When a person or animal is tired, the muscles become weak and there is greater stress on the joint capsule and ligaments supporting the joints. When the animal is exhausted, there is decreased shock absorption and injury is more likely. Puppies naturally play and rest intermittently, thus longer periods of exercise should be approached gradually. An hour-long walk may not necessarily be harmful as long as it is not an hour the first time out. An hour jog may not be such a good idea because of the increased stress on the joints.
Nutrition is also an important factor in the development of orthopedic disease.
There is growing evidence that dogs who grow too quickly are more likely to develop hip dysplasia. Therefore, puppies should not be fed free choice and should be fed a diet appropriate to their age, breed and size.
