Igloo

Igloo "Iggy" is one of the eight adoptable dogs at the beginning of the game.

When you first walk up to Iggy's house, she is buried under a pile of snow. She wags her tail excitedly at you, though, and if you chose to adopt her, your character mentions that Iggy's old owners say Iggy still loves the wild and wants to explore, but they were simply unable to provide her with that anymore.

Iggy's Quest
Iggy is a protective dog. Her quest is triggered by a rogue Muskox charging your sled. You can raise your gun to shoot but the Muskox tries to charge, prompting Iggy to jump into between you and the Muskox, injuring herself in the process.

Iggy's Abilities
Iggy will protect you from wolverines and musk ox.
