OTOH, I have a 50# 9 year old daughter, who likes walking around our sidewalks.
If stupid neighbors had a large aggressive dog which regularly got loose, I'd have a major problem with that. If it was an unstable pit bull, I'd be very tempted to take preemptive actions. But there are no such dogs in my area, so it's just speculation.
Now, if I lived on major acreage, I'd probably have a couple of dobies.
I suppose there are exceptions. Can dogs be insane, lol? Surely they can have brain damage despite the best breeding. So, if a dog is vicious and uncontrollable, then perhaps he should be euthanized. It would be hard to object to that. But I sure hate to see people calling for the elimination of an entire breed, especially one that is as well-established as the Rott and the Pit Bull.
