Black Hactcin, the creator in Jicarilla Apache myth, creates a human companion for dog and teaches the man to run and shout.
.
“What else?” said the man.
Black Hactcin thought a minute. “Laugh,” he said. “Laugh, laugh, laugh, laugh.”
When Black Hactcin said “laugh” the fourth time, the man laughed.
The dog was very happy when the man laughed. He jumped up on him and ran off a little, and ran back and jumped up on him. He kept jumping up on him the way dogs do today when they are full of love and delight.
The man laughed and laughed. “Now you are fit to live,” said the creator. So the man went off with his dog.
