Humans under stress exhale and sweat volatile compounds, which dogs' superior olfactory systems easily detect. As an emotional cue, this "chemo-signal" causes dogs to mimic caution or anxiety instead of excitement. This effect causes dogs to approach ambiguous situations more slowly, as if anticipating disappointment, according to research from the University of Bristol.
Scientific Evidence
Simple ways to reduce the risk
During food bowl tests in 2024, dogs were exposed to the scents of stressed versus relaxed humans. In contrast to neutral or relaxed scents, dogs that smelled stress odors hesitated longer near bowls associated with previous empty ones, indicating increased risk-aversion and pessimism. This implies that stress scents override dogs' natural optimism, which may impair concentration or appetite.
Behavioral Changes in Dogs
Dogs may exhibit symptoms like yawning, lip licking, panting, dilated pupils, shaking, or avoidance when your scent disturbs them. For instance, they can become destructive, hyper reactive, clingy, or withdrawn when they chew furniture. Paw preferences may change toward ambilaterality as a result of prolonged exposure, which is indicative of poor well being.

Dogs use the olfactory bulb to process human stress, which causes heart rate variations and cortisol spikes. Higher pet stress behaviors are correlated with owners job related rumination. Different dogs have different levels of sensitivity some adapt better than others but repeated exposure "burns them out" which hinders learning
