What is a dog’s primary sense?

In other words, which sense gives the most information to help a dog learn about his surroundings?

A.  Sight

B.  Hearing

C.  Smell

D.  Touch

The Answer:  C. Smell  As Alexandra Horowitz says in her book Inside of a Dog: What dogs see, smell, and know, “What prominence suggests, and what all science confirms, is that the dog is a creature of the nose.”  A beagle’s nose may have 300 million sensory receptor sites, just for smelling.  A human, by comparison, has only about 6 million.
