^^^ Thats what seemed odd to me. Its not a matter of suspicion on my end so much as confusion. With that sort of experience and background, a random public forum would not be how I'd go about looking for a pup. I'd be asking around ring-side. Talking to handlers and checking out the dogs. Its sort of like how show/working breeders don't generally need to do much of any advertising to place pups, word of mouth on the field / at the ring will place them well enough in many cases... As well as people contacting them simply by seeking them out... You'd think an experienced show home would already have an idea of who they wanted a dog from, and to have contacted those individuals first... That is why I asked how long it had been since they had shown / finished a dog, especially since their previous breeders are no longer breeding / showing. I'm assuming its been a while and thats why they're not looking ringside first? (I could be totally wrong here).
That being said, OP... If it has been a while, please look carefully at any breeders that contact you. This forum does sadly get the occasional traffic from BYB and Puppy Mills, some of which do have titled dogs here or there in their pedigree, but none of whose offspring will likely do well (Kimbertal, for example). But they'll swear up and down their dogs are exceptional representations of standard, temperament, ect.
And instead of forums, maybe go to a show? That way you'll have the opportunity to talk to breeders, owners and handlers and get an idea of who/what you want. And you never know, you may run into someone you know that can help you out?
Best of luck!
