Brainpower & Special Smelling Organ

Dogs’ brains dedicate significantly more brainpower in analysing smells compared to humans, making their scent analysis capabilities substantially superior.  Equipped with the vomeronasal organ (or Jacobson’s organ), located above the roof of their mouth. This organ detects pheromones, allowing dogs to communicate through chemical signals. It’s a vital part of their unique way of experiencing the world and their fellow canines.

Dogs Can Sense Your Stress and Save Lives

Your dog doesn’t just recognise your scent—they love it. But did you know they can also smell when you’re stressed? Dogs have incredibly sensitive noses that can detect changes in your body.

Beyond stress detection, dogs are proving invaluable in the world of medicine. From detecting cancers to identifying low blood sugar levels, their exceptional sense of smell is being harnessed to diagnose and even predict health issues with remarkable precision. One day, this life-saving ability might just change—or save—your life.
