im partial to labs myself. Ive also had a black and a white Shepard and they are amazing dogs. My wife is Korean. In Korea they have a dog called a Jindo. We are going to try to get one of those. They look like a cross between a Shepard and a huskie. Supposed to be incredibly loyal and intelligent dogs as well as great hunting dogs.
The L.A. police department brought them to the states a few years ago and tried to make them into police dogs. they said they mastered the training very quickly but found they lacked the focus to perform the job.
