One of the largest dogs in the world today is the Neapolitan Mastiff, an ancient dog breed descending from the Roman Molossus. This breed was originally cross-bred with other large dogs. Their offspring were used as watchdogs. Unfortunately, the Neapolitan Mastiff's earliest offspring were likely used to entertain people in the Colosseum, where the dogs fought each other and people. Today, the Neopolitan Mastiff is a companion and watchdog; the breed can also become lazy if not prompted to exercise regularly. Often, a daily walk around the neighborhood is sufficient exercise for the Neapolitan Mastiff; however, there are other activities with which you can engage your pup.
The Neapolitan Mastiff may be a giant, but, they are often gentle, loving giants. They need to be prompted to exercise daily. The Neapolitan Mastiff is prone to laziness and obesity if their owners do not insist upon exercise. Walking is the best exercise for the gentle giant. You can begin walking outdoors when the Neapolitan puppy has completed all immunizations. Start slowly and work up to at least one half hour of daily exercise.
