MIL has a large, bouncy, long haired moulting dog- she is lovely but leaves a trail of hair in her wake! When we last visited (she lives 2.5 hours away) our 6 y old daughter (who is mildly asthmatic) needed her inhaler far more than usual. MIL is due to stay with us (along with FIL) in a few weeks and DH asked if she'd mind not bringing the dog as we are concerned it's affecting DD. She's taken umbridge and basically responded "if the dog can't go, we don't go" and also said a sitter would be too expensive. This is despite them regularly leaving the dog with sitters or family when they go abroad. The upshot is, she's now not coming at all. For context, we have a small poodle dog so I suspect she feels there's some hypocrisy - but she's hypoallergenic, doesn't moult and has never caused any problems for DD. MIL can generally be problematic especially when it comes to visiting us and this is the last in a long line of cancelled visits for various reasons (including DD's last two birthdays). I feel like she takes any opportunity to make an excuse not to come up and I find it quite draining / upsetting particularly on behalf of DH and the kids. AIBU?
