To not let sister's dog use my garden as a toilet?

[YesterdaysQueen]

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?

I’m sorry did you say you asked her to stop? Oh no, babe you tell her to stop. Right bloody now. She needs to train her dog to drop his guts on his walks and not in your garden.

Dear God no! Your sister is a cf of the highest order.

Would she want you to bring your kids round to shit on her floor every day? Thought not.

I would be taking the dog shit and putting it into her bin. Ripped open.

I work with dogs all day long and have my own pet and there is no way I would put up with this nonsense. She’s being very rude.

No that’s gross! We have a dog and we don’t even let him use the back garden as a toilet (wee ruins the lawn and don’t like kids playing where there are potential poo germs).
He uses the front garden for emergencies and bedtime pee.

Are you sure she won’t continue doing it? Can you lock the gate?

No way. That's revolting. The dog will learn to go on grass elsewhere.
It's very intrusive of her letting herself in 3 times a day to your garden anyway. How very entitled of her.

This would be bad enough if you didn't have children. Ripping your grass up will damage your garden over time, as will the dog weeing all over your grass. Plus the smell in your bins.

I find it bizarre that she feels entitled to trash your home like this, and thats before considering your children who are expected to play in a garden that her dog shits and pisses all over multiple times a day. She's revolting.
