Whats funny is our dogs are allowed on some furniture and not on other things, and they all comply.
We never let Gunnar up on anything, so to this day he won't get on a couch or chair. He's allowed on the bed if we invite him up but he won't stay long. He doesn't even try to get on anything else.
Bruzer is allowed on 1 chair in the family room (MY chair!
) and he's allowed on my wife's chair if she's in it.
Daisy is allowed on the couch in the living room and she'll get in my wife's chair (even tho' she's too big for it now). She'll come up on my lap if I'm sitting in my chair. She's allowed on the bed with an invite, tho' she'll worm her way up around 4-5am and lay at the end of it.
None of them are allowed on the leather couch in the family room, and none of them get on it. I don't think we ever did any special training except to never let them on the furniture we don't want them on. If they put a paw up on something off limits, it was "off" and redirection.
