Dave,

Here is how I handled a problem neighbor dog...

I first approached the owner asking if he knew the dog was running loose (of course of knew). He said he would take care of it. He didn't. So I approached him again letting him know his dog was still being unruly. He was nice and said he would take care of it.

Last time I went to him with a copy of the county leash laws, explained to him that next time I would call the county attorney who would send him a warning letter for leash law violations. The next time the county attorney would send the dog pound after the dog - $60 fine to get his dog out, three times and the dog is put to sleep.

It was very tempting to just shoot the dog and put him out of his misery, since the owner didn't take care of the pet anyway. However, my lawer brother-in-law let me know I could get in some fairly decent trouble for that, IF caught.

Look up the leash laws in your county. I think just about every jurisdiction in the US has some sort of law stating that the dog cannot run loose off the owner's property.
