This is the little Edward Thumb-Sucker with his dog Henry the guard. The dog makes sure, that nothing happens to the boy. Edward eats titbits and he likes it. The dog Henry is envious, he wants to have something as well. Edward turns away from the dog, he doesn’t want to share. Maybe he isn’t allowed to share with the dog, maybe the parents didn’t allow it.
Edward gets into trouble, because he has a hole in his trousers. Henry walks around the boy and empties the can. Hence Edward gets in trouble once more.
We have to give the boy the opportunity to achieve something. And when he is grownup, he will be a veterinary.
