Your Dog’s Senses


A dogs’ hearing is one of its more pronounced senses as the dog can locate a source of sounds in six-hundredths of a second! Due to the their mobility, the dogs ears scan the environment for sound.  One ear may be used as a first indicator of sound, and then both ears are used to receive and process the sound that is heard. A dogs hearing is four times as powerfull as human hearing.

Taste and Smell

A dogs sense of smell is the most advanced sense as the dogs brain accomodates a large part to the interpretation of scent. The average dog has over 200 million scent receptors in its nasal folds compared to a human’s 5 million. The vomeronasal organ in the roof of a dogs mouth is used to capture scents related to sex. This apparatus sends signals to the limbic system, a system which is involved in emotional behaviour.

A dog does not experience taste in the way that a human does because it has one taste bud for every six that a human has.  Due to this limited number of taste buds, it is more realistic to think of a dogs reaction to taste as pleasant, unpleasant or indifferent rather than sweet, sour, bitter, and salty.


The first sense developed, plays a very important role throughout a dog’s life. Vibrissae, touch-sensitive hairs which sense air flow develop around the eyes, on the muzzle, and below the jaws. The whole body is covered with touch-sensitive nerve endings.


A dog has good lateral vision due to its widely spaced eyes, the dogs eyes are flatter, have higher sensitivity to light and can change shape less effectively than humans.
