For all intents and purpose, we need to look at damage. In nearly all cases, save fluke things like catching a lip and tearing someones face open, newspaper headlines look for damage.
Big Dog = Mass damage and death
Medium Dog = Bite, or ouchy, or some stitches in extreme cases.
Small Dog = Damn! That little bugger just bit me! *shakes hand*
All dogs bite, good owner or no, and this is how I can prove it. Dogs sense fear. Somebody out there tell me I am wrong. Run from a big, or even little, dog and tell me the thing won't come after you. Provoked or not, the animals can pick fear up on radar and something in their genetics trips a switch.
My in-laws are complete pacifists, don't kill insects, and bought two dogs for their three youngest daughters. These animals were always fed, never abused, and loved like children, and yet they would attack people. Who did they attack you ask? They attacked people who were scared of them.
One was a boxer, a really sweet dog (and boxers have little teeth that can barely get through skin), and the other was a Lab, a breed known to be supper nice to EVERYONE. Now, when people would drive up to the house the boxer would get excited, something boxers do, and rush the car. Seeing this, the Lab would also rush the vehicle. If the unfortunate person had gotten out of the car, they were in trouble. What is a standard reaction when two large dogs run at you barking like mad? I would say at least a backstep, and more than likely real fear as you scramble for your vehicle. Once they got a whiff of this, the boxer would jump at the victim, as boxers knock you down (hence the name boxer) instead of biting because of their little teeth. While you were defending against the knockdown, the Lab would bite you (as Labs are not front paw strikers and he used the only other offense he had, that being his teeth). The Lab, the nicest dog in the world, would rip clothes off people, bloody fingers, legs, arms, and all the while assume it was a game. The Lab would be tearing you up and wagging its tail. The more the person paniced, the more the dogs attacked. It was awful, and these were dogs that would let babies pull ears and do whatever to them and not even bat an eye about it.
Large dogs create large problems, no matter who owns them. Any of you that have them, and I give you the benefit of the doubt that you have well treated dogs, would defend them by saying it was the victim's fault. They victims were 'on your property', or 'they ran from the dog', or whatever. I am not saying you are wrong, I am just saying you have to make excuses for big dogs because big dogs make bigger problems. Big dogs are scary, period, and if you react the wrong way around the best behaved big dogs you can still find yourself hurt. More hurt than reacting poorly around a beagle.
Plus, as was stated above, dogs are pack animals. They don't like other dogs coming into their territory, and the guy attacked by D-Lo's dogs was walking his dog. Maybe that other dogs marked that $4000 fence and the three pits took offense, or maybe they got exited just by another dog and human near them and fed off of each others anxiety until they chewed through the fence and went to town. Again, not an issue of bad dogs, but with dogs that size the danger factor goes up, as does the damage factor.
