1. What is the DER Formula?

The DER (Daily Energy Requirement) formula calculates the appropriate calorie intake for dogs needing to lose weight. It's based on the dog's ideal weight rather than current weight to determine the proper caloric restriction.

2. How Does the Calculator Work?

The calculator uses the DER formula:

Where:

• \( Ideal Weight \) — The target healthy weight for your dog (kg)
• \( 0.75 \) — Exponent accounting for metabolic scaling
• \( 0.8 \) — Multiplier for weight loss calorie restriction

Explanation: The formula calculates the resting energy requirement based on ideal body weight and applies a 20% reduction for safe weight loss.

3. Importance of Weight Management

Details: Proper weight management is crucial for canine health, reducing risks of joint problems, diabetes, heart disease, and increasing overall lifespan and quality of life.

4. Using the Calculator

Tips: Enter your dog's ideal weight in kilograms as determined by your veterinarian. This should be a healthy target weight, not necessarily the current weight.

5. Frequently Asked Questions (FAQ)

Q1: How often should I recalculate my dog's calorie needs?
A: Recalculate every 2-4 weeks as your dog loses weight, or consult with your veterinarian for personalized guidance.

Q2: What if my dog isn't losing weight on this calorie amount?
A: Consult your veterinarian. They may recommend further calorie reduction or investigate other health issues affecting weight loss.

Q3: Should I adjust for activity level?
A: This formula provides a baseline for weight loss. Highly active dogs may need slight adjustments, but always consult your vet before making changes.

Q4: How quickly should my dog lose weight?
A: Safe weight loss is typically 1-2% of body weight per week. Rapid weight loss can be dangerous for dogs.

Q5: Are there special considerations for senior dogs?
A: Yes, senior dogs may have different metabolic needs and health considerations. Always work with your veterinarian for weight management in older dogs.
