We all tend to put our personal experiences in about a breed, be they positive or negative. But, for the most part each breed has it's own set of statistics on temperament, which are more aggressive, which are sweet, wonderful with children, great hunters, etc. The Lhasa is overall not noted for being wonderful with children and a little bit unpredictable.
Pit Bulls are identified as a negative breed. I use to come home from work and find my neighbor's Pit Bull on my family room sofa, he'd come in through the fence and through the doggy door. This guy wouldn't hurt a flea....I'd have to rub his tummy to get him to move off the sofa and get him back home. This was exception.
And it does depend on how each dog is raised and socialized. But, we should always keep in mind when approaching any breed that they are first and foremost animals and can revert back to what every breed is noted for
