When Luigi first came to live with us @ 3 1/2 months he was humping everything especially Bella our 1 year old spayed female yorkie. He was humping the little 1 year old boys I babysit. Well Bella put him in his place and he stopped humping her. And by repetitive and firm no's he has mostly stopped. When the kids come in, in the morning sometimes he gets a little exited and carried away and humps them but not too often anymore.
