Jazz (5 months old) has just recently discovered that the couch is a comfy place to lay. I put some thought into it and decided that i will let her be a couch dog and would only make her move if I, or anybody, wanted to sit where she was. What I'm wondering is if there is any way I could teach her that our couch is okay but other couches are not? We visit family and friends houses a lot and I know some people don't want a dog on their furniture (she already scratched my parents leather couch). The best idea I could think of is to put a towell in "her spot" and remind her that it is the only permissable place to lay. Will this work or am I doomed?
