My fiancé and I are getting married soon at his parents’ house, and everything is great except that my future brother-in-law and sister-in-law are insisting on bringing their three dogs along. Two of the dogs are old and sick, another is a young terrier who has a nose for trouble. We’re doing our own catering, so I’m not looking forward to cooking with so many dogs around. The two larger dogs also keen very loudly if their owner is out of sight. My fiancé’s family is acting like he and I are selfish for not wanting these dogs around at our wedding. A polite request to not bring them was met with a minor fit about how they didn’t have time to interview dog sitters and a threat that the brother-in-law would stay home if the dogs couldn’t come. Also these future in-laws are not married yet and are not going to have the dogs at their church wedding. There’s a nice kennel where they can board their dogs for the day, but the sister-in-law has said they will not go to a kennel. What can we do about this?
