Dogs rub their face on people mainly as a way to communicate affection, mark ownership, seek comfort, get attention, or relieve an itch. Their face has scent glands that release pheromones, so rubbing their face on a human deposits their scent as a form of marking territory and showing that "you are theirs." It is also a sign of attachment and trust, similar to how puppies nuzzle their mothers for security. Sometimes, dogs rub their faces on people simply to seek comfort, feel secure, or get attention, while other times, it may be to scratch an itch or relieve discomfort from allergies or irritations.
In summary:
- Marking ownership and territory by depositing scent
- Showing affection and attachment
- Seeking comfort and reassurance
- Getting attention and bonding
- Scratching an itch or relieving discomfort
This behavior is generally positive and indicates a strong bond between the dog and the person.
