I'm sorry, I probably spoke out of turn - but over here most, if not all, breeders will encourage visits. My pack, even when we were up to 8, of which three entire boys and five nubile ladies, was always open to visitors. Now I no longer breed - anno domini - the least I can do is help wannabe owners to make up their minds. If people are geographically unable to visit me, I can always put them in touch with a breeder nearer to them.
I guess living on a small island has its compensations !
