Additionally, outdoor dogs tend to bark so much that no one pays attention to them after awhile, even if the reason is legitimate. Many people feel that leaving their dog in the yard allows the dog to get exercise. This is not as true as it seems. This is caused by a fence that, as stated before, allows the dog to perceive stimuli without the opportunity to interact with it. This activity does not have the healthful benefits of exercise.
Exercise comes from taking the dog for walks and playing with the dog.
Health and behavior Outdoor dogs, almost without exception, are less healthy, and therefore more expensive, than indoor dogs. They are exposed more to diseases and accidents. Outdoor dogs, even for dogs that spend only half a day outdoors, are learning the rules of the yard. These rules are that it is okay to bark at any time, to eliminate any time and anywhere, and to dig. None of these behaviors are compatible with living indoors.
