This sheep dog is covered in his own blood after fighting off wolves protecting his flock, while the sheep gently comforts him.
Regardless of how physically strong or emotionally tough someone is, showing them how much you appreciate their efforts goes a long way.
The dog is willing to die for his sheep, and the gesture of the sheep comforting him is all he needs.
Never take someone for granted who is willing to fight for you or stand by you in your time of need. Appreciate their efforts, and show them that you are grateful.
