I tend to walk my dog in one particular park. Lots of dogs use it, and the owners are generally great, and friendly.
There are a few though who are starting to annoy me. They pay scant regard to their dog, who often is some distance behind them as they are glued to their phone screens. Another one "walks" his golden retriever and often I see him pottering along at the other end of the park - completely out of sight.
Needless to say there is a fair amount of dog poo that doesn't get picked up.
At times I've seen these dogs poo and their owners have been oblivious. I always call them over and tell them they have something to pick up.
What I want to do is rip they head off and shovel the dog poo down their neck. As this would get me in to trouble, would it be acceptable for me to simply explain that if they fail to keep an eye on their dog I will report them for fouling?
What would you do?
