I cannot imagine committing to buy a puppy without seeing the animal and if possible the sire and dam. OTOH, a rescue (or adoption of an older dog) is a different thing. My last two Basenjis came to me sight unseen, and turned out to be wonderful dogs, but the breeders I got them from wanted to place their dogs in an experienced Basenji home, and I only paid the cost of getting the dogs to me. One came by air, one was personally transported to me by his breeder. If she hadn't been happy with what she found I expect she would have taken him back with her when she left. I also had to commit to return him if ever I couldn't keep him. Good breeders care about where their dogs end up.
Thanks for the article on Dog Genome Project - I found it very interesting. I was trying to figure out the interactive Genome wheel. It has the basenji closely related to the Azawakh and rat terrier but I’m still trying to figure out the first wheel which has the basenji listed w/ black/grey starting point. As far as the PBS Dog Tales video - it’s very interesting - it’s season 47 episode 2 - I highly recommend you watch the whole thing (54 minutes).
