Interesting comments in this thread.
I don't see how Elliott is responsible at all for this latest attack. He had his dogs boarded, the dog attacked whoever was handling him. That seems to me to be more on the facility for not taking proper steps to ensure everyone's safety.
I also don't believe that some breeds are more aggressive than others. Sure, pit bulls can be raised to be aggressive and be fighting dogs but they are a strong, powerful breed of dog. That is why they are picked. So, in the event they attack, they can do some damage. Some Chihuahua's are super freaking mean, but if one bites someone no one really cares because they can't do anything. I have a bull mastiff. He looks intimidating but if you come up to him he's likely going to roll on his back and wait for you to rub his belly. I could've raised him to be a jerk and attack people, but why would i do that?
