Dog

Dog: Throughout history dogs have been guardians and companions of mankind. 

The dog will show it's protective nature and even sacrifice itself for the safety of its master. 

They have an instinctive nature of protection as well as affection and also has an instinctual need for the pack mentality. 

Being more inclined to be a part of a group than to run alone. For many centuries the dog has been used for hunting and protection.

In nearly all cultures the dog is revered as a faithful worker and companion.

There is a vast amount of research that's been done on the earliest known domesticated dogs and much controversy surrounding the findings.

Some relate to over a million years but the earliest actual evidence shows (using genetic DNA) to be around 40,000 years ago.

Despite these arguments the nature and meaning of the dog in this work has been stated for related consideration in the upcoming cognitions (concepts) and work.

Although another important point of the dog is its evolution from the original jackal, wolf, fox, to the domesticated, what you could call, more sophisticated breeds that we have

around the world today. It was also stated that a faithful dog was allowed to enter, into King Solomon's temple unless it was a female during her menstrual cycle.

That was not allowed. A woman during her menstrual cycle was also forbidden from entering the temple.

The reason being that the blood creates reactions with certain types of entities.
