Canines bark in order to communicate with other dogs and humans. It does not have a meaning like words in human language, but it symbolizes a sort of communication that reports the emotional condition of the barking dog. Dogs and humans (even youngsters under the age of five) can sense these changes. When they see or hear their owner coming home, for example, they will stop barking. Dogs also use their barks to ask for food, water, and other services. If you give your dog something tasty to eat after he has been barking for a while, he will probably stop next time he starts to howl. If he is thirsty, then give him some water. He will most likely stop barking if you take these things away from him. Some dogs may only bark when there is a threat involved, such as when someone enters their property or approaches their house. These dogs will stop barking once the danger has passed. Other dogs may continue to bark even after the danger has gone. These dogs need attention and care; otherwise, they will suffer from stress-related health problems later in life. Barks can be used by dogs to show anger or distress. Sometimes they may even be used as threats. Hearing strangers approaching, for example, may be enough to make a dog guard its territory or warn off intruders. However, this response should not be misinterpreted as aggression.
