A dog wouldnt leave this airline passenger alone. Months later, a routine check-up explained its strange behaviour

A woman on a flight found herself repeatedly pawed by a medical alert dog, prompting its owner to explain that such behaviour could signal a potential heart problem. Following up with medical tests months later, she learned of her mildly irregular heartbeat. This incident underscores research indicating that certain dogs may be capable of sensing complex physiological changes, revealing their innate ability to detect hidden chemical signals in humans.
