Sense of smell

Amazingly dogs have about 25 times more smell receptors than humans. They use this heightened ability to gain and share useful information with those around them.

Instinctively, dogs use their special ability to sniff out such things as food, danger, and even shelter. In today's case this was dinner… my dinner that was clearly MUCH more interesting than a bowl full of kibble…

You can't fool THIS nose!
