Winston..what is GSD? I hear you about the hair, but, like you say, YOU are the one cleaning!!
Aussies are an "average" shedding dog, extremely smart, loyal and usually great with kids. They need A LOT of stimulation (mental and physical) or they can become bored and destructive. They are "herding" dogs and may try to nip at your heels as puppies (in an effort to herd you!) but training will take care of that!
