Dog is dissatisfied with the way he is treated; so he goes to Medicine-Man for help, and asks for a medicine so powerful that, if he looks at the person who strikes him, that person will fall dead. Medicine-Man agrees to give him the medicine, but adds, that, if he puts his mouth on what does not belong to him, the medicine will lose it power.
The first time Dog tests the medicine, it fails. He is caught eating the chop of his master's children, and he is beaten. As he run away, he keeps looking back, expecting in vain to see his master drop dead. Dog goes to Medicine-Man to complain that the medicine is worthless.
"Tell me, why were you being beaten?" asks Medicine Man.
"Really for nothing at all; only because I was eating some chop of my master's children," answers Dog carelessly.
"So you eating other people's chop nothing?" asks Medicine-Man.
"Well you have ruined the medicine, and I can do nothing more. You
may therefore expect to be flogged to the end of time."
To this day Dog looks back, as he runs away, at the person who has beaten him, vainly hoping that the medicine will work.
