Man neighbors suck sometimes. Opinions?

My good friend has 2 rotties. Biggest babies on the planet. But strangers are **** scared when they pull up in their car. As it should be.
My yard it 9 acres, if the neighbors dog craps in my yard thats fine, just not on my doorstep.

Other dog down the road comes in my yard and marks all my wheels, cant get close enough to kick his ***,they came over with him one day,i pointed at my dogs run,said i dont let my dog wander, perhaps you should do the same.

There are also laws about cleaning up after your pets,they obviously dont abide by them.
