1. What is a MER Calculator for Dogs?

Definition: This calculator estimates the Maintenance Energy Requirement (MER) for dogs to lose weight based on their ideal weight and a reduction factor.

Purpose: It helps pet owners and veterinarians determine appropriate calorie intake for overweight dogs to achieve healthy weight loss.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( MER \) — Maintenance Energy Requirement (kcal/day)
• \( W \) — Ideal body weight (kg)
• \( factor \) — Reduction factor (typically 0.8 for weight loss)

Explanation: The formula calculates the dog's metabolic rate based on body weight, then applies a reduction factor for weight loss.

3. Importance of Proper Calorie Calculation

Details: Accurate MER calculation ensures safe, gradual weight loss (1-2% of body weight per week) while maintaining proper nutrition.

4. Using the Calculator

Tips: Enter the dog's ideal weight in kg and a factor (default 0.8). The factor should be less than 1 for weight loss.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical factor for weight loss?
A: For weight loss, factors typically range from 0.7 to 0.9, with 0.8 being most common.

Q2: How do I determine my dog's ideal weight?
A: Consult your veterinarian who can assess body condition score and recommend an appropriate target weight.

Q3: When would I use a factor of 1?
A: A factor of 1 is used for maintenance calories when the dog is already at ideal weight.

Q4: How often should I recalculate MER?
A: Recalculate every 2-4 weeks as your dog loses weight, or as directed by your veterinarian.

Q5: Is this calculator suitable for puppies?
A: No, this calculator is for adult dogs only. Puppies have different nutritional requirements.
