Buying Guide
Calorie Needs for Active Medium Breeds
A highly active 35-lb dog may need 1,400-2,000+ kcal/day. Performance formulas with 450-550 kcal/cup allow adequate nutrition without feeding enormous volumes.
Fat as Primary Energy for Endurance
For dogs involved in sustained activities, fat is the preferred fuel source. Performance formulas should have 20-28% fat content. Fat provides 9 kcal/g vs. 4 kcal/g for protein and carbohydrates.
Post-Exercise Protein for Muscle Recovery
After intense activity, dogs need protein for muscle repair. Feeding within 30 minutes of exercise with a protein-rich food enhances recovery. Look for 28-35% protein content.
Hydration and Electrolytes
Active dogs lose significant water through panting. During intense exercise days, add extra water to food or provide electrolyte-enhanced water. Watch for signs of dehydration.
Frequently Asked Questions
How much more food does an active Border Collie need?
A working Border Collie can need 50-100% more food than a sedentary dog of the same weight. A 40-lb active Border Collie doing 4-6 hours of herding work may need 1,600-2,000 kcal/day.
Should I feed my active medium dog before or after exercise?
Avoid large meals within 2 hours before vigorous exercise to reduce bloat risk. Feed the main meal after exercise and recovery. High-activity dogs may benefit from 3-4 smaller meals throughout the day.
Do active medium breed dogs need supplements?
Active dogs may benefit from fish oil (for inflammation and joint recovery), glucosamine/chondroitin (for high-impact activities), and electrolyte supplementation during extended exercise.
When should I switch an active dog to a maintenance diet?
When your dog’s activity level decreases due to age, injury, or lifestyle change, transition to maintenance or senior food to prevent obesity from a still-high-calorie performance diet.
