1. What is MER and RER?

RER (Resting Energy Requirement) is the number of calories a dog needs at complete rest, while MER (Maintenance Energy Requirement) accounts for normal activity levels. For weight gain, dogs typically need 10-20% more calories than their MER.

2. How Does the Calculator Work?

The calculator uses the following formulas:

Where:

• \( RER \) — Resting Energy Requirement (kcal/day)
• \( MER \) — Maintenance Energy Requirement (kcal/day)
• Activity Factor — 1.2 (sedentary) to 1.5 (active)
• Weight Gain Calories — Typically 10% above target MER

3. Importance of Proper Caloric Intake

Details: Proper caloric intake is essential for healthy weight gain. Too rapid weight gain can be unhealthy, while insufficient calories won't achieve the desired weight increase.

4. Using the Calculator

Tips: Enter your dog's current weight in kg, select activity level, and optionally enter a target weight for weight gain recommendations.

5. Frequently Asked Questions (FAQ)

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

Q2: What if my dog is underweight?
A: Consult a vet first to rule out medical causes. Then gradually increase calories by 10-20% above MER.

Q3: Are there special foods for weight gain?
A: High-calorie, nutrient-dense foods or veterinary weight-gain formulas may be recommended for underweight dogs.

Q4: How often should I weigh my dog during weight gain?
A: Weekly weigh-ins are recommended to monitor progress and adjust caloric intake as needed.

Q5: When should I stop increasing calories?
A: When your dog reaches ideal body condition (you can feel ribs with slight fat cover, visible waist).
