Actually humping is one of the signs of dominance as is any stance where one dog puts it paws on the back of an other. Your gal will come in heat when she's ready unless there is a medical problem. Have you had her around other gals that are in heat? Sometimes having them around the pheromones that are put off by the other bitches in estrus will bring them in. Meanwhile spend the time educating yourself cause you can never know enough about breeding these angels.
