Dogs are extremely fascinating creatures and are true companions to humans.
Over the course of approximately 15,000 years, dogs have been companions to humans.
The beginning of this partnership can be traced back to the time when wolves would visit human encampment in search of food.
When humans first began breeding animals, they began by selecting the creatures who were the friendliest, most loyal, and most attentive to man.
Because of this, there exist a considerable number of distinct breeds of dogs.
For the same reason that everyone of us is born with our own unique fingerprint, the nose print of every dog is also one of a kind.
Each dog has its own distinct pattern of wrinkles and ridges on its snout, which can even be used to identify the dog.
