Dog owners must have their pets microchipped under new laws being introduced next year.
From April 6, 2016, it will be compulsory for all dogs aged eight weeks and over in England to be microchipped.
But current figures suggest that around 1.8m dogs are still to undergo the procedure within the next ten months.
A survey by the British Veterinary Association (BVA) shows that 94 per cent of vets in Yorkshire and the Humber believe a quarter of dogs are still unchipped.
John Blackwell, practising vet and BVA president, said: “As a member of the Microchipping Alliance, BVA pushed hard for compulsory microchipping of all dogs and we are very pleased that microchipping will be mandatory in every country in the UK by spring 2016. But with the vast majority of vets estimating that a quarter of dogs are unchipped there is no room for complacency.
“We hope that all the activity during National Microchipping Month impacts on the amount of dogs microchipped.
“We know there is a job of work to be done in fishing out those unchipped dogs and helping owners take action to ensure that they not only comply with the law but that they protect their much loved pet.”
The microchip, which is the size of a grain of rice, will need to be officially registered with an approved microchip database, which will hold up-to-date information about the dog and its owner’s contact details.
Huw Stacey, director of clinical services at Vets4Pets, said: “A sterile microchip is inserted painlessly under the skin between the dog’s shoulder blades and takes seconds to complete, meaning a dog can be in and out of a practice within a few minutes. A microchip is designed to last the lifetime of a dog.
“Microchips offer a quick, effective and permanent way of making sure your pet is always identifiable and that you can be contacted in the event of them being lost and subsequently found.”
