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's used to determine appropriate food portions and maintain optimal body condition.

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)

Activity Factors:

• 1.8 — Puppy (0-4 months)
• 1.6 — Puppy (4-12 months)
• 1.4 — Active adult
• 1.2 — Neutered adult
• 1.0 — Sedentary/obese prone
• 2.0 — Working/athletic dog

3. Importance of MER Calculation

Details: Accurate MER estimation helps prevent obesity or underfeeding, ensures proper nutrition, and supports overall health and energy levels in dogs.

4. Using the Calculator

Tips: Weigh your dog accurately in kilograms. Select the appropriate activity factor based on your dog's life stage and lifestyle. Monitor your dog's body condition and adjust as needed.

5. Frequently Asked Questions (FAQ)

Q1: How often should I recalculate my dog's MER?
A: Recalculate whenever your dog's weight changes significantly or their activity level changes (e.g., becomes more sedentary or starts training).

Q2: What if my dog needs to gain or lose weight?
A: For weight loss, feed 80-90% of MER. For weight gain, feed 110-120% of MER. Consult your vet for specific recommendations.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual needs may vary by ±20% based on metabolism, environment, and health status.

Q4: Should I use this for very small or very large dogs?
A: The equation works for most breeds, but giant breeds may need slightly less and toy breeds slightly more per kg of body weight.

Q5: How should I divide the daily calories?
A: Typically divided into 2 meals per day for adults. Puppies may need 3-4 smaller meals.
