Compulsory MicroChipping for Animals

In the UK it is currently compulsory to MicroChip a dog and the government has announced plans to implement compulsory MicroChipping for cats in the future.


On the 6th of April 2016 it became a requirement for all dogs over the age of 8 weeks in the UK to be permanently identified with a pet MicroChip, unless exempt by a vet.

  • You must ensure that your contact are details kept up-to-date on a compliant MicroChip database
