"Spectacularly staged rescue videos get millions of clicks on social media, whether they are real scenes, cleverly edited clips or AI illusions. Psychologically, this is confirmation bias at work. People remember conspicuous dog behavior before an accident but forget all the times the dog reacted similarly without incident. The desire to believe in a special bond with one's own pet and its unique abilities makes belief in canine clairvoyance even more convincing."
"Dogs have senses that are far superior to those of humans. They hear much higher frequencies, are sensitive to vibrations, changes in air pressure and weather, and have a sense of smell that is around 10,000 to 100,000 times stronger than that of humans. Studies on epilepsy, diabetes and cancer show that they can detect the slightest biochemical changes in the body in sweat or breath, for example."
Spectacular viral rescue clips encourage belief in canine clairvoyance, but confirmation bias and selective memory explain many perceived premonitions. Dogs possess far superior senses: higher-frequency hearing, sensitivity to vibrations and air-pressure changes, and an olfactory system tens of thousands of times stronger than humans. Dogs can detect subtle biochemical and physiological changes in sweat or breath linked to epilepsy, diabetes and cancer, and they notice shifts in muscle tension, breathing rhythm and stress odor. Nineteen family dogs reacted differently to sweat samples collected shortly before seizures compared with controls. Assistance dogs respond to heart rate, breathing, stress hormones and VOC patterns, not supernatural forces.
