Dogs are known to clearly show whether they are afraid or unafraid with the posture of their tails during a conflict.
How and why is this beneficial?
My limited understanding makes me feel that, in any social setting, disclosing whether an actor is afraid or unafraid would almost always be unfavourable for the actor. Is this incorrect?
Isn't it better for the less confident dog to try to bark out the stronger one and if it doesn't work then simply walk away, rather than broadcast that it is afraid of the stronger dog?
