Jillio an Jiro:
I actually think you're both right! In some cases, it is the breed and in others, it's the owners. Any animal is capable of becoming predatory; especially dogs. It doesn't matter if it's a pitbull or a cute little yorkie. Ofc, a person has more to fear from the pitbull. I also think that people have bred pit bulls to be even more predatory. You take an already aggressive animal and train it to kill, and you've got serious issues with that animal.
I personally wouldn't mind owning a Husky or Golden Retriever someday.
I had a golden retriever for a guide dog and she was one of the sweetest dogs I've ever known. Very intelligent, too. After she passed away, I missed her terribly.
One of my girlfriends had a husky for a guide dog. While she was excellent with her guide work, there were problems with aggression and excessive barking. Unfortunately, my girlfriend never did anything to stop these behaviors, so the barking and aggressive behavior continued to become worse. Her dog lived to be 15 years old and eventually had to be put down after an acute illness.
