We often think of exercise only as a health issue, but it has significant day-to-day effects on a dogâs behavior as well. Dogs â particularly puppies and young dogs â have a lot of energy, and if they donât get the chance to burn it off, destructive behavior is often the result. Dog parks are popular places for off-leash exercise and romping with other dogs, which is exactly what most dogs need. 2  However, not all dogs can play nicely with others. 3  If your dog doesnât like other dogs, the dog park is definitely not the place for him. 4  Doggie day care can exercise both his mind and body.
When running with your dog, some of the signs you need to look out for showing they may have over done it are: 1  Starting to fall behind, and slowing down compared to their usual performance. 2  Limping or lameness in any way and to any level of severity. 3  Shortness of breath or excessively panting during the exercise.
