Hello. I have stated that my property accepts animals upon request and after accepting certain arrangement, as pets are not allowed in the house. there is a special room at the entrance and also a huge yard for the pet to play. There is a guest who appeared with a very big dog, without informing me so that at least I could collect items that easily break and fabrics that are sensitive. He took the dog in the house with him and will leave it there all day while he's out for bussiness. What should I do?
