how the dog made the jackal howl: an angolan folktale

From  a collection of folktales of Angola, in literal translation:  here's why the jackal howls. His relative the Dog left him for tasty people food!

DOG AND JACKAL.
Jackal used to be in the bush with his kinsman, Dog. Jackal then sends Dog, saying: "Go to the houses, to fetch some fire. When thou comest with it, we will burn the prairie of grass; so as to catch locusts and eat." Dog agreed.
He started; arrived in the village. He enters a house; finds a woman, who is feeding her child (with) mush. Dog sat down; fire, he will not take it. The woman has fed her child; she scrapes the pot. She takes mush; she gives it to Dog. Dog eats; thinks, saying: "Why, I am all the time just dying with hunger in the bush; in the village there is good eating." The Dog settled (there).
Jackal, behind where he stayed, looked for the other, who was sent for fire; he does not appear.
The Jackal, whenever he is howling, people say, "The Jackal is howling, tway!" But no; he is speaking, saying: "I am surprised, I, Jackal of Ngonga; Dog, whom I sent for fire, when he found mush, he was seduced; he stayed for good."
