Brindles were very contraversial in this country when they first arrived. The Kennel Club wouldn't acknowledge the colour and it wasn't admitted into the Standard for quite a while.
One brave judge gave a CC to a brindle, before it was a recognised colour.
I admit I wasn't keen on it, but surprised myself in Germany when I judged their specialty, by finding brindles for many of my top winners. Heads were universally better in them and movement was (almost) back to true Basenji gait. Something rarely seen these days, anywhere. And I have judged in quite a few countries. . .
I put it down to the fact that, as they were very recent imports from Africa, humans had had fewer generations to mess about with them and they were still far closer to the old fashioned Basenjis I prefer !
