When a snake touches the excrement of a goose, it will fester if it is not careful, until the whole body of the snake rots. Even if snakes want to be treated, there is nothing to improve. Even if the goose smells something, it will run away directly. And the goose's neck is so long that the snake can't bite it at all, but the goose is different. It can attack snakes directly with its mouth, especially Dagong Goose, and its scratching ability is stronger.
