Giant Breed Dog Exercise Requirements

Giant breed dogs are known to be docile, have huge loving hearts, and even bigger personalities. There is no official definition or guideline of what breeds are considered giant breed. A general guideline is any breed that is 100 lbs or more at full size. Some common examples of giant breed dogs are Great Dane, Leonberger, Newfoundland, St Bernard, Great Pyrenees Mountain dog and many of the mastiff breeds.

Giant breed dogs are actually less robust than smaller dogs and more fragile than they look. they are prone to some issues and limitations.

Joint Issues

It is advised to not run them on hard surfaces or do any activity that is high impact. Refer to “Exercising a puppy” for more information on this topic. Even as an adult it is still important to not do activities that put stress and strain on their bones and joints. The best exercise for the giant breed dogs is generally regular moderate exercise. This includes shorter distance walks, play with other dogs and a good game of fetch.

Breed Specific exercise recommendations.

It is difficult to give a definitive guide or outline on how to exercise a giant breed dog as the requirements vary from breed to breed and even between individual dogs of the same breed. Typically, a larger example of a certain breed tends to be less active than a smaller example of the same breed. We will look at some of the Giant Breed dogs and outline the activities and exercise that is best for them. In most cases, moderate low impact daily exercise with added mental stimulation will keep a giant breed dog happy and healthy. Social play with other dogs is a good idea, but just keep in mind that the Giant breed dog will tire quicker than the other smaller dogs.
The Giant breed dog is also very adept at pulling so you can include some cart pulling type exercise if you desire.

Great Dane

Daily walks are highly recommended with Great Danes and offer mental stimulation and socialization. A half hour to 1-hour walk should be planned at least once a day. Keep in mind that the pace a human walks will only allow a Great Dane to slowly lumber along requiring a longer walk and more time. Jogging with a Dane will actually allow it to gait at a natural aerobic pace. If they are showing signs of tiring that is probably sufficient for that day.
