Dogs were domesticated from wolves over 10,000 years ago in the Middle East as people started
to realize dogs' great potential in guarding and hunting. This is evident from ancient cave
paintings which often depict dogs assisting men during hunting. Today there are over 200 million
dogs being kept as pets with North America having the largest share.
The dog is not a pure carnivore. It eats fruits, vegetables as well as meat and should be
considered an omnivore. Its internal organs are similar to those of humans although externally
both species look very different. The body of a dog basically provides strength and speed. The
paws have pads which act as shock absorbers when they run or leap.
Dogs have excellent sense of smell because their noses have long smelling membranes. Their
sense of hearing is also much better than human beings. They are able to swivel their ears so as
to focus on the source of the sound. However, they do not see things in colour but in black,
white and shades of grey.
The average life span of a dog is tweleve years. The first year is equal to fifteen human
years, the second is nine and thereafter, each dog year is four human years. This means dogs age
much faster and live the equivalent of about sixty-four human years.
