Dogs possess a sense of smell that's 10,000 to 100,000 times more acute than humans, thanks to an abundance of scent receptors.
While all dogs excel at smelling, those with short noses, like bulldogs, have a bit less sensitivity to odors.
Dogs and humans smell differently. Dogs have a special pathway that sends about 12-13% of inhaled air directly to their odor-detecting tissue.
Just like other senses, a dog's sense of smell decreases with age, with changes similar to those in human olfaction.
Dogs have a unique organ, the vomeronasal organ, for detecting pheromones used in mating, communication, and bonding.
Dogs can sniff with each nostril separately, primarily using the right nostril for novel scents and the left for familiar ones.
Dogs can sense when humans are stressed, detecting specific chemicals in breath and sweat with high accuracy.
Dogs are being trained to sniff out diseases like cancer, predict seizures, and identify low blood sugar, offering less invasive diagnostic options.
Dogs excel at tracking and can pick up scents from long distances, making them valuable assets for police and search and rescue teams.
Your dog recognizes and loves your scent, associating it with positive feelings and social rewards.
