If the dog is training, working and for long periods of time, then just feeding a high protein and fat diet isn't sufficient. Even with a premium dog food.
It'a all part of a conditioning program, take for instance that if you trained a dog 2 hours a day in agility(not recommend or done) but with all that training the dog still wouldn't be fit enough to be in top condition for agility.
Too many dogs are not fed nor conditioned properly for the job we expect them to do which results in more injuries from fatigue and little stamina.
