Optimizing your four-legged athlete’s diet is key to enhancing performance, but also to preventing various sports-related issues such as musculoskeletal, joint, or metabolic disorders.
To assess the nutritional needs of a sporting animal—both quantitatively and qualitatively—we consider:
- Body composition: the formula used to determine energy needs includes metabolic weight.
- Metabolism: every individual has a unique metabolism. Sled dogs, particularly the Siberian Husky, have a more efficient metabolic rate (they make better use of the energy they consume) and superior thermal insulation (resulting in lower energy expenditure for thermoregulation).
- Activity level: the energy pathways used during exercise depend on the duration and intensity of the activity, so this must be considered when calculating their diet.
- Stress levels (physical and/or psychological): high-intensity physical activity is a stressor for the body, making it essential to mitigate its effects—largely through nutrition. Psychological stress, though not always present, is hard to eliminate entirely, especially during competitions (crowds, noise, travel, changes in routine, etc.). These factors alter the body’s energy requirements as well as its needs for minerals, vitamins, fatty acids, and more.
- Environment: for example, low temperatures increase energy needs.
Adjust Quantities
Quantitative changes are always challenging to assess in sporting dogs. The goal is to maintain their optimal weight by weighing them and checking their body condition score weekly, then adjusting the amounts fed accordingly. One hour of work roughly equates to a 10% increase in baseline energy needs. Daily exercise duration and intensity must therefore be factored in—these requirements can shift over time. During competition periods, for instance, needs may rise. Weather conditions should also be considered. Take sled dogs, for example: a day of racing in an Iditarod-style event (covering 200 km at -35°C) demands an energy intake of 11,000 kcal—about 10 times a dog’s maintenance needs!
Ensuring Quality
It is essential to prioritize an easily digested and metabolized energy source to maximize feed efficiency. Therefore, it is advisable to offer concentrated and highly digestible feeds, ensuring rapid and efficient energy utilization by muscle cells, minimizing intake volume and waste production, and reducing the risk of altered transit and fecal consistency.
It’s important to remember that fats are the primary energy source for sporting dogs. The balance between proteins, fats, carbohydrates, and more is particularly influenced by the type of physical activity: endurance dogs require higher fat intake than sprinters.
Fighting Stress
High-level sports and competition undeniably generate stress—both physical and psychological—of varying intensity. Travel, psychological environment, potential spectators, temperature, noise, and high-dose physical activity are all factors that contribute to increased production of "reactive oxygen species" in the body. It is therefore essential to be particularly vigilant in combating oxidative stress when planning nutrition, by including various sources of vitamins C and E, or superoxide dismutase, a powerful antioxidant.
Preventing Dehydration
While it may seem obvious, it’s important to remember that dehydration is a major concern in sports. It disrupts ionic balance (which needs to be restored by ensuring adequate intake of sodium, potassium, magnesium, etc.) and the acid-base balance, already compromised by potential acidification linked to the metabolic pathways involved (which vary depending on the type of sport).
Embracing Your Efforts
Adjusting energy intake to match training progression is key to optimizing performance. Planning your sporting dog’s feeding schedule in advance is therefore essential, taking into account rest periods, training phases, competition, and the detraining phase (gradual return to maintenance diet).
Support Recovery and Reduce the Risk of Disease Onset
Certain amino acids have notable effects on the body’s adaptability and recovery, particularly L-carnitine. Probiotics help improve digestive health and feed digestibility, leading to better nutrient absorption. Finally, physical activity always puts stress on joints and surrounding structures, so it’s important to prevent damage—especially by adding chondroitin sulfate, glycosaminoglycans, or essential fatty acids (omega-3) to the diet, as these support cartilage protection and help fight inflammation.
