1. What is RER for Dogs?

RER (Resting Energy Requirement) is the number of calories a dog needs at rest in a thermoneutral environment. For weight loss, we typically use 80% of RER.

2. How Does the Calculator Work?

The calculator uses the following equations:

Where:

• \( weight_{kg} \) — Dog's weight in kilograms
• 0.8 — Weight loss factor (80% of RER)

Explanation: The equation accounts for metabolic scaling where smaller animals have higher metabolic rates per unit of body weight.

3. Importance of Weight Management

Details: Maintaining ideal weight is crucial for dogs' health, reducing risk of arthritis, diabetes, and improving longevity.

4. Using the Calculator

Tips: Enter dog's weight in kg and age in years. For accurate results, weigh your dog regularly and adjust food portions accordingly.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculator suitable for all dog breeds?
A: While the formula works for most breeds, very large or small breeds may need adjustments. Consult your vet.

Q2: How often should I recalculate my dog's calorie needs?
A: Recalculate every time your dog loses 10% of body weight or monthly during weight loss programs.

Q3: What if my dog isn't losing weight on these calories?
A: Some dogs may need further reduction to 70% RER, but only under veterinary supervision.

Q4: Does age affect calorie requirements?
A: Senior dogs may need slightly fewer calories due to decreased activity, but the main factor is current weight.

Q5: Should I use this for puppies?
A: No, puppies have different nutritional requirements. This calculator is for adult dogs only.
