Exercise-induced gastrointestinal disease (EIGD) has been reported in all domestic athletes. In dogs and humans, EIGD is most commonly associated with ultra-endurance racing sled dogs and marathon/triathlon competitors, respectively, suggesting that the syndrome is specifically a function of prolonged exercise. However, EIGD is also common in horses that exercise for brief periods, and more recently, EIGD has been identified in Labrador retrievers that perform off-leash explosive detection patrols. In this study, we tested the hypothesis that EIGD could be induced in retrievers performing competition-style retrieves. Gastric endoscopy and histopathological examination of gastric biopsies were performed on 10 healthy retrievers before and 24 h after a series of multi-set retrieves totalling over 5 km. Although the exercise challenge resulted in a small but statistically significant increase in gastric endoscopy severity score, it did not result in a higher prevalence of clinically-significant gastric disease or changes in gastric histopathology. We conclude that competitive retrieving is unlikely to induce clinically-significant gastric disease in healthy dogs.

Abstract The total energy expenditure of a racing sled dog can exceed 500 kcal/kg bodyweight during typical events spanning a week or more. Based on early research, as well as practical considerations, modern commercial diets are formulated to meet these energy requirements using fat and protein. However, more recent research provides a clear picture of a canine athlete with glucocentric metabolism, including many conditioning-induced adaptations oriented towards sustaining submaximal exercise with glucose as the primary metabolic fuel despite the consumption of fat as the primary dietary energy source. The specific strategies used by racing sled dogs to maintain a robust supply of glucose during exercise, as well as the possible role of fat in facilitating that metabolic priority, is the subject of ongoing research.
