She is too lazy to ever take it out for a proper walk so let's it poo in the shared garden.
The children can't play in the garden as there are hidden poo piles everywhere. Her husband is a violent aggressive monster and is likely to post the poo bank through the letterbox as the least aggressive reaction to any complaints so in a bit of a pickle over this one.
How do I approach this with already strained relations with this particular neighbour?
AIBU in thinking she should take her dog to poo somewhere else?
