To keep it, print it while it is open.
A dog’s nose has many more scent-catching cells than a human nose. This helps dogs notice smells that are too faint for people.
In the picture
- Scent receptor cells in the dog nasal cavity: a crowded patch
- Scent receptor cells in the human nasal cavity: a small patch
Examples
- A dog can sniff out a treat hidden under a sofa cushion.
- A search dog can follow a faint scent trail to find a lost person.
Key takeaways
- Dogs have far more scent receptor cells than people.
- More receptor cells help a dog detect weaker smells.
