Micro-chipping is a simple way to make sure your dog can be identified if it is separated from you.
Your dog must also always wear a collar and an ID tag with the name and address of its owner.
Compulsory Microchipping - Microchipping of Dogs Regulations 2015
From the 1st September 2015, all pups must be chipped, registered and certified.
From the 31st March 2016, all dogs must be chipped, registered and certified.
From the 1st September 2015 any pup must be microchipped by the time they reach the age of 12 weeks or before they leave the property on which they were born. The microchipping must be registered with an approved Database (www.agriculture.gov.ie/animalhealthwelfare/dogmicrochipping) and the breeder or owner must have a certificate from the database with the pup’s details and the owner’s details on it. From the 1st September 2015 it is illegal to sell, supply, buy or take ownership of a pup that does not have a certificate of microchip registration from an approved Database. This law applies to all dogs from the 31st March 2016. Any dog microchipped prior to the commencement of these regulations DOES NOT need to be re-chipped. The owner must however ensure that their details are stored on an approved Database that their details are correct and the Database will then supply them with a certificate confirming this.
