My two year old female shepard/hound/lab mix likes to rub her haunches on the leg support of my lazy boy rocking the lazy boy and my legs. We used to laugh at her, but now it seems she is humping the lazy boy and we do not want to encourage that behavior of rubbing against guests so we have recently told her NO when she begins rocking the lazy boy.....she had that same satisfied look as the dog in the video.......
