Active range of motion, or aROM, is the movement a dog produces voluntarily using their own muscles. During a canine fitness exercise, aROM can help us observe how much movement the dog can access and control in that particular position or task.
Passive range of motion, or pROM, is the range available when an external force (usually a person) moves a joint or body region without the dog actively producing the movement. When assessed appropriately, pROM can provide information about the range available passively, but it does not show whether the dog can actively access or control that range.
This distinction matters because a dog may have passive range available, but that does not necessarily mean they have the strength, coordination, stability, comfort, or task understanding needed to use that range actively.
In canine fitness, the goal is not to create as much flexibility as possible. The goal is useful, comfortable, controlled movement through ranges appropriate for the individual dog.
