Raindog is an expert on huskies, hopefully they will be along soon to give specific advice.

As a more generalised thing, as I want a pup to compete in working trials, I would be looking for a pup from parents or lines that have proved themselves in the working field, not necesserily in my sport it could be working trials, but also sheep dog work or competitive obedience, I would also be looking for the sire and dam to have a reasonable level of drive, but not over the top.

I am sure people who require dogs for different purposes are looking for completely different things.
