I'll be brave and say something first.
I don't know that I'd ever own a dog that had been bred for hundreds of years FOR fighting and attacking. Jeez, that's a scary thought.
But, I have and always will maintain that a HUGE part of a dog's demeanor has to do with the care it receives and how the owner uses it. Even a Pit Bull, when given plenty of love and affection and lots of safe play will be a sweet and calm animal. I've known Rotties and Huskies, PBs, and even a Doberman who were all just big teddy bears that wouldn't crush a fly. People that use thier dogs as guards, train them to attack, play very roughly with them, abuse them, tease them, ignore them completely or otherwise encourage "bad dog" behavior; will end up with dogs that attack people. Heck, my neighbor has a **Chihuahua** that they yank around on a choke chain, slap, yell at, and leave cooped up in their 1-bedroom apartment for ten hours a day, with one 5-minute walk; they act like they hate it. And it's a little monster...this little tiny thing will attack anything it sees! Now, Chihuahuas ARE yappy little dogs, but they're not generally mean.
Before any one goes "but...!!" yeah, I agree that in this case it probably wasn't ALL the owner's fault--but there's a certain responsibility that goes with owning a large dog, as well as in owning an animal that has been bred to attack or fight. You can't expect a Canary, or a part-wolf, or something to have the same emotional needs and care requirements that you'd give to say, a Shih-Tzu or a terrier. It may be a shortcoming on my own part, but I just can not believe that anyone who would keep an animal that size in an apartment building had the dog's best interests and well-being in mind.
I'm really interested to see how this trial comes out, since the couple that owns the dog is actually coming to trial. Where I live, I've heard about several of these cases--and the fight is always about destroying the animal, never about the responsibility of the owner.
p.s. everyone note I said "I believe" up there...I'm not meaning to ruffle anyone's fur...I know a lot of people just believe some dogs are just mean. This is just my opinion.
