Communication
Dholes produce whistles resembling the calls of red foxes, sometimes rendered as "coo-coo". How this sound is produced is unknown, though it is thought to help in coordinating the pack when travelling through thick brush. When attacking prey, they emit screaming "KaKaKaKAA" sounds. Other sounds include whines (food soliciting), growls (warning), screams, chatterings (both of which are alarm calls) and yapping cries. In contrast to wolves, dholes do not howl.
Dholes have a complex body language. Friendly or submissive greetings are accompanied by horizontal lip retraction and the lowering of the tail, as well as licking. Playful dholes will open their mouths with their lips retracted and their tails held in a vertical position whilst assuming a play bow. Aggressive or threatening dholes will pucker their lips forward in a snarl and raise the hairs on their backs, as well as keep their tails horizontal or vertical. When afraid, they pull their lips back horizontally with their tails tucked and their ears flat against the skull.
