Oh my! I see that these little Yorkie babies are humping freaks! My mother has a Lhasa (male) and a Shih-Tzu (female).... Max, the Lhasa, has never been known to hump anything! He's about 18 months old, but was fixed when he was about 6-7 months. Lewis is 14 weeks and seems to hump Tiffany (the Shih-tzu) everytime they're together! He doesn't hump his toys and such...but it freaks my mom out that he's humping her...or trying to, lol...
