How Much to Feed a Clumber Spaniel
Clumber Spaniels are heavyset, efficient eaters with moderate metabolisms who thrive on structured meal plans and joint-supporting nutrition. Using the veterinary RER/MER formula, an adult Clumber Spaniel of about 63 lbs needs roughly 2163 kcal per day — around 569 g (5.7 cups) of typical dry food. The calculator below is pre-set for the Clumber Spaniel: adjust the weight, life stage and food type to match your dog.
Clumber Spaniel portion calculator
Veterinary RER/MER formula — daily calories, grams and cups.
RER 865 kcal × 2.5 (active / working) = 2163 kcal, at 380 kcal/100g. Estimates for healthy pets — always confirm with your veterinarian.
Large breeds such as the Clumber Spaniel need fewer calories per pound than small dogs — metabolic rate scales with body surface, not weight, which is exactly what the RER exponent (kg^0.75) captures. At 63 lbs that works out to about 2163 kcal per day. Resist rounding portions up “because he's big”: excess weight is the single largest controllable risk factor for hip and elbow problems in large dogs.
A Clumber Spaniel in good condition weighs about 63 lbs (28.6 kg). The RER formula (70 × kg^0.75) gives 865 kcal at rest, and the active / working factor of 2.5 brings the daily target to 2163 kcal — approximately 5.7 cups of standard 380 kcal/100g kibble split into 2 meals of about 285 g each.
These numbers are a starting point, not a prescription. The calculator supports every life stage (puppy, puppy, adult, neutered/spayed, adult, intact, active / working, senior, weight loss plan) — a puppy can need two to three times the adult allowance, while a senior or a dog on a weight-loss plan needs noticeably less. Recheck the numbers after any change in weight, activity, food brand or neutering status, and always transition between foods gradually over 7–10 days. For medical conditions, pregnancy or lactation, follow your veterinarian's feeding plan instead.
Frequently asked questions
How much food should a Clumber Spaniel eat per day?
A typical adult Clumber Spaniel weighing 63 lbs needs about 2163 kcal per day (active / working), which is roughly 569 grams — about 5.7 cups — of standard dry food, split into 2 meals.
How is the Clumber Spaniel's daily portion calculated?
We use the standard veterinary formula: Resting Energy Requirement (RER) = 70 × (weight in kg)^0.75, then multiply by a life-stage factor. For a 28.6 kg Clumber Spaniel, RER is 865 kcal, and the active / working factor of 2.5 gives 2163 kcal per day.
How many times a day should I feed my Clumber Spaniel?
2 meals per day is the standard recommendation for a active / working dog — about 1081 kcal (285 g of dry food) per meal. Puppies and kittens need 3–4 smaller meals instead.
My Clumber Spaniel seems hungry after meals — should I feed more?
Begging is not a reliable hunger signal, especially in food-motivated breeds. Judge by body condition instead: you should feel ribs easily under a thin fat layer. If your Clumber Spaniel is truly losing weight at 2163 kcal per day, increase portions by ~10% and re-weigh in two weeks.
