No, I have never done it. My labs have never tended to wander and I never figure they were anywhere they could be stolen. Probably not a bad idea though. I'd be sick if our was ever lost.
Funny thing about looking for the dog. I did the same thing the other day. I thought she walked into the woods and was looking for he calling her. Just to find out my daughter saw her and called her in the house when she was out of my sight and before I started looking for her.

I don't see what good it does if your dog gets stolen. Its not a tracking device. The person who stole your dog would have to take it to the vet, ask them to scan it, and then call you and tell you he stole your dog. Lol, the only benefit is if you have a dog who runs off.
both of mine do... but as mentioned before, they're not tracking devices. they're just RFID tags that are inserted under the skin to ID dogs that dont have any other way to ID them. if the dog ends up in the wrong hands, they're useless.
There is no panacea. If the person in possession of the dog does not want to reunite said animal with you then there is no way to get them to return it. I just figure that I should make it as easy as possible for whomever has the dog to do the right thing. Kind of a corollary to "Locks are to keep honest people out." Personally I hope it never has to come into play, but that's never a good strategy.
