Some dog breeds were developed to perform specific jobs. These dogs with a purpose usually need more physical stimulation. High-energy dogs will bore easy so new games and challenges should be used on walks and outings. All dogs need mental stimulation and can bore but working dogs, herding dogs, hunting dogs and sporting dogs may have more energy and need to burn more calories. Since these dogs are usually kept as pets now rather than working in their ‘field’ they will need to do things that will feed that natural desire to do what they were bred for. Some smaller dogs may only need a half hour walk a day and light play to keep them in shape and in a good mood. Most large dogs will need an hour or more of exercise or play a day. If the dog is a short-nosed breed it will not likely need a lot of exercise. ‘Exercise’ does not include time in the back yard- the dog does not consider that stimulating and will not likely exercise on its own. Dogs will get bored if only let out in the back yard or for short breaks. New places have new smells and smells are how your pooch discovers the world around him. Pet parents can consult their veterinarian to find out how much exercise the dog can handle. It may be unsuitable for some dogs with health issues to work out too much. Observe your dog to make sure it is not too tired or worn out. Always make time for breaks.
