Skin the dog owner for it.
Ban the breed. Some dogs were not meant to live among us.
We live way out in the country and my neighbor brought home a Pit about a month ago. We have a little Chihuahua. I told him the first time that thing came across the property line, I was going to shoot it on the spot...absolutely no questions asked.
It wasn't a week later, we caught our 4lb Chi actually chasing the Pit out of the yard....almost funny. The problem with that breed is that they are so unpredictable. One minute they're scared of a little Chi and the next minute they're mauling a human....you just never know. I called the Sheriff's Dept. and filed a complaint. I told them the same thing I told the owner: I was going to shoot the Pit next time it crossed the line. Sheriff's Deputy showed up and we went and paid the owner a visit. Once again, I re-iterated to all that I would defend my property and family. He had a choice: chain it up or get rid of it. I also told him that if it broke loose and did any harm to any thing or anybody, I would sue him.....right after I shot it.
The Pit disappeared the next day......
