text: The bark can make the dog for slightly different reasons and, like in humans, the tone and intensity determine what it is for a kind of shell. The dog can bark as well when it is happy as when it is angry or stressed. Barking is a normal dog behavior that can sometimes be a problem for the people in the dog’s environment. The dog naturally gives a shell in case of danger, for example, but too persistent barking can mean that the dog is stressed.
  Along with the shell, the dog, if in a leash, can simultaneously make an outcome. As a rule, it happens in the encounter with other dogs and is often misinterpreted as being tough and supportive. In fact, the dog feels insecure and threatened and needs the help of the person holding the leash to get away from the situation.
