I live in a semi-detached house with a small hedge to mark the boundary at the front. NDN has a fence instead. A metre-wide length of grass goes along the length of our hedge/their fence, right next to the public pavement. I believe this grass is owned by the council. Diagram attached.
Multiple times a day, our NDN brings their dog out of the house, past their half of grass and onto ours for their dog to have a wee. The result is our side is covered with lawn burn while theirs is unscathed!
On the one hand I think IABU to be annoyed because that land is technically beyond our boundary and not owned by us (although we do care for its upkeep). But on the other hand, I couldn't imagine letting my two dogs do the same on their side without a care in the world!
I'm not going to mention it to them either way as I favour neighbourly relations over a dog pee-free lawn. But it still bothers me to see it... AIBU?
