Shhhhh . . . , don't tell these people about basenjis. If they understood, and were smart, and had a sense of humor, they'd all want one. I've done conformation, agility, coursing, rally and pet therapy with my basenjis. I'd love to try tracking. Here's an article about my brindlewonderkid, Digital, doing Rally.
In addition to a top rally performace, Digital is a multiple best in field dog (coursing), a bench champion and was in the top 3 agility basenjis in the nation (AKC rankings) for 7 or8 years. I also have Jet the try-ing who has a piddly 16 titles to his name. (Diggie has over 30, so 16 isn't a lot.) I also have an up-and-coming superstar. Zest is 3 and with only her Sr Coursing title to her name, is a bit behind the curve, but she's just about to hit her stride. Her debut is here:
if you're familiar with agility, you'll see she does lack a little focus, but over all a very nice first ever agility run. Nice weaves, nice lead out, nice rear crosses. And she also does spins - right and left.
Also, just for comparison, in addition to the basenjis, I have a malinois (our second mali). We did agility with our first mali and the first agility dog in the house was a lab. My chosen breed is, and always will be, the basenji. Yes they are harder to motivate. Yes, they do keep the owner/trainer on her toes. Yes, you do have to have a relationship with the dog. But gosh, what thrill when everything comes together.
I think with that list you spoke of, there are too many variables. It's been around for a while. It was a survey taken by trainers. I wonder how many of those traners used old school methods, methods that rely on force to get what the trainer wants. Basenjis find jerk-and-pull methods offensive. Really, if you can't get your point accross without using force, they seem to think less of you and basenjis have little use for fools. I think the trainers that find basenjis (or any breed really) "stupid" aren't very talented or versatile. I find them a challanging and a blast.
(And as to the milkbones, my dogs wouldn't care. They have higher expectations. )
