What is meant by 'canine fitness' in the context of rehabilitation?

The concept of 'canine fitness' in the context of rehabilitation focuses on a dog's overall capability to engage in physical activities while minimizing fatigue and the risk of injury. This involves assessing the dog’s strength, endurance, flexibility, and balance as part of its rehabilitation regimen. A dog that is fit is able to perform various tasks and movements efficiently, indicating its readiness for activities after an injury or during recovery from a medical condition.

In contrast, the maximum weight a dog can lift is more relevant to strength training rather than overall fitness. The frequency of a dog's exercise pertains to how often a dog gets physical activity, which is important but does not fully encapsulate the idea of fitness. Similarly, the amount of food a dog consumes is more about dietary needs rather than fitness itself. Therefore, the first option accurately encapsulates the essence of canine fitness as it relates to rehabilitation, highlighting performance capability without undue fatigue.
