1. What is the MER Equation?

The Maintenance Energy Requirement (MER) equation estimates the daily caloric needs for dogs based on their weight and activity level. It provides a baseline for determining appropriate food portions to maintain healthy weight.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( weight_{kg} \) — Dog's weight in kilograms
• \( activity\_factor \) — Multiplier based on activity level (1.2-2.0)

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

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining optimal weight, preventing obesity or malnutrition, and ensuring proper nutrition for dogs.

4. Using the Calculator

Tips: Enter dog's weight in kilograms and select appropriate activity level. Weight must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my dog's activity level?
A: Sedentary = mostly indoor; Light = short walks; Moderate = regular exercise; High = active lifestyle; Working = service or hunting dogs.

Q2: What if my dog needs to gain or lose weight?
A: Adjust calories by 10-20% below MER for weight loss or above MER for weight gain, under veterinary supervision.

Q3: Does this apply to all dog breeds?
A: While generally applicable, some breeds may have different metabolic rates. Consult your vet for breed-specific advice.

Q4: How often should I recalculate MER?
A: Recalculate whenever your dog's weight changes significantly or activity level changes substantially.

Q5: What about puppies or senior dogs?
A: Puppies need more calories (2-3x MER), while seniors may need fewer. Always consult your veterinarian for age-specific recommendations.
