I witnessed something that for me would spark a similar reaction. It wasn't at my house, so we are good, but...
I was driving to work this morning, and stuck in a residential area due to the city thinking that 7:00 am is a good time to do construction right next to a road that is the main "non-highway" path through town.
Anyway, this lady let her dog outside via her front door. The dog made a full sprint bee-line run to the neighbor's back yard (they houses are on a corner of a block and perpendicular to each other). The dog proceeded to "do its duty" about 2 feet from the bottom steps of their deck and run back home. By the way it played out, it seemed like a normal occurrence, and the lady didn't care that the dog wasn't in her yard.
1) I would want to kill that dog and then the neighbor
or
2) I would love to have that dog from time to time if I could get it to go to select neighbors and provide the same "service" for me
