Tough Looking Basenji
Basenji are dogs who seems to be very hard to please. They have a serious looking face. Despite of that, they are highly demanded by people as they shed very less. They have fine fur coat which leads to less shed. It makes them highly hypoallergenic.
Dogtime.com rates them 1/5 for shedding.
They have great power of smell and sight, so they can be quite useful. But yes, even though they are adventurous, you still need to train them properly and patiently as they can be a bit stubborn. Well that face does tell you that.
