8 Awesome Facts About Your Dog’s Powerful Sense of Smell
Humans' sense of smell is tens of thousands to hundreds of thousands of times weaker than dogs'.
1 Amazing Sensitivity
Dogs are used in search and rescue, drug and bomb detection, tracking, and medical diagnostics due to their keen sense of smell.
2 Variety of Uses
Specialised nasal architecture helps dogs sense scents. Due to their vast olfactory receptor surface area, their noses can detect and distinguish many scents.
3 Unique Nasal Structure
In search and rescue missions, dogs can track odours over vast distances and find people trapped under wreckage because they correlate scents with memories.
4 Aromas as Memories
Dogs can detect minor changes in odours from people and objects. In tracking and detection, dogs can recognise people and objects by scent.
5 Personal Odour Profiles
Dogs can sense tiny odours, making them useful in identifying cancer, diabetes, and early epileptic convulsions in humans.
6 Ability to discriminate
Dogs can track scents hours, days, even weeks after the source disappears because scent molecules persist.
