Yudhisthira's Dog (Mahabharata)

The Indian (Pariah) Dog is considered by historians to be the first truly domesticated dog. And one is featured in the great Indian epic Mahabharat. 
The closing chapter narrates the tale of King Yudhisthira and his brothers (The Pandavas) making a pilgrimage to their final resting place. 

The Pandavas were firm in their resolve to renounce their Kingdom and began the ascent of a mountain as part of their final journey. Yudhisthira led the way followed by Bheema, Arjuna, Nakula, Sahadeva and Draupadi. A dog also accompanied them through their journey.

The first one to fall along the way was Draupadi (Yajnaseni). “Why did she die first, Yudhisthira?” asked Bheema. “Was she not virtuous, possessing a good heart?” Yudhisthira replied without looking back. “That is true, but she was more attached to Arjuna. That was her failing.”

The next to falter and collapse was Sahadeva. “What was his failing, O Yudhisthira?” cried Bheema. Yudhisthira continued walking without looking back, and replied: “Pride in his intelligence was his failing.”

Next fell Nakula. “What wrong did he do, O Yudhisthira?” wailed Bheema. Yudhisthira spoke, without looking back: “He admired his own good looks. That was his failing.”

Arjuna collapsed soon after. “What wrong did Arjuna do, O Yudhisthira?” cried Bheema, overcome with grief. Yudhisthira was unmoved and kept walking: “He was brilliant but conceited and over confident. That was his failing.”

Bheema fell thereafter, unable to bear the sorrow of seeing his brothers die.
Yudhisthira spoke while walking on: “Bheema was boastful about his strength and ate in excess. That was his failing” 

And now only Yudhisthira and the dog were left, continuing the journey together.
And finally, Indra descended in his chariot. He praised the extraordinary qualities of Yudhisthira and invited him into the chariot to ascend to heaven.
“The dog must come with me,” said Yudhisthira

“That is not possible,” said Indra. “All cannot attain heaven. The dog is old and thin and has no value.” “In that case, I do not seek heaven, “replied Yudhisthira. “The dog was my faithful companion and I cannot abandon it. It sought my help and gave me unconditional love. The pleasures of heaven will mean nothing to me in comparison to its grief. It has done nothing to deserve abandonment and had none of the weaknesses of my wife and brothers. If it does not deserve to go to heaven, then neither do I.”

And so he turned back. “Stop!” cried Indra. “None have the qualities that you possess, O Yudhisthira! The dog is Dharma, from whom you have descended!”
And indeed, the dog had transformed into the God of Dharma and blessed Yudhisthira for his complete lack of selfishness and dedication to righteousness in all circumstances. And thus rose Yudhisthira to heaven in the chariot of Indra.
