The dogfs eyes are designed so that he can see well in relative
darkness, has excellent peripheral vision, and is very good at
tracking moving objects.all skills that are important to a carnivore.
Dogs also have good depth perception. Those advantages
come at a price, though: Dogs are nearsighted and are slow to
change the focus of their vision. Itfs a myth that dogs are colorblind.
However, while they can see some (but not all) colors, their
eyes were designed to most clearly perceive subtle shades of
gray.an advantage when they are hunting in low light.
Dogs have about six times fewer taste buds on their tongue
than humans do. They can taste sweet, sour, bitter, and salty
tastes, but with so few taste buds itfs likely that their sense of
taste is not very refined.
A dogfs ears can swivel independently, like radar dishes, to
pick up sounds and pinpoint their location. Dogs can locate a
sound in 6.100 of a second and hear sound four times farther away
than we can (which is why there is no reason to yell at your dog).
They can also hear sounds at far higher pitches than we can.
In their first few days of life, puppies primarily use their sense
of touch to navigate their world. Whiskers on the face, above
the eyes, and below the jaws are sensitive enough to detect
changes in airflow. Dogs also have touch-sensitive nerve endings
all over their bodies, including on their paws.
Smell may be a dogfs most remarkable sense. Dogs have
about 220 million scent receptors in their nose, compared to
about 5 million in humans, and a large part of the canine brain is
devoted to interpreting scent. Not only can dogs smell scents
that are very faint, but they can also accurately distinguish
between those scents. In other words, when you smell a pot of
spaghetti sauce cooking, your dog probably smells tomatoes and
onions and garlic and oregano and whatever else is in the pot.
