I would say that sounds weird, if by weird you mean sleazy or as someone else said skeazy.
10,500 WOW, what kind of pedigree do the supposed parents have? (just curious if you have that info) I would think the pedigree wouldn't be all that great if it is the type of person to do all the work to breed a good puppy and not stick around for the outcome, but who knows with people nowadays??
And of course there could be the possibility of a tragedy in the family that made it the only way out, but you would think again that a good breeder would have other contacts than placing the dogs for sale in an open market.
