My brother-in-law has a new lady friend and they want to introduce their dogs (don’t ask!). She lives in our city, he lives about 200 miles away. He asked if he and the dog could stay with us for the weekend. We’ve had pets ourselves but are now pet free. We don’t mind people visiting with their pets, but don’t want overnight stays because the house isn’t pet proof, there’s stuff around everywhere that a dog could get into, and we’d have to worry about leaving doors open. My OH told this to BiL and he’s not happy, obviously. Our city has plenty of dog friendly hotels that he could use, and that would actually be more convenient because we live in the suburbs. Are we being unreasonable about this?
