Honestly I'd not give my credit card number or any other vital information like that in which, if it got in the wrong hands, could be used to really wreck my life. That's not saying I'd necessarily suspect the breeder of any bad intentions, however they would have to store this information somewhere, and that means it is possible that somewhere, somehow, someone else who shouldn't might have a means to get access to it whether it's by computer hacking programs or someone breaking in and stealing it. I certainly think there's nothing wrong with requesting regular updates and any address changes, but I think I would personally do careful screening to begin with, request strongly that the person stay in contact, and at some point have to accept that the dog is out of your hands and you have done all you can to ensure it has a good home with responsible owners.

I was in close contact with Willie's breeder until we stopped showing him and he was neutered. At that point other than occasional updates we didn't talk to her much. When I moved to Minnesota, he was 8, and I did not call up and tell the breeder. We hadn't been in contact for a few years by then anyway, and he was no longer being shown, was not a breeding prospect. She knew the caliber of people we were that we'd never rehome him. I just had so much going on in my life at the time, I didn't even think about it.

Now, those of you saying "it's no big deal" (at least as far as I can tell) are younger, and haven't lived on your own and haven't experienced being burned or the very real threat of identity theft. I'd suggest you read up on it a bit. It is serious and it is becoming more and more of a common crime: IDENTITY THEFT

All it would take is someone finding out that a breeder collects credit card numbers, and then finding a way to get a hold of them. That is why in America at least, Privacy Act laws are very, very strict, and I doubt that contract would be legal here.

If you are determined to go with it, I'd definitely take Lady's Human's advice and make sure with an attorney that it is legal. In that case, if you had people willing to hand over those kinds of things and take the risk, more power to you and I'd just hope you never "lost" any of those things in some way, that would be a lot to be responsible for. . Personally I just would never take the chance..

My 2 cents.. or perhaps it was closer to a dollar
