Exercise (walking) is the most important part of a dog's health. In the wild, dogs roam for miles every day and that natural instinct to roam is still present in all dogs - even yours. All dogs have different levels of energy - but even dogs with the lowest amount of energy need at least one period of continuous exercise a day, most experts agree. A tired dog is a well-behaved dog. Through regular walking, many behavioural issues can begin to be resolved. After a long walk, your dog is in a calm state of mind and is more receptive to training and behaviour corrections. Many dog owners feel that their back garden or an outside place for their dogs to play is enough. It's not. To your dog, your garden is nothing more than a large kennel. They must be able to travel over a distance at a continuous pace every day to get proper exercise.
