Nomadic dog

For several years neighbors on the next street have allowed their dog (a Sheltie) to just roam the neighborhood, peeing and pooping in the yards of everyone else, not to mention getting our dogs whipped up by an unrestrained intruder on their territory.  Not only is it completely irresponsible for a pet owner (the next street has a lot more traffic that goes a lot faster), it is just not neighborly behavior.

Last year, my wife registered a complaint with the police department, and an officer went and spoke with them.  Nothing changed.  I called again today to register another complaint, and the officer was very sympathetic.  He told me this story (not exact quotes):

"I totally understand.  My neighbor does the same thing.  Just last night I looked out and saw his dog taking his umpteenth crap in my yard.  So I went out, picked it up, and went over to the neighbors' house and rang the bell.  I said to him 'your dog seems to like crapping in my yard more than your yard, so I thought that I should return this.  Where do you want me to put it?"

I think that I find the right person to help us.
