How do you identify cognitive fatigue during scent work conditioning?

• A. Deterioration in task accuracy, slower responses, reduced enthusiasm, and repeated mistakes despite breaks
• B. Increased eagerness and faster responses
• C. No change in performance despite fatigue
• D. Improved scent discrimination accuracy

Answer: (A)

Cognitive fatigue shows up as a decline in mental task performance. In scent work conditioning, the dog must maintain attention to odor cues, make quick, accurate identifications, and stay motivated across sessions. When fatigue affects cognition, accuracy drops, processing slows, engagement wanes, and errors repeat even after breaks. This pattern indicates the dog is struggling to sustain the mental effort needed for scent discrimination, not just tiring physically. The signs of increased eagerness and faster responses would point to arousal rather than fatigue, and no change or improvement would not fit the fatigue pattern. So the combination of deteriorating accuracy, slower responses, reduced enthusiasm, and repeated mistakes despite breaks best reflects cognitive fatigue.
