Playing with the dog is not only fun, it strengthens your bond with your pet, decreases problematic behaviour and ensures that the dog stays fit, both physically and mentally.
While playing there are some issues that require attention. Not every game is suitable for any dog or dog-owner combination. However, a suitable game may be found for every dog. Of course, the game and the toys must be safe and rules must apply, for both dog and owner.
