Is your girl spayed? Some spayed females will hump, for fun, like a habit, not to show dominance.
Some unspayed females may show dominance like male dogs, they hump to tell ther other who is boss. Does your dog just climb up your leg only or does she do the whole movement thing? To curb this bad habit, some books suggest that your associate the behaviour with something bad... like a squirt of water in the face, or a rattle a can with some coins inside to make a loud noise or just plainly shove her off your leg and shout "NO" and walk away. My dog, a female does this to my male dog,.... My male is not neutered but she is SPAYED! I associate the bad habit with loud "NOs" and shove her off my male dog. Now, she never does it.
Willy, my beloved shih tzu (22 March 1994- 8 August 2005) May you rest and live happily in Rainbow Bridge with the rest. You will forever be deeply missed by all.

i used a water gun (pump action type) and sprayed my dog's body (never the head) when he tries to hump someone. now, all i need to do is bring out the water gun (with no water filled) and pump it ONCE and he stops his behavior and tries to hide.
