Calculate your dog's daily calorie needs based on weight, age, activity level, and body condition
Every dog has unique calorie requirements based on their size, age, activity level, and metabolism. The Resting Energy Requirement (RER) represents the calories needed for basic body functions, while the Daily Energy Requirement (DER) accounts for activity, growth, and other factors. Proper calorie intake is essential for maintaining a healthy weight and preventing obesity-related health issues.
| Life Stage | Energy Multiplier | Feeding Frequency | Special Considerations |
|---|---|---|---|
| Puppy (0-12 months) | 2.0 × RER | 3-4 meals/day | Rapid growth requires more calories |
| Adult (1-7 years) | 1.4-1.6 × RER | 2 meals/day | Varies by activity level |
| Senior (7+ years) | 0.8-1.2 × RER | 2 meals/day | Lower metabolism, less active |
| Pregnant (late term) | 1.5-2.0 × RER | 3-4 meals/day | Increased needs for fetal development |
| Lactating | 2.0-4.0 × RER | Free feeding | Depends on litter size |
Weight: 70 lbs (31.8 kg)
RER = 70 × (31.8^0.75) = 1,176 kcal/day
DER = 1,176 × 1.4 (moderate activity) = 1,646 kcal/day
Daily food: 1,646 ÷ 350 = 4.7 cups/day
Per meal: 4.7 ÷ 2 = 2.4 cups/meal
Weight: 5 lbs (2.3 kg)
RER = 70 × (2.3^0.75) = 130 kcal/day
DER = 130 × 0.8 (senior) × 1.2 (low activity) = 125 kcal/day
Daily food: 125 ÷ 350 = 0.4 cups/day
Per meal: 0.4 ÷ 2 = 0.2 cups/meal
Weight: 40 lbs (18.1 kg)
RER = 70 × (18.1^0.75) = 788 kcal/day
DER = 788 × 2.0 (puppy growth) = 1,576 kcal/day
Daily food: 1,576 ÷ 350 = 4.5 cups/day
Per meal: 4.5 ÷ 3 = 1.5 cups/meal (3 meals for puppies)
