Some of the behaviours that dogs perform are super cute. That confused semi-turn of their head or when they nuzzle into our bodies have charmed great affection from us. However, other behaviours can be quite embarrassing and borderline rude in the social circles of humans.
Owners will often try to suppress these instinctive animal antics without fully understanding that they are perfectly appropriate in dog speak. Dogs are still dogs, even though they have integrated into our domestic lives so well. Understanding why they perform certain behaviours should make it easier to know what is normal and what is not.
