Why do dogs urinate in every bush they see?

Answer 1

The dog is marking territory.

Male urine contains pheromones that are derivatives of a male hormone, testosterone, plus other unique markers. These natural chemicals can be detected by members of the same species and will direct them to alter their behavior. It's a signal to other dogs that "trespassers will be prosecuted." Some females urine-mark, too, though less frequently than males. This is understandable since no behavior is unique to either sex.

Some dogs have an obsession about marking their territory. After all, it is their heritage as pack members to live within a well-delineated territory. A territory contains all the commodities necessary to sustain the pack, including various valuable resources, including their mates and their progeny. Making it clear to strangers that they have crossed a line with respect to territory helps avoid unnecessary fighting.

Dogs use more than simply the odor of urine to define their territory. There are visible clues as well, including marks made on the ground by pawing and scratching.

For intact dogs (males or females) the solution is neutering. Approximately 60 percent of "altered" male dogs will cease urine marking within weeks or months of castration. Estrus-related urine marking will be abolished in virtually all females once they are spayed.
