My ex girlfriend had the best damn dog I have ever been around. He was half German Shepard and half Golden retriever. Think blonde German Shepard with the long hair of a Golden Retriever. Beautiful dog and very protective of her. Super loyal and loving. That dog loved her. He was a bad ass dog. I remember bringing him a bunch of rib bones home one day from the BBQ place. Most had a little meat on them. I was going to just hand him one and she told me just to put the whole container on the ground. So I think he's going to to just take one and kind of gnaw on it like most dogs do. Nope not Chester, he proceeded to start eating them like you or I would eat pretzels. Unreal.
I saw her in the grocery store several months ago and she was showing me the scars. After the tornadoes came through there was some damage to her house. She went to a hotel for a night and then next day went back to survey the damage and get Chester. He was under the deck in the fenced in back yard. When she approaches him he attacks her. The only reason she is alive today is because a neighbor heard her screams and ran over with a shovel and beat the dog off of her.
After she had been in the hospital a few days the animal control lady calls her cell phone and said they had her dog and he was sitting at her desk just as calm and peaceful as he could be and ask her if she wanted to come get him. She was like, "um... No. I'm good."

My point being is that I don't know enough about any breed of dog to like them or dislike them, however all animals have brains just like we do and can freak out at any time and do something crazy.
