Pets may not understand human language in the same way that humans do, but they can learn to associate certain words or phrases with specific actions or behaviors. For example, a dog may learn to respond to commands like "sit" or "stay" because they have been consistently paired with certain actions through training. While pets may not comprehend the meaning of words in the same way humans do, they can pick up on cues like tone of voice, body language, and repetition to understand and respond to human language to some extent.
