As with all dogs regular exercise is essential for their good health, both physically and mentally, this is more so for Boxers. So if you are thinking of a Boxer, you need to be very active yourself. The working type breed require a lot of exercise and need to be able to run off the lead in open spaces to burn off some of their energy. Boxers have a massive energy reserve and will still have energy left even after working all day. If they don’t get enough exercise they will become bored and with boredom comes naughtiness and behaviour issues. And, they do love a game of retrieve, and will chase a ball thrown for them all day.
