Getting your dog micro-chipped gives you the assurance that should your pet be stolen, it is more likely to be returned to you safe and sound. The best way to ensure your dog is returned to you should it stray is by collar and ID tag inscribed with your name and number.
All you need to do is turn up to one of the sessions; there is no need to book. A ticket system will be in place, so that everyone who has a ticket will get their dog micro-chipped.
Dogs should be at least 12 weeks old and have had all of their vaccinations when they get micro-chipped.
Coun Nigel Sherwood (Brigg & Wolds), Cabinet Member for Highways and Neighbourhoods at North Lincolnshire Council, said: "It is great that we are able to continue our partnership working with Dogs Trust to offer free micro-chipping for dogs in North Lincolnshire – saving their owners up to £30. As well as the micro-chipping, Dogs Trust is offering free health checks and neutering. This is a fantastic offer as owners would normally have to pay for these services.
“If you haven’t had your dog micro-chipped already, pop down to one of the sessions. It will save you money and ensure that your dog is chipped before it becomes compulsory.
“It’s important that you get your dog chipped – it can save a lot of heartache and enables your pet to be traced back to you should it be stolen. A collar and tag is still law and you must have an up-to-date ID tag with the dog owners contact details. This allows anyone finding a stray dog to contact the owner and reunite them.”
