What is the main conflict in Daughter of the Mountains by Louise S. Rankin?

Daughter of the Mountains is a story about a little Tibetan girl named Momo who had always wanted a red-gold Lhasa Terrier like those owned by Tibetan Buddhist priests. The story begins with Momo's obsession to acquire a Lhasa Terrier for herself and then receiving one tied to a prophecy that the dog will bring adventure and fortune. When the dog, Pempa, is stolen by a trader, Momo pursues him all the way to India, by herself, until she finally tracks down the British woman to whom Pempa was sold. When the woman, Lady Paton, hears Momo's story and sees the bond she has with Pempa, Paton graciously returns Pempa to Momo and showers fortune on her family.
