Basenjis can be difficult, no question. But all of us who have them had a first one, and learned (or not!) to cope with their quirkiness. Some are definitely more challenging than others, so if getting a pup it is a good idea to pay attention to the temperaments of parents and siblings. Reading a bit on the forum and tapping into the wealth of knowledge that is out there should help prepare the prospective owner. I got my first Basenji on the strength of having read James Street's "Goodbye My Lady", and for what it's worth she was the most reliable and obedient Basenji I have ever had, perhaps because I went into it with few preconceptions and trained her as I had all my previous dogs. Here's Val back in the day.
The first picture is at the stables where I boarded my horse, the second is in my parents' backyard in the city of Toronto. Our yard was not fenced. Val doesn't even have a collar on, let alone a leash. I used to walk her loose in the city. She never betrayed my trust. None of my subsequent Basenjis have been as reliable! I guess she never got the memo about typical Basenji behaviour!
I am not suggesting that I was wise, but I didn't know any better and neither did she. These days, with the internet and forums, it's a lot easier to get help if you need it.
