No, you are not stupid - dogs need trained in what is acceptable and not acceptable. I have a 100 pound Doberman I got from Dobie Rescue - apparently his first owner thought that that kind of behavior was "cute" too. I still can't keep him off the couch (or my lap) but at least I've trained him not to "jump" on anyone.
Whoa - am glad you trained him not to jump on people...bet the people are glad too! Glad you agree - and I think the poodle dog can be trained not to jump on all the furniture and onto people too....at some point. Thanks for the advice.
