That's sad that you have some disrespectful neighbors, Yorkie24U.
At least you know to keep them away from the big dogs and other wild animals out there. I actually looked up doggy treadmills before, and they are QUITE expensive, if you can get them to adapt to a human one, perhaps your whole family can use it. I've never gotten Yoda to go on the treadmill myself, he's terrified when it moves (and it is a bit loud).
