Evidence for the relationship between man and dog
goes back to the very start of history.
Getting fed by man, made dogs loyal to humans.
But there were a number of reasons
to keep a dog in the Stone Age.
1. Dogs helped with hunting other animals.
They helped humans track animals,
flush them out of the undergrowth
and bring animals down.
2. Dogs acted liked babysitters,
protecting children from wild animal
while their parents would be away hunting.
3. Dogs gave off body heat,
warming up their homes
and acting like a blanket.
