1. What is the RER Formula?

The RER (Resting Energy Requirement) formula calculates the basic caloric needs of a dog at rest. It's the foundation for determining daily feeding requirements based on weight, with adjustments for activity level and life stage.

2. How Does the Calculator Work?

The calculator uses the RER equation with activity multipliers:

Where:

• Weight — Dog's body weight in kilograms
• Activity Multiplier — Adjustment factor based on lifestyle:
  • 1.2 — Sedentary/Weight loss
  • 1.6 — Normal adult maintenance
  • 2.0 — Active/working dogs
  • 2.5 — Growing puppies

Explanation: The base RER is multiplied by factors that account for different energy needs based on activity level and life stage.

3. Importance of Proper Feeding

Details: Accurate feeding calculations help maintain ideal body condition, prevent obesity, and ensure proper nutrition for dogs at different life stages and activity levels.

4. Using the Calculator

Tips: Weigh your dog accurately. For obese dogs, use ideal weight rather than current weight. Adjust portions based on body condition score and weight changes.

5. Frequently Asked Questions (FAQ)

Q1: How often should I adjust my dog's food intake?
A: Re-evaluate every 2-4 weeks or when there are significant changes in weight, activity level, or life stage.

Q2: What if my dog is overweight?
A: Use the "Sedentary/Weight Loss" multiplier and consult your veterinarian for a weight loss plan.

Q3: Are there exceptions to this formula?
A: Yes, very small or very large breeds, pregnant/lactating females, and dogs with certain medical conditions may need special considerations.

Q4: How do I convert pounds to kilograms?
A: Divide weight in pounds by 2.205 to get kilograms (e.g., 20 lbs ÷ 2.205 = 9.07 kg).

Q5: Should I feed all the calories in food?
A: Remember to account for treats in the total daily calorie count (treats should be ≤10% of daily calories).
