Dog Sports Nutrition: Welfare Evidence for Working and Competing Dogs

Working and sporting dogs have nutritional requirements distinct from pet dogs, and evidence-based feeding practices significantly affect performance welfare and long-term health.

Key Facts

Sled dogs in endurance events require up to 10,000 kcal per day — approximately 10x a resting pet dog
High-fat diets (greater than 30% fat on dry matter basis) improve performance and reduce gastrointestinal distress in endurance dogs
Dehydration as little as 2% body weight impairs performance and is a welfare risk in all working dogs
Post-exercise muscle glycogen replenishment peaks within 30 minutes — immediate post-work feeding improves recovery
Calcium supplementation in growing sporting dogs is a welfare risk — excess calcium causes skeletal abnormalities

Welfare Considerations

Working dog nutrition is a welfare issue when inadequate fuelling leads to fatigue-related injury, dehydration, or metabolic compromise. The sports nutrition evidence base for dogs is growing rapidly, with clear evidence that diet composition, timing, and hydration management directly affect welfare outcomes. Breed and discipline-specific guidelines are available from veterinary sports medicine specialists — generic pet food recommendations are insufficient for dogs in high-intensity work.

What You Can Do

Consult a veterinary nutritionist if your dog participates in endurance, protection, or high-intensity sport
Ensure working dogs have access to water throughout activity and are weighed before and after to detect dehydration
Do not supplement calcium in growing dogs without veterinary guidance — it causes more harm than benefit
