@antalioops:
The noises they make are unique & unforgettable! My Nala baroos for my husband almost every evening when he comes home. She has graced my only a handful of times. She has barked twice, to my knowledge. It is my understanding that Basenji's do bark. When the breed was being perfected in Africa for hunting, the hunters chose to breed the dogs that barked the least until they got what we have today. I am by no means an expert. I just read that about them…
I would probably disagree with that theory. I have read that their vocal chords are shaped differently, so when they do bark…it is more of a singular "boof"...instead of a "woof, woof, woof". This is pretty typical of primitive type dogs. I doubt that Africans spent much time selectively breeding dogs that don't bark...in that situation, if you were going to select for anything, it would be effective hunting...barking wouldn't really matter, in fact it would probably make it easier to find/follow them in the jungle.
