1. What is the MER Equation?

The Maintenance Energy Requirement (MER) equation estimates the daily calorie needs for dogs based on their weight and activity level. It helps determine 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
• \( factor \) — Activity level multiplier (see below)

Common Activity Factors:

• 1.0 - Neutered adult (normal activity)
• 1.6 - Intact adult
• 1.8 - Light work
• 2.0 - Moderate work
• 3.0 - Heavy work or pregnancy (last trimester)
• 4.0 - Lactation (peak)
• 2.0 - Growth (weaning to 4 months)
• 1.6 - Growth (4 months to adult size)

3. Importance of Calorie Calculation

Details: Proper calorie intake is essential for maintaining optimal weight, preventing obesity or malnutrition, and supporting specific life stages or activity levels.

4. Using the Calculator

Tips: Weigh your dog accurately. Select the appropriate activity factor based on your dog's life stage and activity level. Monitor weight and adjust as needed.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate but individual needs may vary by ±20%. Monitor your dog's weight and adjust as needed.

Q2: What if my dog is overweight?
A: For weight loss, feed 80% of the MER for ideal weight, not current weight. Consult your vet for a weight loss plan.

Q3: How often should I recalculate?
A: Recalculate after significant weight changes, activity level changes, or life stage transitions (e.g., puppy to adult).

Q4: Does this work for all dog breeds?
A: The equation works for most breeds, but giant or toy breeds may have different metabolic rates. Consult your vet.

Q5: What about senior dogs?
A: Senior dogs may need fewer calories (factor ~0.8-1.0) unless they remain very active. Monitor body condition.
