Why did koskoosh give up the fight with wolves?

It seems you're referencing the short story "The Call of the Wild" by Jack London. While Koskoosh is a character in the story, he doesn't fight wolves. He's an old, blind, and aging dog who is abandoned by his pack.

Here's why Koskoosh gave up:

* He is old and weak: Koskoosh is a senior dog, no longer capable of fighting off a pack of wolves. He is blind and unable to see the threat approaching.

* He is alone and abandoned: His pack has moved on, leaving him to face the wolves alone. He has no hope of rescue.

* He accepts his fate: Koskoosh understands his situation and knows he cannot win. He chooses to accept his fate and die with dignity.

The story focuses on Koskoosh's final moments, showcasing his acceptance of death and the power of the wild's natural order. It's not about a fight against wolves, but rather a reflection on the cycle of life and death.
