1. What is RER and MER?

RER (Resting Energy Requirement) is the number of calories a dog needs at complete rest, while MER (Maintenance Energy Requirement) accounts for normal activity levels. These values help determine appropriate food portions for optimal health.

2. How Does the Calculator Work?

The calculator uses these equations:

Where:

• \( weight_{kg} \) — Dog's weight in kilograms
• \( factor \) — Multiplier based on life stage and activity level

Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate, with adjustments for different activity levels and life stages.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation is crucial for maintaining healthy weight, preventing obesity, and ensuring proper nutrition for dogs at different life stages and activity levels.

4. Using the Calculator

Tips: Enter your dog's weight in kilograms and select the appropriate activity factor based on your dog's life stage and activity level.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert my dog's weight from pounds to kilograms?
A: Divide the weight in pounds by 2.205 to get kilograms (e.g., 20 lbs ÷ 2.205 = 9.07 kg).

Q2: What if my dog is overweight?
A: For weight loss, feed 80-90% of the RER value and consult with your veterinarian for a tailored plan.

Q3: How often should I recalculate my dog's calorie needs?
A: Recalculate whenever your dog's weight changes significantly or their activity level changes substantially.

Q4: Are there exceptions to these calculations?
A: Yes, very small or very large breeds, sick dogs, or dogs with special conditions may need adjusted calculations.

Q5: How do I apply this to my dog's food?
A: Check your dog food's calorie content (kcal/cup or kcal/kg) and divide the MER by this number to determine daily portions.
