Dog owners in the Deepings and Bourne are being urged to microchip their pets before it becomes law from April.
The microchip, the size of a rice grain, has a unique 15-digit number to help identify a dog and its owner.
From April 6, dogs must be registered with on an authorised database which are kept by vet surgeries and dog charities.
Coun Nick Craft, executive member for environment at South Kesteven District Council, said: “The vast majority of dog owners already have their pets microchipped, but those who haven’t it’s easy to arrange this with a quick appointment at a vets.”
“Some charities are also able to offer discounted chipping so there’s options available to ensure your pet is chipped by the time laws change in April.”
Permanent identification of dogs through microchipping helps reunite strays with their owners, tackle puppy farming and encourages responsible ownership.
Where a dog is transferred to a new keeper, the new owner must ensure any changes in the dog’s name or details are recorded.
