What are the primary energy systems utilized in canine endurance activities, and how do they influence program design?

• A. Phosphagen and glycolytic; design focuses on maximal lifts only.
• B. Aerobic and anaerobic energy systems; longer aerobic sessions for base, intervals or sprint work for anaerobic bursts.
• C. Only aerobic; no intervals.
• D. Only anaerobic; high intensity all the time.

Answer: (C)

Endurance conditioning hinges on using both aerobic and anaerobic energy systems. For sustained canine work, building a strong aerobic base is essential—the dog learns to use oxygen efficiently, develops better mitochondrial density and capillarization, and can sustain effort over longer periods. But endurance events also require occasional higher-intensity efforts, which tap into anaerobic pathways to produce quick energy and improve the dog’s ability to accelerate, hold a faster pace, and recover between bursts.

A well-designed program blends longer, steady aerobic sessions to develop the base with targeted intervals or short sprints to stress the anaerobic system, enhance lactate tolerance, and improve pacing and recovery. This combination ensures the dog can maintain effort over time while still delivering and sustaining faster efforts when needed.

Choosing an approach that uses only aerobic activity neglects the benefits of anaerobic work, and an approach that emphasizes only high-intensity work can lead to overtraining and insufficient aerobic development. Conversely, focusing exclusively on maximal lifts is not aligned with endurance programming, which aims to improve sustained performance and efficient energy use over time.
