The message went something like.
'This animal has been chipped with the ID-Tag database (Can't remember the name) You can contact them at... <Phone Number, Website, E-mail address>'
So yes, very helpful. In fact, if I scan my dog who is registered with Petlog, all I get is 'Yes, this dog is registered with Petlog.' You don't get the owner's details instantly, you have to call up. I believe it is part of the Data Protection Act. Imagine anyone with a scanner could access your pet's owners address simply by scanning a microchipped animal and entering their number online. Pet theft would go through the roof, and rather than being a deterrent, microchipping could quickly become the new tool to bribe owners of stolen pet dogs. I.E, Rover gets stolen, the thief scans him, and then has the owner's details immediately available to him in order to bribe/hold the dog to ransom.
The Dogs Trust story has nothing to do with different databases, it has more to do with failure of whoever dealt with that particular dog. The chip company has nothing at all to do with it. If it's not alerted that a dog with that microchip number has been handed in to the dogs trust, how on earth is it supposed to know? Nearly half the dogs in the UK are already microchipped.. do you think they should ring around the rescue centres every single time one goes missing 'just in case' the Dogs Trust hasn't bothered to check themselves?!
The pet log database actually sends an alert around to all chip implanters within a 30-mile radius of a missing animal. I would imagine the Dogs Trust would pay a lot of attention to these emails, considering they are getting a LOT of money donated to them from the public and rather than spending the money it must cost to re-home an animal, a simple scan and check with pet log could have had him back with his owners immediately. Although I'm sure this was just a one-off case where the Dogs Trust haven't checked, it is just such a shame that it has had such devastating consequences.
The exact same problem could have happened with a tattoo. The dogs trust could have seen the tattoo and not checked the database (Just like they have found a microchip not alerted the chip database, or not checked at all!) After all, if they could fail to do something so basic and blindingly obvious, I'm sure they could fail to report a tattoo, too.
Slightly less likely that noone else in the centre would double-check the tattoo number, but still.. you'd have thought it unlikely that the Dogs Trust would fail to check a microchip!
What I think needs to happen is routine scanning at the vets. The vet should scan the animal, enter the owner's supposed address (based on their records on file) and enter them. The actual owner's address wouldn't be revealed so no breaking the data protection act, however the system would flag up whether or not there was a match there.
