It's thought of as "cute" to some because our dogs are so little but true...I'd hate to see a Great Dane getting it on with a couch arm.
It can also be a dominance thing. My mom's spayed female Maltese, Lily, has her humpy care-bear that she loves dearly.
But, be careful how often and how much Simon's allowed to play with Molly. Wasn't it just recently someone posted about how their yorkie threw his back out from humping too much and the yorkie was in pain.
