Understanding Canine Urine Markings Dogs have their own scent-lines. Male dogs mark areas with less of their urine and many times more often than female dogs.
Females puddle a lot in squats, rather than squirt a little like the boys do.
The boys have to calculate how to make a bladder-full of urine go around the neighborhood so that there is enough for all habitual marking spots, and new ones that must be made over, or aside, the marks of others dogs. The boys also mark new spots that are needed if a new terrain is explored for the first time. Sometimes the boys run out of urine before their walkabout is over. Then they engage in shadow-urination. They also engage in marking for other reasons that only dogs know best.
