The other morning I am opening the drive gates and I notice a pile of poop on the other side of the gate. I was thinking that maybe a rival "doggie gang" was sending a message to my guys? My driveway is a hill and has 2 retaining walls on either side, so the dog had to purposely walk up it to leave his "card".
Maybe it was that rottie whose "territory" we were in last week or one of his homedogs? 
I think the intended insult to my "gang" was compounded by the fact that it was definitely a "kibble poop". 

I doubt dogs place their shit out on purpose.
They piss out their territory however.
Dog owners who don't pick up the shit after their dogs are POS's, and I'd like to see big fines for these scumbags.
...yeah, I've stepped into one or two pile of dogshits.
