WHY do dogs mark trees already marked by other dogs? By leaving a mark, a dog communicates its presence to its kin and gets an indication of what sex, size and physiological condition dogs have been here. In neutral territory, it is a message that the individual is also using it. On the borders of the pack territory, the mark means that the area is occupied; the tag of a dog from another pack on the same object is a sort of "boundary post." On someone else's territory, it is a challenge to its owners, a claim on it. Marks are sometimes associated with the assertion of social status and with the search for a sexual partner.
