1. What is the RER Equation?

The RER (Resting Energy Requirement) equation calculates daily energy requirement for mini puppies using body weight. It provides an estimate of the energy needed for basic metabolic functions at rest.

2. How Does the Calculator Work?

The calculator uses the RER equation:

Where:

• \( BW \) — Body weight in kilograms (kg)
• 70 — Constant coefficient
• 0.75 — Exponential factor for metabolic scaling

Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate, with smaller animals having higher metabolic rates per unit of body weight.

3. Importance of RER Calculation

Details: Accurate RER estimation is crucial for determining appropriate food portions for mini puppies, ensuring proper growth and development while preventing obesity or malnutrition.

4. Using the Calculator

Tips: Enter body weight in kilograms. The value must be valid (weight > 0). This calculation is specifically designed for mini puppy breeds.

5. Frequently Asked Questions (FAQ)

Q1: What is RER used for?
A: RER (Resting Energy Requirement) is used to calculate the basic energy needs of animals at rest, which serves as the foundation for determining daily caloric requirements.

Q2: How does this relate to Royal Canin food?
A: The RER calculation helps determine the appropriate amount of Royal Canin Mini Puppy food needed to meet your puppy's daily energy requirements.

Q3: Are there activity factors to consider?
A: Yes, RER represents resting requirements. For active puppies, additional factors may need to be applied to account for growth and activity levels.

Q4: How often should I recalculate RER?
A: RER should be recalculated regularly as your puppy grows and gains weight, typically every 2-4 weeks during the first year.

Q5: Is this calculation breed-specific?
A: While the calculation is generally applicable, it's particularly designed for mini puppy breeds that have different metabolic needs compared to larger breeds.
