Getting a dog from a responsible breeder is definitely worth the wait and the work to find.
At my vet's office we are "the good basenjis". My vet actually sees several basenjis in their practice and the only ones they look forward to seeing are mine. The reason, mine have never tried to bite them, nor are mine shy about being handled, they are healthy. My vet was really upset to have a new client bring in her 8 week old basenji fresh off the airplane, it was terrified of people and had slipping patellas.
My mom's vet is considered "the" basenji vet in her area. The majority of his clients have dogs bought from the internet or a local BYB. He became "the" vet because so many of his basenji clients are being treated for a variety of hereditary diseases. He was absolutely shocked when she came in with hers for their first exam. First off, that she was able to provide him with OFA information for both of her dogs plus information on the health of their parents. Secondly, because they were both in really good condition, good muscle tone, no signs of the disorders he so commonly sees.
I have much the same experience with dog trainers. There are certain issues that they get used to dealing with because the pups that come to them did not receive as much early socialization. They are pleasantly suprised to see well socialized puppies with good communication skills.
So what I am trying to say is that good breeding shows.
