This page offers a guide on where to locate and how to complete A Dog’s Rescue, which is a Mystery located in Oxenefordscire, Assassin’s Creed Valhalla.
Save the Pet
This Mystery is located between Buckingham and Linforda. When you approach the mystery, you’ll notice that the house nearby is ablaze. Speak to the woman outside and she’ll ask you to save her dog, who’s still in the house. Head around the right side of the house and shoot through the smaller wooden wall to enter into the house.
The pet you’re looking for can be found behind another breakable wall. For the both of you to escape the house you’ll need to move the large moveable shelf. You can only move it aside by breaking the vase to the left. Finallu, you’ll then need to break through the wooden wall behind the moveable object to escape. Speak to the woman again and with her dying breath, she will ask you to look after her “dog” (who you have discovered is actually a fox). When you leave the area, you’ll notice the fox following you, after a short while, Eivor will tell the fox that it can live at Ravensthorpe, and it will become a new settlement pet.
