|  Dogs r smarter than most creatures. They r easy to educate. Well-educated dogs r sometimes used as watchdogs. A watchdog can render a creature that is 5 to 6 times bigger ineffective. It is interesting, though, that these dogs, which can bcum terrifyingly wild in times of danger, pose no harm to their owners.
In the face of a threat, they put their lives in jeopardy to save their owners & under no circumstances do they abandon them. The existence of hundreds of dog species of different colors & sizes is one of the signs of Allah's matchless creation. In the Quran, our Lord's unique creation is related as follows:
"He is the Originator of the heavens and the earth. How could He have a son when He has no wife? He created all things and He has knowledge of all things. That is Allah, your Lord. There is no god but Him, the Creator of everything. So worship Him. He is responsible for everything. (al-An'am: 101-102)
Let's consider the following: assume that u have neva seen a dog b4 & somebody asks u to draw a pic of one. Would u b able to accomplish this? Of course not. No one could do this. Bcus, we cannot do anything unless Allah provides us an example in nature.
But if they ask u to draw a picture of Allah, there is jus soo many signs u can draw about him. Drawing a dog itself is a sign of the intelligence in u which Allah has created for u.
Aeroplanes, for example, r designed in imitation of the flying systems of birds. Robots r imitations of man's body systems. However, our Lord has created countless species w/o any previous example: Penguins living at the south pole, lions - the kings of the savannah, dolphins, butterflies, birds and bees, etc. in short, Allah created all creatures.
Allah, Who has given all creatures various features, has also given dogs physical characteristic that make them different from other living beings. For example, dogs hav 42 teeth, that is, 10 more than human beings. This way, they can grind & break their food, especially bones, into pieces without difficulty.
Moreover, thanks to the special creation of their eyes, in darkness dogs hav better eyesight than human beings. They can perceive moving objects from farther away. Furthermore, bcus dogs can hear voices at frequencies beyond our threshold of hearing, they notice noises from distances four times farther away than we can. For example, a man cannot hear the extremely high-pitched sound of the dog whistle used to giv commands to dogs while dogs can hear it easily.
The dog's sense of smell is also very keen. The olfactory centre - the centre for smelling - in its brain is 40times more developed than that of man. For this reason, their sense of smell is superior to man's.
By means of all these abilities, dogs can sense the smell of prey, trace it & fetch a hunter's catch even if it is kilometers away. A sniff of something belonging to a person suffices for a police dog to find its owner. Those huge flabby-cheeked dogs the Saint Bernards, for example, can easily detect injured people stuck beneath the snow with their sensitive noses & rescue them. This extraordinary sense of smell that dogs have is itself a miracle.
Dogs also use their noses to breathe air. Passing thru the nose, air is filtered, warmed and moisturised and then it makes its ways to the lungs.
Unlike human beings, these creatures do not sweat to regulate their body temperatures, bcus there r no sweat glands in their body. Regulation of body 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 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 u hav learned this fact, u dont have to worry about dogs when u see them with their tongues lolling out on hot days.
Also, if u think about dogs, u wil remember that their bodies r always veri soft & bright. What givs this softness & brightness to their skin is its oil glands.
There are some special systems within dog's bodies. Thanks to these systems, the paws of a dog r neva hurt, nor do they wear out & their claws neva bcum irritated.
As u 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.
