Dog Calorie Needs Explained
Feeding your dog the correct amount is the single most important factor in their long-term health. This calculator uses the Resting Energy Requirement (RER) formula tailored by the World Small Animal Veterinary Association (WSAVA).
Factors Affecting Calorie Needs
- Neutering Status: Neutered/spayed dogs typically have lower metabolic rates and need fewer calories.
- Activity Level: A working farm dog may need 2-3x the calories of a "couch potato" dog.
- Life Stage: Puppies need massive amounts of energy for growth, often double that of an adult dog of the same weight.
Note: Always measure food by weight (grams) rather than volume (cups) for accuracy. Consult your vet before starting a weight loss program.
