1. What is MER for Dogs?

The Maintenance Energy Requirement (MER) is the number of calories a dog needs at rest to maintain its current weight. For weight loss, we multiply by a factor less than 1 to create a calorie deficit.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( W \) — Ideal body weight in kilograms
• \( factor \) — Adjustment multiplier for weight loss (0.6-0.8)

Explanation: The equation accounts for the metabolic rate scaling with body weight, with different factors for different weight loss goals.

3. Importance of Weight Management

Details: Proper calorie control helps dogs lose weight safely (1-2% body weight per week), reducing risk of diabetes, arthritis, and other obesity-related conditions.

4. Using the Calculator

Tips: Enter the dog's ideal weight (not current weight if overweight) and select an appropriate weight loss factor. More aggressive factors (0.6) should be used under veterinary supervision.

5. Frequently Asked Questions (FAQ)

Q1: How fast should my dog lose weight?
A: Healthy weight loss is 1-2% of body weight per week. Rapid weight loss can cause health problems.

Q2: What if my dog isn't losing weight?
A: Consult your vet - you may need to adjust the factor lower (but never below 0.6 without supervision).

Q3: Should I use current or ideal weight?
A: Use the ideal/target weight for the calculation to determine appropriate calorie intake.

Q4: Are there exceptions to this formula?
A: Yes - very small/large breeds, senior dogs, and dogs with medical conditions may need customized plans.

Q5: How often should I recalculate?
A: Re-evaluate every 2-4 weeks as weight changes, adjusting calories as needed.
