Scanning of stolen dogs.

[MarcoPoloCX]

If a chipped dog is stolen and then sold on and is then scanned at the vets, and If the original owner informed the chipping company, would the scanner show that it's stolen.

When you scan you get the 15 digit number, you then contact pet log who give the details of the registered owner.
The RCVS are very clear about this our responsibility as vets is to the registered owner.
Actually for me in my area the issues are with cats that are randomly adopted and never checked for chips ( effectively theft) and it is discovered years later.
I scan all new dogs, but have found a stolen one.

That stolen dog, were the new owner told that it was chipped or not chipped when they bought it? And if they were chipped, were they given some dummy paperwork.

Macro sorry have not found a stolen dog. The correct paperwork should be the certificate with previous owner details on it signed to enable new owner to transfer details.
I suspect most stolen dogs go underground and are never seen by a vet.

If the original owner had reported the dog as lost/stolen to the microchip company, and the vet or whoever scanning the chip called up for the details then yes, it would flag up as missing or stolen. Obviously the owner has to have reported it in the first place.

The scanner itself doesn't show as stolen, this info would be on the database.

There have been a few missing dogs a couple of miles from me hence I'm curious about it. Dogs that are chipped but not found. Most vets scan new dogs but it's not mandatory. And also if they do scan is there a follow up call to see if the records match.

Also, sadly, if a dog is knocked down on a road and killed, many local authorities do not routinely scan bodies for chips when dogs are collected for disposal. Some do (and are to be congratulated for this) but it's not automatic. Even fewer do this for cats.

Although from April next year it will be mandatory to chip every dog. Hopefully this means that it will become mandatory to scan every dog every time it goes for a routine vet visit or is picked up by the police or warden. And that the police and wardens will have the power to stop and scan any dog at random to check that it is chipped. That would be good. It might put off these idiots that keep stealing dogs, if they think they might be stopped with the dog they've just pinched from someone's private property and be scanned.

Vets, the police, wardens and the micro chip companies need to work together and share info for this to be effective. Also linking the micro chip to the owner would help. ie when registering or changing details. You need to submit sonething unique to you like the national ins number.
