From 6th April 2016 all dogs must be micro chipped and owners must keep their registered contact details up to date.
This applies to all dogs from 8 weeks old. Breeders having litters must have them chipped by the time they reach this age. Any one buying a pup of this age or older should check that the puppy is micro chipped. New owners must register their details with the database company when they buy the puppy.
