You know, I'm surprised that I didn't get in on this thread from the very start, I know that picture very well, I may well be one of the people responsible for it being "out there". It's funny, the blog mentions that the picture is from the '70's… nope sorry, 1993 I'd say. The little tri female running in right wheel position (with her head down) was from my first (and only) Basenji litter. She was born June 22,1992. The names of all the dogs are written on the back of the picture but I don't know where it is. I've got 3 views of that Basenji sled team but the one you usually see is the best.
Sad news about Annie though, she was quite the person. First time I saw her was at the Canadian National in '91, she was gaiting (storming) around the ring and I remember thinking, "this woman is serious, don't get in her way". She used to do competitive weight pulling with her Basenjis too.
