it is not unusual for dogs to be outside in any way
a neighbour should not have to limit his dog's freedom because of the dumb kid next door
neither the dog nor the neighbour are at fault
It's unusual to let a dog maul down someone's pets.
Also how is the neighbor allowed to have his dog outside, but OP not to have his cats outside? What is this a dictatorship? Dogs over cats?
Your logic makes 0 sense, is stupid and contradicting.
How about I lock you in a 4x4 cage with a bear and let it kill you? Obviously I won't get in trouble because "that's how nature works", bears will kill a human for it's own survival. Next thing you know I'm allowed to throw your family in a pit of alligators and let them die, but it's fine! "That's how nature works!"
No. It doesn't work like that. We have created a society and basic rules for a reason. The neighbor is completely at fault here. Stop being such a redneck and get your savage logic out of here. If you can't understand the basic principals of how to behave in the society of today, I can't help you.
