There are approximately 190,000 dogs in Wales that would need to be microchipped, if it becomes compulsory. There are an estimated 450,000 dogs in Wales and it is estimated that some 58% are already microchipped.
RSPCA Cymru believes that compulsory microchipping will help make it easier to identify the owners of those dogs that have strayed or are being mistreated, neglected, abandoned or lost. The Welsh Government has announced plans to have all dogs in Wales microchipped by 1 March 2015.
