Scent-inel

A dog's sense of smell is reckoned to be a thousand times more powerful than a humans'.  A dog's nose is highly adapted to  'taste the air' in its ability to retain inhalations even when they breathe out. The curious construction of the nostrils swirls the air around and each operates separately to distinguish the direction,  the distance and even the age of the scent particles that flow past. 

Here, as we sit high on the cliff Raki has picked up the smell of some walkers who have just come into view over the brow of the hill (no doubt she smelled them before I saw them), but she's also very aware of the fragrance of the chicken bones I surreptiously dropped over the edge for the gulls.

As we walk home she'll zigzag across the land reading the odours of the day just as we might riffle through a book or scroll down a mobile phone. Even her dreams will be olfactory.
