Speaking of neighbor dogs. The Bull Mastif that lives behind me broke through my rear fence, then broke through my side fence to get to my other neighbor's yard and hump his bitch.
I came home from work and my side neighbor said "Your dog is in my yard"
"Really? Ok I'll go get her." I said.
I look over the fence and see the bull mastif going to town on his Huskey. Then I look over my fence and see my dogs in my yard. My little angels!

I think.
I tell him "That ain't my dog."
He says "well it came through your fence"
I repeat "That is not my animal"
I go inside my house and put my dogs in and inspect the fence situation. The side neighbor does the stupidest thing he could think of. He goes up to the dogs while they are still getting busy. He almost loses a hand when the male lunges at him, but is saved by the fact that dogs get stuck to each other.
I hear the comotion and ask him what happened and he says "I was going to try and get him off."
I said "leave them alone you can't do anything now."
After inspecting the fence I told him where the dog came from and he went to their house and they came to get the dog.
This weekend I'm building a new fence that the rear neighbor is paying for.
