That's why a lot of people get golden retreivers and labs. They're kick-back dogs that love everybody. Great with kids and strangers, usually.

Somebody on the Dogs 101 show said that since there's so many people comming and going at the White House, a teritorial towards it's owners type of dog isn't a good idea. Akitas, German Shepards, Lasa Aphsos, Chows, and others can be quite agressive towards strangers. That's the job they were bred for in part.
