I'm neither a lover nor hater of dogs, but I don't know much about them, hence the post.
My sister has a much loved dog, she had always had dogs. We see her out with the dog for walks fairly often and occasionally I visit my sister, but when she comes to me (more frequently because I have toddlers and she is single) our Mum looks after the dog (at my Mum's house) because of the toddlers and our small house.
This weekend my sister would like to bring the dog. I'm happy to see the dog, I want my sister to feel welcome, but I'm confused about dog rules. I don't really want the dog on the bed or furniture, but that is what she does at home.
Sister has dog friendly house and hard floors, as dog is (fairly!) a priority for her. I have woollen carpets upstairs and I'm worried about the dog's claws damaging the carpet.
AIBU: make sister and dog unconditioanlly welcome
AINBU: ask sister to cut dog's nails and/or keep dog downstairs
