Suicide puppies

So.. in an effort to tire these little monsters out, I take them for a bit of a walk around my backyard. They should follow me like little lambs, but not these guys. These guys run over to the wall by the pool and than launch themselves off the side onto the stone patio, nearly killing themselves. OMG.. they need to go home, or I am going to throw myself off the side of the wall and commit hari kari with them.
