Frequency of Urination Related to Dog Body Size

Little dogs pee more often on walks

Scent marking is a common form of communication across a wide range of mammals. Although dogs can scent mark in various ways, they most often use urine, which is obvious to anyone who has watched dogs pee here, there and everywhere out on walks or during play time.

Urination, and other forms of scent marking, allow animals to convey a large amount of information in an indirect manner. That means that they can communicate without direct interactions. That has the advantage of avoiding the costs of social interactions, which can include stress, the energetic costs of interacting and potential injury. In many species, body size is closely correlated with competitive ability, which is why scent marking may be especially important to smaller individuals, who may be unlikely to fare well in direct encounters.
