We adopted a black lab last night from an animal rescue group. We do not know anything about his background except he is four years old and given up for adoption by previous owners. I imagine he was allowed on the couch at his previous home but we'd rather he not go on the couches. I provided him with a soft blanket and he also has a nice size crate with a flufffy mat. We've tried taking him off and telling him no but he just stares at us and jumps back on. I know it takes time to unlearn an old trick but is there a way to train him not to jump on the couch or do I just have to grin and bear it until he gets the message?
