Define overload and progression in the context of MWD conditioning.

• A. Overload means staying within current capacity; progression means randomly varying load.
• B. Overload means reducing rest; progression means decreasing load.
• C. Overload means adding more gear; progression means skipping sessions.
• D. Overload means increasing training stress beyond current capacity; progression means gradually increasing volume, intensity, or complexity to elicit adaptation without injury.

Answer: (D)

In MWD conditioning, you push the dog's limits in a controlled way to provoke adaptation. Overload is increasing training stress beyond what the dog currently tolerates, such as longer runs, higher intensity, more tasks in one session, or greater distance, all aimed at challenging the system to improve. Progression is the careful, gradual ramp of those demands—raising volume, intensity, or task complexity in small steps so the dog keeps adapting without overreaching and risking injury.

For example, after the dog tolerates a 2-mile search well, overload would be adding a longer run or a tougher scent task in the same week. Progression would then be increasing distance or session difficulty again over subsequent weeks, but only gradually and with recovery built in. The other ideas—staying within current capacity, cutting rest, decreasing load, adding gear without a plan, or skipping sessions—don’t produce the ongoing stimulus and safe adaptation that overload and progression together are meant to achieve.
