Young bitches, or those lacking confidence will often not go (urinate or defecate) away from home, this usually changes as John says once they reach sexual maturity, and when they are coming into or in season, to advertise their state. Some bitches will cock their leg almost like a male. My second youngest bitch started doing this once she had a litter (thereby raising her rank) and will mark over where her companions have peede, or other dogs marks.
