In spite of their great size, the very biggest dogs are usually quite reserved, and surprisingly do not require as much exercise as some of the large or medium sized breeds. However, they tend to be quite expensive to maintain and have the shortest life span of all the dog sizes.
If you are considering getting a giant dog breed you are going to need slightly more room to keep it. It is also important not to over-exercise giant breed puppies, otherwise their developing bones may become deformed.
