My parents won’t let my dog on the couch... any ideas on how to convince them? She is 9 years old right now, and they always let her on the couch, but then when she was like 5, they stopped.I told them I would wash her weekly, and I even offered to buy a cover for our couch, so she wouldn’t be on the actual couch. They still say no. I know it’s unlikely that they will ever let her up on the couch, but any suggestions?
