My former neighbor had one that touched their electric fence (they think) in the back yard, let out a yelp, ran to the front yard and attacked his wife.

My friend had a very large male that at times would go nuts and you couldn't turn your back on him. If you showed any fear, you were his. He came at me one day and thank God I yelled at him and went towards him instead of away from him. He backed down and never challenged me again.

He did bite a few people and my friend had to shoot him.

Both people paid a lot of money for their dogs and they were fine looking dogs. All we can think is there must have been some in-breeding to make them unbalanced.
