Whether with the dumbbell, feed dummy or with a feed ball – retrieving things is a demanding task for dogs. Your dog must not damage the object in question and it is very important that your dog leaves it to you. It must therefore not defend it as his own prey. The human-dog relationship has long been anchored in retrieval: hunting dogs, for example, bring back game that has been shoot, ship dogs bring back nets. Teaching your dog, that he should bring you an object back, is not so difficult if you offer it a fair exchange in the form of treats. All you need is a feed dummy and of course a lot of patience.
