Pit Bulls, the dog that Muslims would accept.
For over a decade I have had several neighbor move in around me up here in rural Alaska with pit bulls, they let them run loose on my property, scares my kids to death.
One thing I have learned, you need a low velocity big fat hollowpoint like a .45 to put one down, two shots minimum.
9mm bleh, not much instant kill, 10mm passes right through unless its a head shot.
I swear next time I may build a whippet, something like a 20ga. side by side short barrel pistol grip, 00 and a slug.
Its out of control in America, this is one animal that really needs to be restricted or owned only by a trained and licensed owner.
Have you talked to these neighbors about your concerns?
How far apart are your houses?
You might consider for the sake of safety,with your neighbors help,
introducing the dogs and the kids to each other.
Or are the neighbors too far gone to associate with?
