I'll second what John W, Ingwe and a couple of others have said.
Train early, Train often, extremely smart, loyal, protective mostly, and remember they were not originally bred as pets, they are working dogs and like to have a a "job" (more training). A half hour or so a day working with them might do the trick. For their size they can excel at agility and are most assuredly capable of championships in obedience.
And before I forget, find a responsible breeder. Like some other breeds, backyard breeders have a tendency to select for undesirable traits like aggression and size.
Good luck,
Geno
