DER Formula:
| From: | To: |
The Daily Energy Requirement (DER) formula calculates the estimated calorie needs for dogs based on their body weight and activity level. This helps ensure proper nutrition and weight management for canine health.
The calculator uses the DER equation:
Where:
Explanation: The equation accounts for the metabolic rate scaling with body weight, with different factors for different activity levels and physiological states.
Details: Accurate calorie calculation is crucial for maintaining optimal body condition, preventing obesity, supporting growth in puppies, and meeting energy demands during pregnancy and lactation.
Tips: Enter body weight in kilograms, select the appropriate factor based on your dog's activity level and life stage. All values must be valid (weight > 0).
Q1: What factors should I use for my dog?
A: Use 1.6 for typical adult dogs, 1.8 for active adults, 2.0 for working dogs, 3.0 for pregnant/lactating females, and 2.5 for growing puppies.
Q2: How often should I recalculate my dog's calorie needs?
A: Recalculate whenever your dog's weight changes significantly, activity level changes, or during different life stages (pregnancy, growth, senior years).
Q3: What if my dog is overweight or underweight?
A: Adjust the calculated value by 10-20% based on whether you need weight loss or weight gain, and consult with your veterinarian for specific recommendations.
Q4: Are there breed-specific considerations?
A: While the formula works for most breeds, giant breeds and toy breeds may have slightly different metabolic rates. Consult your vet for breed-specific advice.
Q5: Should I adjust for age?
A: Yes, senior dogs typically have lower energy requirements. Consider reducing the factor by 10-20% for dogs over 7 years old, depending on their activity level.
