Dogs interpret human emotions such as worry, anxiety, fear, anger, pity and nervousness, as weaknesses and they do not listen to these emotions. Dogs listen best to someone who is calm but firm in their approach. They use their sense of energy to determine who should be the leader of their pack. The being with the strongest and most stable energy is the one they look to, be it themselves or another being around them. While you can hide your emotions from another human, you cannot hide them from a dog.
