My pet seems to know when I'm upset, even if I hide it perfectly. How is this possible?

Your pet's ability to sense your hidden emotions stems from their keen observational skills and deep understanding of your subtle cues, rather than solely energetic shifts. Animals, particularly dogs, are adept at reading micro-expressions, body language shifts, changes in tone of voice, and even your scent, which can alter when you're stressed. For example, dogs can detect cortisol, a stress hormone, through smell. This sophisticated perception allows them to infer your emotional state, even when you believe you're perfectly concealing it.
