Facts About A Dogs Nose

By Keith Coddington

·         From a single drop of urine a dog can learn that animal's diet, health, sex, mental state, whether it is friendly, dominant or submissive.

·         The average dog has 200 to 250 million scent receptors in their nose.  Humans have approximately 5 million scent receptors.

·         The average dog has approximately 7 square meters of nasal membranes.  Humans have about one half of a square meter.

·         A dog's scent of smell is so effective at detecting extremely diluted odors that even the most sophisticated scientific instruments cannot measure these diluted odors.

·         Dogs can discriminate between different odors which makes it impossible to cover up or hide an odor with another.

·         Dogs see a 3-D image of odors which is much more detailed than what human's see with their eyes.
