Slayer

Slayer is one of the eight dogs you can adopt at the beginning of the day.

When you first see her at the yard, she is skittish and does not want to be approached or pet.

Slayer's Quest
As per her skittish nature when you meet her, Slayer's quest revolves around her over-coming her fears. In order to activate the path to complete her quest, when you first see an elk on your journey, you need to chose the option to try and go look at it. When you do this, Slayer will prevent you from doing so and you will continue on your journey without losing any hunger. This will prompt the "Slayer is afraid of elk" text to appear on your screen.

In order to move Slayer's quest forward, you must pet her at camp. You will then talk to her about overcoming her fears.

Next time you find an elk, you will want to pursue it again. Slayer will accompanied you and howl, and you can then chose to congratulate her for showing she wasn't afraid.
