What Kind of Dog Is That? どの犬繁殖はそれですか？

Romeo and Marvin are in Hidden Falls Park. Romeo loves rubbing his morillo on the handle of his leash. Capybaras love marking with their morillos and anal scent glands Secretions from the male nasal glands are a complex mixture with up to 54 compounds for each male capybara. Every male has most of the compounds present but in significantly different proportions probably to aid individual recognition. So when Romeo rubs his morillo on something and another capybara comes along, the second capybara will be able to identify exactly who left the scent mark. We humans think we are so clever and so superior to animals but we couldn't begin to identify each other using our sense of smell and the complex brain activity needed to make this identification.

Scent marking in rodents is like sending a business card. It can convey a wide range of information. It can be linked to agonistic behaviour in ritualised contests over resources. Scent marks may be used to delineate territorial boundaries, or group membership, or individual identity, or social and sexual status.

Scent marking behaviour and the chemistry of the secretion are related to social dominance and this is particularly true with rodents for whom status signalling may be the most common function of scent marking. Scent glands are commonly sexually dimorphic. Capybaras are unusual among the caviomorpha rodents in having not only anal glands but also a nasal gland, both of which are sexually dimorphic.
