temperature is handled by the
respiratory system. The hair covering
the body isolates the skin from
external heat. As the external
temperature increases, a dog's body
temperature also increases; a dog
whose body temperature increases
gets rid of this excess heat by sticking
out its tongue. This way, in spite of
their thick hair, they do not sweat on
hot days. Allah has given them such a perfect system, whereas we,
human beings, immediately sweat when we run even for half an
hour. But dogs never sweat even if they run for hours. Now that you
have learned this fact, you don't have to worry about dogs when you
see them with their tongues lolling out on hot days.
Also, if you think about dogs, you will remember that their bodies
are always very soft and bright. What gives this softness and
brightness to their skin is its oil glands.
There are some special systems within dogs' bodies. Thanks to
these systems, the paws of a dog are never hurt, nor do they wear
out and their claws never become irritated. As you see, our Lord has
solved even a minor problem of one creature by means of a
protective mechanism He has designed for it. Our Lord creates
everything in harmony. As this example also shows, Allah has
equipped all creatures with the abilities they need. Such examples
lead us to think and to realise the artistry in our Lord's creation.
