Sussex Spaniel owners often ask how much to feed their dog each day. Adult Sussex Spaniels typically weigh between 10 and 25 kg, though individual metabolism, activity, and health status all influence true calorie needs. This Sussex Spaniel 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 Sussex Spaniel 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 Sussex Spaniel has breed-related health considerations or is on a weight-management plan.
