How to use full version: Simply fill the toy with biscuit treats by using the large hole. Place the toy on the ground for your dog to investigate. You may have to place one treat which is easy to knock out. It is important that you don’t remove the treats for them, because they will learn that you will dispense the treats for them and they will not then try to figure it out! Dogs can be lazy and clever. Additionally, you can apply a paste treat in between the bristles or inside the toy if your dog prefers paste treats — ideal if your dog has missing teeth.
