What do the barking of dogs have in common with human language?

The barking of dogs shares several similarities with human language, particularly in its ability to convey emotions and intentions. Just as humans use tone, pitch, and rhythm to express different meanings, dogs vary their barks to signal excitement, warning, playfulness, or distress. Additionally, both can be context-dependent, with specific sounds eliciting particular responses from others. This suggests a form of communication that, while not as complex as human language, still serves important social functions.
