Patty, you are a sweet, tolerant, nice person. I can see this from your postings. But age really shouldn't serve as a shield when we're talking about the serious business of selling or breeding other living creatures. 19 years of age is not too young to learn to take responsibility for your own actions. That's what I tell the freshmen I catch plagiarizing or cheating in my college-level courses – I've heard "she's 19 years old, after all" from well-intentioned parents, but I file the academic dishonesty paperwork anyway. Now plagiarism is hardly comparable to the process of establishing a kennel... but I'm jumping in because that statement just struck a chord with me.
Back to the subject... By all accounts, Miss P. wants to do things expertly; the tone of her Praireland Basenjis website (which I think you've read carefully) conveys just that. But what I'm seeing pointed out on this public forum -- in brusque terms, perhaps, but honest ones -- is that something's amiss. $1000 - $1500 is a lot to pay for a "pedigreed" Basenji of questionable temperament, no matter how much was put into her. It was too much to pay to begin with, and the financial loss should be taken as part of the "lesson" that it really ISN'T that easy to acquire/show/breed dogs. Puppies are not blank slates, even at the age of 8 weeks. Since the seller in question is rehoming her dog because of a situational issue that she has admittedly been vague about (i.e. dog nipping son, seller not having time to work with 9 month old puppy), I think there is legitimate reason to question how she has the time to raise the 8 week old puppy that she is requesting as a trade.
There's questioning, and there's judgment. I think the former is called for here, and there has been a lot of that, but I haven't seen any 'bashing' or insults, just what some might call "brutal honesty."
