we can't fix the loose boards in the backyard fence from our side, they nail in from the neighbor's side. They nailed in some boards once but otherwise won't do anything; we do not know the landlord. The pit bull barks and runs around our yard and charged me once, but no one so far has been bit. On one occasion it came in through our dog's door into the house. They usually keep it penned on the side of their house but that fence is dilapidated and the dog either gets out or they let it out. If the dog breaks through to my backyard again and charges us, or comes in my house, can we shoot it, or do we have to let it bite us or maul/kill our chihuahua first before we're okay to shoot it? we do not want a lawsuit, the dog is not registered as vicious or dangerous that we know of.
