To be annoyed by neighbour's dog peeing on the grass?

[weatherthorp]

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?

I'd plant something dogs don't particularly like the smell of, see if they're forced to move a bit further along!

Be careful you’ll get rsi from all the curtain twitching.

As someone who recently got screamed at for walking a dog on a piece of council grass you are being unreasonable.
It has absolutely nothing at all to do with you and you have no right to act like you have some kind of authority over it.

YANBU to be annoyed by it even if it is council land. Its kills the grass and its unsightly. The fact you can’t do anything about it doesn’t mean you can’t feel annoyed by it.
