The motion activated sprinkler gets my vote.
(Only because pellet guns are an undesirable alternative)
Soak the stupid walkers.
I pretty much have wussed out on the issue.
I know the dog walkers around here, and there has been at least a couple of times now where I have been outside and I see a woman whom I know and whom is a nice lady letting her dog poop my lawn.
She apologizes of course, and I tell her that’s okay don’t worry mine is a dog friendly lawn, which it is. I’m not going to flip my lid over it, I mean my dog does poop in the back yard and I pick it up with my pooper scooper, so I just pick hers up from the front lawn with the scooper as well.
I wish all dog walkers would pick up the poop with bags, that’s the right thing to do, but I know that almost none of them will, but I don’t want to start a war over it.
What I can control is what I do, so I pick up Isis’s poop from lawns that she goes on when I’m walking her, and I wonder to myself as I do if aliens were watching me from their UFO, what they would think of Isis’s loyal pet human :D
