Canine Weight Loss Formula:
| From: | To: |
The canine weight loss calculation determines the appropriate caloric intake (MER) for a dog to safely lose weight by multiplying the Resting Energy Requirement (RER) by 0.8. This creates a moderate caloric deficit for gradual, healthy weight loss.
The calculator uses two key formulas:
Where:
Explanation: The calculation first determines the dog's basic energy needs at rest (RER), then reduces this by 20% to create a safe caloric deficit for weight loss.
Details: Proper caloric restriction is essential for safe canine weight loss. Too rapid weight loss can cause health problems, while insufficient restriction won't achieve results. This calculation provides a scientifically-based starting point for weight management.
Tips: Enter your dog's current weight in kilograms. For best results, weigh your dog regularly and adjust food intake as needed. Always consult with your veterinarian before starting a weight loss program.
Q1: Why multiply RER by 0.8 for weight loss?
A: A 20% reduction from maintenance calories (0.8 multiplier) creates a safe, sustainable deficit that typically results in 1-2% body weight loss per week.
Q2: What if my dog isn't losing weight on this amount?
A: Individual needs vary. Consult your vet - you may need to adjust to 0.7×RER for dogs with severe obesity or metabolic conditions.
Q3: How often should I recalculate my dog's needs?
A: Recalculate every 10% of body weight lost, as energy requirements decrease with weight loss.
Q4: Can I use this for puppies?
A: No, this calculator is for adult dogs only. Puppies have different nutritional requirements for growth.
Q5: What about very active dogs?
A: Working or highly active dogs may need adjustments. Consult a veterinary nutritionist for these cases.
