We went to puppy class last night and during the five minute free time at the end of the class a pug boy 16 weeks was playing with lady and kept lifting his back leg and getting excited he didn't get his lipstick out. The owner of the pug pulled him away from lady. I thought that this was strange because i thought that pups would be 6 months before all the sexual behaviour started? Do i need to keep lady away from the males in the class? She didn't seem bothered just lied on the floor. And was playful with all the pups in the class chasing them about. anyone have any advice.
