How often do you take your Mastiff walking? Our ten week old, we try to take him once or twice a day so that he gets his proper exercise, but he usually plants his feet down and refuses to go walking. He is really hard to get going, but he has no problem running around in the back yard playing. Exercise isn't an issue, just walking. My wife can usually make him walk, but the rest of us have a real hard time. This may be a walking issue, or it may be an attachment issue. Any thoughts or ideas? What do you do to make sure your Mastiff gets his daily exercise?
