Finding and unlocking every pet in Assassin’s Creed Shadows in a noble goal, but you will need to traverse a large part of the map to do it. There are a lot of options, and even more than it appears at first glance. Once you unlock a pet, you can place it in your Hideout so that you can pet it whenever you want. It’s a great perk and one of the great things you can do that is different in this game than in past ones.
