Ocular and Superficial Body Thermographic Findings in Sled Dogs before and after Competition

SIMPLE SUMMARY: Thermography may provide useful data during competitions with sled dogs for rapid clinical screening during activity. The results of this study showed a significant increase in post-competition ocular temperature of both eyes, regardless of the length of the race. Superficial body temperatures also increased after competition, but it was particularly affected by environmental and subjective factors. ABSTRACT: Competitions involving sled dogs are rapidly growing and body temperature assessment could represent a prompt and non-invasive method of screening for potential pathological conditions during or after activity. The aim of this clinical study was to evaluate if thermography is able to monitor the pre- and post-competition ocular and superficial body temperature variations during a sled dog competition. It subsequently compared the data relating to the ocular temperatures in different race types: mid-distance (30 km) and sprint (≤16 km). Results showed a statistically significant increase in post-competition ocular temperature of both eyes, regardless of the length of the race. The relative increase in the temperatures of the other body surfaces was lower than the expected values, probably due to the influence of environmental and subjective factors such as the type of coat of the Siberian Husky or subcutaneous fat. Infrared thermography has therefore proved to be useful method in sled dog competition conditions for screening superficial temperature variations, as the investigation is normally conducted in an external environment and often in demanding work conditions.
