It’s very interesting to know how animals communicate among them. In case of dogs that are descended from wolves bark every time while Wolves bark only when they encounter any danger. Apart from dogs, the other animals that bark include prairie dogs, foxes, monkeys and deers.
Barking is of different types and each bark that comes out from dog has a different need behind it. Dogs are tamed well to bark when demanded by their masters and even while playing with ball, they bark in a joyful mood. The dog barking can be restricted by counter conditioning, psychotropic drugs and the surgical debarking.
