Canine etiquette

To be clear, I’m a dog lover. I realize dogs have to do their business outside and walks are a big part of their enjoyment. Why do so many dog owners think it’s acceptable to let their dog walk halfway into my front yard towards the house and do their #2 business? There’s a sidewalk that runs parallel to the street with a 3 foot or more grass parkway with trees. I don’t even mind if you use a couple feet off the sidewalk towards the house, but what makes you think it’s ok to come more than halfway up my front yard to let your dog take a crap?

I think I’m gonna follow the next one home and leave a surprise for them right off their front porch. Oh yeah, I’ll try to pick some of it up like they do. 🤦🏻‍♂️😁💩🤬
