Read this excerpt from White Fang by Jack London.

White Fang saw his mother taken aboard Three Eagles’ canoe, and tried to follow her. A blow from Three Eagles knocked him backward to the land. The canoe shoved off. He sprang into the water and swam after it, deaf to the sharp cries of Grey Beaver to return.

This is an example of conflict between

Grey Beaver and Three Eagles.
White Fang and nature.
White Fang and Three Eagles.
White Fang and Lip-lip.
