A tired dog is a well behaved dog! Agility is a sport for handler and dog that challenges your mind and body (i.e. good for both of you). It is a great workout for both handler and dog. A few minutes of challenging your dogs mind can be more exercise than walking a few miles. Agility is one of the fastest growing dog sports and whether you want to compete of just play for fun it is a great way to bond with your dog and build the kind of relationship with your dog to be envied.
