I really don't think iabu about the neighbours dog, but maybe I am (at least to some extent)?
We've moved in to a new build estate, to the left of us is a detatched house, then we are in a semi. As it's a new build all back gardens were separated with those tiny wooden fences, only used to highlight boundaries.
We knew the neighbours to the left before moving, and once we were both in they asked if it was okay to erect a full fence (it would go up one side of or garden and then across their drive). They needed it up for their dog. We agreed and offered to contribute to some of the expenses for the shared fence, they decline as the husband would be doing it himself.
On the other side (other semi) the couple offered the same as they wanted a dog. We paid for half the cost of the fence that goes up the side of our garden.
We now have three sides of our garden fully fenced (back and two sides), with access to our driveway being open. We aren't in a position to finish the fence until later this year.
Neighbours to the left frequently let their dog run out the house and into the street or in to our garden. I understand that dogs can sometimes escape but they make no attempt to get the dog back and just stand waiting on it to return. They also have a fully fenced garden to let the dog run about in but still allow it to do this.
Twice the dog has run in to my house. Once through the front door after DS opened it to come inside when the dog was running free (DS is 6 and didn't think). The bloody thing scared my two cats to death (one ended up on top of my wardrobe for hours).
It has just run in my French doors, which open on to the garden, and the owners have no fucking clue. They've just let the dog run out the house and it's come in with it's muddy paws all over my carpet. I understand that my garden isn't completely fenced in but surely that's no excuse for a dog to appear in the living room!? If the living room door hadn't been closed (keeping indoor cars indoors) then christ knows where it would have ended up.
I've spoken to then a few times and just get a "oh dogs" type response. Aibu in thinking that you keep your dog in your enclosed garden? Should I just accept this may happen if my French doors are open because we've not secured our garden yet?
