Brittany owners often ask how much to feed their dog each day. Adult Brittanys typically weigh between 10 and 25 kg, though individual metabolism, activity, and health status all influence true calorie needs. This Brittany feeding calculator uses veterinary RER and MER formulas to estimate daily calories and food portions based on your dog's current weight, body condition, activity level, and life stage. Whether your Brittany is a growing youngster, active adult, or senior companion, portion guidance should be adjusted as weight and energy change. Use the results alongside regular body condition checks and your veterinarian's advice—especially if your Brittany has breed-related health considerations or is on a weight-management plan.

Brittany Feeding Tips
Weigh your Brittany monthly and adjust portions if body condition drifts from ideal.
Split daily calories into two measured meals to support steady energy and digestion.
Choose a complete diet appropriate for your Brittany's life stage (puppy/kitten, adult, or senior).
Track treats and table scraps—they can add 10–30% of daily calories for many Brittanys.
Increase portions gradually during growth or high activity; decrease slowly for weight loss.
Health Notes
Typical adult Brittany weight: 10–25 kg (medium dog).
Recalculate portions after significant weight change, spay/neuter, or activity shifts.
