blades.

Will it hurt my dog?

No, it does not hurt the dog. No anaesthetic is required and the procedure should cause no more discomfort than a standard vaccination.

4How are the owners traced?

If a stray dog is found to have a microchip, the local authority, vet practice or animal welfare organisation will contact the national 24 hour database to find the owner’s details. The owner can then be contacted and reunited with their dog.

Does microchipping replace the existing collar and tag law?

No, your dog will still need to wear a collar and tag that states the name and address of the owner when in a public place.


2Do I have to pay to update my details?

Most databases do normally charge to update details. Please check with your provider for more details.
