How we calculate calories
We use the standard veterinary RER (Resting Energy Requirement) formula: 70 × (weight in kg)^0.75, multiplied by an activity factor. For a 25-lb Cocker Spaniel at moderate activity, that's approximately 606 kcal per day. Puppies need 2x maintenance; seniors typically 0.8x.
