Dogs bark at other dogs for a variety of reasons including communication, excitement, frustration, fear, territorial defense, attention-seeking, and social interaction. Barking is a natural form of communication for dogs, signaling emotions or intentions like playfulness, warning, or anxiety. For example, some dogs bark to say hello or invite play, while others bark to protect their territory or because they feel anxious or frustrated. Additionally, some dogs bark due to excitement or because they want attention or to express boredom. Barking can also be a response to being restrained on a leash or behind a barrier, where the dog cannot approach or interact freely with the other dog. Each bark type—whether high-pitched, low, or accompanied by other body language—provides clues to what the dog is trying to communicate.
