Dogs need to encounter and overcome physical and mental challenges to remain happy and well. Unless this fundamental need is met, the dog will be inert and passive and may develop behavioural problems. It is therefore every dog-owner's duty to arrange appropriate stimulation for their dog. The reward is a happy and balanced companion who is permitted to express its specific behaviour and who has a close and harmonious relationship with humans. In this book, Anders Hallgren describes simple exercises designed to stimulate and improve your dog's senses. It is not vital that the dog learns to perform these tasks perfectly, but to challenge its mind and intelligence.
