OMG! I have to tell this story. A few months ago, Tyson (5 y/o, never a humper, neutered) walked out the back door to potty. As soon as he stepped out the door, he lifted his nose to sniff. I don't know what he was smelling, but he started "air humping" like he had no control over his body. He turned around to look at me...and had this terrified look on his face
Bless his heart, he just couldn't help it!!! LOL
