Calculation Components
  • Dog's body weight in kg or pounds
  • Activity level multiplier (1.2-3.0)
  • Life stage considerations
  • 10% maximum Daily calories from treats

Method
 

Calorie Calculation Process
  1. Calculate your dog's Resting Energy Requirement (RER) using the formula: RER = 70 × (body weight in kg)^0.75. For dogs weighing 2-45 pounds, use: RER = (body weight in pounds ÷ 2.2) × 30 + 70.
  2. Apply the appropriate activity multiplier: Sedentary dogs (RER × 1.2-1.4), typical adult dogs (RER × 1.6-1.8), active dogs (RER × 2.0-2.5), working dogs (RER × 3.0+), puppies (RER × 2.0-3.0).
  3. Monitor your dog's body condition weekly using the 9-point body condition scoring system. Check that ribs are easily felt with gentle pressure and waist is visible from above.
  4. Account for treats and extras, ensuring they don't exceed 10% of daily calories. Reduce meal portions if using high-calorie treats during training.
  5. Make adjustments in 10-15% increments if needed, waiting 2-3 weeks between changes to see results.
  6. Consider life stage adjustments: pregnant dogs need 1.5-2x normal calories in last trimester, nursing mothers need 2-4x normal intake, senior dogs often need fewer calories.

Notes

Never reduce calories by more than 25% without veterinary supervision. Reassess calorie needs every 3-6 months for adult dogs, monthly for puppies. Treats should comprise no more than 10% of daily calories. Always transition food changes gradually over 7-10 days. Use kitchen scales for accurate measuring rather than measuring cups. Monitor body condition weekly using the 9-point scoring system.
