Monitoring body temperature and respiratory activity during exercise presents a significant challenge in canine research. Sled dogs, in particular, can experience dehydration and heat stress during prolonged endurance training. Understanding how these physiological parameters change during exercise can help researchers improve animal health, performance, and welfare.
Researchers at the University of Guelph investigated whether a diet enriched with soluble fiber could help trained sled dogs maintain better hydration during exercise. To answer this question, they needed a reliable way to continuously monitor body temperature and respiratory rate while the dogs were actively running.
Using emkaPACK jacketed telemetry, the research team successfully collected physiological data in real time without restricting the animals’ movement (Thornton E. et al., 2021).
Collecting reliable physiological data during intense exercise is difficult. Traditional monitoring systems often require restraint, wired connections, or laboratory conditions that can interfere with natural behavior.
For researchers studying exercise physiology, obtaining accurate measurements while animals move freely is essential. Sled dogs provide an excellent model because they perform sustained endurance exercise under demanding environmental conditions.
The challenge was clear:
The study revealed several interesting findings.
Despite differences in body temperature, respiratory rates were not significantly affected by the dietary intervention.
This finding suggests that body temperature may be a more sensitive indicator of subtle hydration-related changes than respiratory rate in these conditions.
Overall, the data of this pilot study are encouraging and indicate that a diet with increased soluble fibers may have beneficial effects in trained sled dogs.
Beyond the nutritional findings, this study demonstrates the value of wireless telemetry for physiological monitoring in freely moving animals.
The ability to continuously collect high-quality respiratory and temperature data during exercise opens opportunities for research in:
For investigators seeking reliable physiological measurements outside the laboratory, telemetry provides a practical and scientifically robust solution.
