Sniffer dogs have an incredible sense of smell that's up to 10,000 times more sensitive than humans. Their noses contain up to 300 million olfactory receptors, compared to only 6 million in humans.
Their incredible sense of smell is due in part to the shape of their nasal cavity, which is longer and more complex than ours. This allows them to detect scents that are too subtle for us to notice.
Sniffer dogs can detect cancer, seizures, and even Parkinson's disease, thanks to their incredible ability to sniff out specific chemical changes in the body. Their accuracy is often higher than medical tests, making them a valuable tool in healthcare.
Their training involves exposing them to a wide range of scents, from everyday items to specific medical conditions. With patience and practice, they can learn to detect even the faintest whiffs.

Dogs use their sense of smell to navigate their surroundings and communicate with each other. They can even use their sense of smell to recognize their owners and distinguish them from strangers.
