Speaking of humping... Years ago, my Chiropractor asked how to get his Retriever to stop humping furniture, blankets, and house guests. I asked if the Dog was causing harm to himself or others. He said 'no' and I declared TO MY CHIROPRACTOR that happy humping was good for the Dog's back. On the other side, dominance, insecurity, nervousness, jealousy, and confusion about social status are some culprits I have seen in my practice and all are fix-able. AND THEN, THERE IS ECSTASY...
