Study Reveals the Most Effective Cooling Method for Hyperthermia in Dogs

Study Design
This randomized, crossover study assessed four distinct cooling protocols after exercise: (1) neck chemical ice packs, (2) wet (22 °C) neck towels, (3) wet (22 °C) axillae towels, and (4) voluntary head immersion (“dunking”) in 22 °C water. Following the cooling interventions, dogs were monitored during a 40-minute rest period to evaluate the effectiveness of each method in reducing core body temperature.
Findings
The findings were significant. The voluntary head dunking method, which included controlled water ingestion, resulted in the lowest mean core temperature within the first 5 minutes post-exercise. This method was the only cooling protocol that prevented an initial post-exercise temperature rise. All methods ultimately enabled the dogs to return to baseline temperatures, but the dunking protocol excelled in providing rapid cooling.
The study concluded that trained voluntary head dunking with limited water ingestion is the most effective cooling method for dogs experiencing exercise-induced hyperthermia in field situations. This technique is particularly beneficial for dogs with normal mental status, allowing them to pause panting and effectively cool down.
Clinical Relevance
The principle of “Cool first, transport second” is crucial in mitigating the morbidity and mortality associated with acute heat injuries. The trained voluntary head dunk serves as a practical solution when whole-body immersion is not feasible. It effectively prevents post-exercise temperature rises and rapidly reduces core body temperature within the first critical minutes.
