Anyone know of a way to prevent a dog crapping on my path out to the garbage cans? By the size of the turds, there are at least two different dogs shitting where I walk to take my garbage to the bins out in the alley behind my place. It's right behind a motel, so I doubt it's just the same two dogs and two owners all the time. Besides, I've never seen an actual dog/person out there doing the deed, so I can't chase them away. The little patch of grass and weeds is the only one along that block of alley way, which must be the reason they like doing their business there so much.
I don't want to hurt the dogs (it's not their fault), but I'd definitely like to set a booby trap for the owners. Which, alas, is probably unfeasible. (Unless...oh nevermind...that might get me trouble. Unless...)
So, I'm thinking some sort of scent deterrent. I'm wondering if I, myself, pee all around that patch of grass, would that keep the dogs away? I doubt it, but I'm drinking some beer right now and working up some liquid defense.

Probably not the way to go about it, since I'll be pissing mostly water.
Home made hot pepper tea, maybe, sprinkled on the grass? I don't care about the grass/weeds. It's a wasteland back there. I just don't want to step in dog shit when I take the trash out in the dark.
