The Welsh Government has said all dogs in Wales will need to be microchipped by April 2016.
In a written statement to the National Assembly, Rebecca Evans, Deputy Minister for Farming and Food, said regulations governing the new law will be debated by AMs on October 20.
She said: “We are now working to bring in the compulsory microchipping for all dogs in Wales in April 2016 (this is in line with the date announced for compulsory microchipping in England and Scotland).
“My officials have worked closely with counterparts in England on cross-border issues because dogs are moved routinely between England and Wales.”
She added: “It is firmly believed that compulsory microchipping will have a positive impact because the traceability of all dogs back to their owners – and ultimately back to the breeders – will help to encourage more responsible ownership.”
