My sister recently moved to the same town as me but into a flat without a garden. She has a dog who only likes to do his business in a garden, not out on a walk. Since moving she has been letting herself into my garden with her dog so he can do his business in my garden as he won't do it anywhere else according to her. She does pick up after him but it all goes in my wheelie bin which stinks!
I had no problem with her dog using my garden when she would occasionally visit before but now it's become every day, 2 sometimes 3 times a day.
I've asked her to stop as I have young children who, now that the summer is finally here, want to play in the back garden and it just annoys me that all of the lawn area has had dog poo on it and as he gets a dodgy stomach fairly often, some of it is diarrhoea so my sister has been ripping up the grass in those areas when trying to pick it up.
Anyway, she's now very unhappy with me for saying her dog can't use my garden as his toilet any more and has said it's not a big deal and I'm overreacting and being difficult.
AIBU?
