I think the myth of the "non-shedding" basenji comes from the fact that throughout the year, you won't see very very minimal amounts of hair coming off your B. Normally (when its not shedding season), I only see a few loose pieces of hair a day. As compared to my old room mate's dog who would loose handfulls of hair when you petted her.
The most noise my B makes is a bark-like sound when startled, or to greet someone coming home. And, when he is trying to get my other dog to play with him (he jumps around like a fool and does an imitation growl, imitation bark, and a-roos at her until either he pulls her out of bed or she gets up willingly)
