Dog Elixir is an item in Fable II that will heal your dog if he is wounded in combat. This item can be accessed from the Dog category on the Expression Wheel. The elixir is found in a chest by your caravan in the Gypsy Camp, the same chest in which Theresa left you some equipment at the beginning of the adolescence phase of the game. The dog elixir has infinite uses and each use will give your Hero a purity point.
