What sad times we live in if this is necessary! I have to say that nobody I didn't know approached me for one of my studs however, not that if they had, I'd have been doing my own homework, basically re the background of the bitch before agreeing. My dogs were 'at stud to approved bitches only'. And that meant if, having checked, I didn't think the bitch would nick with my male(s), and even more I'd need to see the bitch (never mind the owners), then I declined the enquiry. All stud owners are 50% reponsible for what their studs might sire - and of course, it's ALWAYS the fault of the stud dog if the unexpected turns up

I understand how people might feel re strangers walking in, and I guess in some breeds taking precautions might be more and more necessary but again it's a sad reflection of how things are, if this has to be asked for.
When it comes to selling my puppies, I'd not risk asking for ID. Too easy to be accused to abusing Human Rights - I went by the pricking of my fingers in terms of whether or not I felt the people were okay to have one of my precious puppies!
"......and have done something similar in the past with someone who was interested in a litter my dog had sired and they wanted to meet the sire, we met in a local pub....they were 100% genuine. "
I'm not sure I'd want to be involved in something like that - I would be willing to take my dog to the owner of the litter, maybe. Most breeders who use outside stud dogs, have a photo of the stud dog they use which for most people should be sufficient - and if your dog is being shown, as mine were, he should be 'known' without needing to meet up with somebody interested in seeing him because he'd sired a litter...? The contract is between breeder (of the litter) and her prospective owners. Surely?
