RER Equation:
| From: | To: |
The RER (Resting Energy Requirement) equation estimates the daily caloric needs for dogs at rest. It provides a baseline for determining appropriate feeding amounts for Royal Canin dog food in Australia.
The calculator uses the RER equation:
Where:
Explanation: The equation calculates the resting energy requirements based on the dog's metabolic body weight, which more accurately reflects energy needs than simple linear calculations.
Details: Accurate RER estimation is crucial for determining appropriate feeding amounts, maintaining optimal body condition, and preventing obesity or malnutrition in dogs.
Tips: Enter the dog's body weight in kilograms. The value must be valid (weight > 0). This calculation provides the resting energy requirement which serves as a baseline for determining actual feeding amounts.
Q1: What is RER used for?
A: RER (Resting Energy Requirement) provides the baseline caloric needs for a dog at rest, which is then multiplied by factors based on activity level, life stage, and health status to determine actual daily caloric requirements.
Q2: How does RER differ from MER?
A: MER (Maintenance Energy Requirement) includes additional factors for activity and is typically 1.2-1.8 times the RER, depending on the dog's lifestyle and condition.
Q3: Is this calculation suitable for all dog breeds?
A: While the RER formula works for most dogs, some breeds may have different metabolic rates. Always consult with a veterinarian for breed-specific nutritional advice.
Q4: How often should I recalculate my dog's RER?
A: Recalculate whenever your dog's weight changes significantly, or every 3-6 months as part of regular health monitoring.
Q5: Can I use this calculation for puppies?
A: Puppies have higher energy requirements. The RER calculation provides a baseline, but growing puppies typically need 2-3 times the RER depending on age and breed.
