Dogs have a whole complex body language system. They also have a series of vocalizations. Barking can be due to many causes and can indicate excitement, aggression or even fear. I recommend to read and learn about canine body language so that you can recognize what the rest of the body is telling you. Best of luck and please feel free to post any additional questions.
