Dogs seemingly bark in any situation, initially leading scientists to suggest barking had no function. However, dogs also vary the sound of their barks in different situations, so a bark at a stranger does not sound the same as a bark during a game of fetch. This variation has led to the hypothesis that barking is a form of communication with humans selected to benefit us. However, dogs are not the only animals to bark. This vocalization appears in numerous mammals and birds. In this talk I will discuss how investigation into other animals and the acoustics of the bark itself suggest that the bark is associated with a conflicted motivational state. I will also present new research testing these two hypotheses against each other.
