The thing to do is collect all the poo and throw it back on the offenders porch.
The first time..
“... collect all the poo and throw it back...”
I will admit to a not so nice “Mom moment”. Some years back, there was a woman who would allow her poodle to relieve himself on people’s driveways. I was returning from a shopping trip and saw her standing in the middle of my driveway and Fluffy doing the relieving thing. I actually had to wait to drive up my own driveway! Then she starts to walk away and left a huge pile for me. Okay.... here is where I had one of those “you lost your mind” moments. I stopped the car, picked up the seething mass in my hands and yelled, “YOU FORGOT SOMETHING!!!” and then threw it at her. The poop hit her white jacket and her white poodle. (My kids were laughing themselves sick). Not one of my better Mom days!
Not their car? I'll try to remember next time.
A few years ago, some gal used to DRIVE her dogs over to our street and allowed them to poop at will, and usually in my yard.
Hubby (usually the calm, reasonable one in our household)decided he’d had enough....one day, he scooped it up and carefully dumped it all over the hood of her car.
She never came back.
