I hesitate to fault anyone who is pushed to this point with a dangerous dog in close proximity. Too many animal lovers can't see the danger because they love their pet and think of their pet as part of their family. They think all animals are "special".
Pit bulls were breed to be thrown into pits with Bulls and later to fight other pitbulls. If you read about someone being mauled by a dog odds are it's a pitbull. If you read about some child being killed odds are it's a pitbull. People who own these dogs are imposing a big danger on their neighbors.
So some neighbor thinks they need to kill this dog, instead of going through some process that probably goes nowhere, it's hard for me to condemn them.
I met a lady today who was talking about the drug dealers who live near her who let their dogs run in a pack.
The local LE cites them> Big deal. It doesn’t stop them.
They are now considering more drastic action.
However, they are concerned that shooting them will result in retaliation. They are considering other options because of that.
