What is a dog conveying when he makes rapid, high-pitched, repetitive barks?
A dog can tell us a lot by the way that he barks. Some barks are warning barks, while others are letting us know that it’s time to play. When a dog makes rapid, high-pitched, repetitive barks, it is usually a sign of warning or approaching danger, and is used to alert an owner of the situation.
What a dog is conveying with rapid, high-pitched, repetitive barks is essentially a call to action for any other dogs or people in its immediate area. This series of barks is a warning when something or someone is at a distance and poses a potential threat. The barks will change in tone and frequency as the person or object moves closer. The initial series of high-pitched barks is used in order to draw immediate attention to the situation, but not necessarily to scare away whatever is approaching.
The rapid, high-pitched, repetitive barks will change to lower-pitched, slower barks as the object or person moves into closer range. These barks have more of an aggressive tone behind them, letting the approaching person or object know to take caution. Once the person gets even closer, the dog will either growl if the person is suspected to be an intruder, or greet the person with a few more high-pitched barks if the person is familiar.
