Didn't Jesse's dog Cisco kill his other dog (don't recall the name)? It was on one of the episodes of his chopper show..Jesse didn't seem none too upset about it tho. Not a big fan of the breed myself, IMHO I think they are too powerful and unpredictable. I'd be scared to let my kids run free at the shop with dogs like that around.
We have a very good-tempered 11 year old female Malamute-Husky. She's put up with all sorts of torment from my kids when they were little (not that we condoned such behavior from the kids) and she's never even nipped at them. Overall Keiko is a great family dog and nothing more. Her mere presence in the yard has kept many people from entering our premises...little do they know the only thing she would do is lick them to death.
In the end it all comes down to different strokes for different folks. Some like em passive, some like em big and aggressive, to each their own.
