That is so cool! I wonder how it would know where your yards ends.

It uses a thin loop of wire placed around the perimeter of the lawn and it this this wire for a boundary and a path back to its charging garage. Dogs tend to check it out (read as look and bark)for a few days before putting it on the ignore list.

Oh okk well that is very cool! My dogs would go nuts seeing this!

Thanks for explaining how it works, probotics=) Courtney, I agree; it's cool AND my dog would go nuts!
