I need your help figuring out the title of this

[Michele]

children's book. This is an older story about a dragon that two kids raise. They feed it food that they make called jumbles and as the dragon grows, they send it to the top of a mountain and it's tail wraps around the mountain. Sound familiar to anyone?

Does this sound familiar?
Le Guin, Ursula. Fire and Stone. Illus. Laura Marshall. New York: Atheneum, 1989. A relatively simple story of two children who help save their village from a dragon by feeding it rocks until it becomes a stone hill. As the dragon blends in with the landscape, and the children sing a sunrise song of birth and nourishment, we are reminded that in many times and places dragons have been seen in the sun, in the shapes of the hills, and in lightning. Unlike many other modern stories of children taming dragons, this one invites us to respect the dragon powers of the heavens and Mother Earth, which nurture us as well as terrifying us at times.

Hamm, I am not sure. This would have been much older than 1989. Think at least 1970, maybe later. I will look into the one you posted.
