Cocker Spaniel portions by weight
| Adult weight | RER | Daily target | Kibble / day | Cups / day | Per meal (×2) | Raw / day |
|---|---|---|---|---|---|---|
| 11.0 kg | 423 kcal | 676 kcal | 165 g | 1.6 | 82 g | 275 g |
| 13.0 kg | 479 kcal | 767 kcal | 187 g | 1.9 | 93 g | 325 g |
| 15.0 kg | 534 kcal | 854 kcal | 208 g | 2.1 | 104 g | 375 g |
Neutered adult (×1.6), kibble at 370 kcal/100 g, 10% treat allowance removed. Raw at 2.5% of body weight (size-correct rate). Cups ≈ grams ÷ 100 (typical kibble — weigh in grams for accuracy).
Worked example: a 13.0 kg Cocker Spaniel
A 13.0 kg adult Cocker Spaniel (neutered): RER 479 × 1.6 = 767 kcal − 77 kcal treats ÷ 3.7 kcal/g = 187 g — that is 93 g per meal, twice a day. The same arithmetic runs in the calculator above: change the weight or the life stage and every number follows.
Cocker Spaniel puppy feeding by age
| Age | Factor | Meals / day | Note |
|---|---|---|---|
| Under 4 months | ×3.0 | 3–4 | On current weight — weigh every 2 weeks |
| 4–8 months | ×3.0 → ×2.0 (taper) | 3–4 | Factor falls smoothly — weigh every 2 weeks |
| 8–12 months | ×2.0 | 3 | 3 meals; 2–3 from 6 months |
| 12 months to adult | ×1.6–1.8 | 2 | Adult factor from 12–14 months |
Factors multiply RER on the puppy's current weight, not adult weight. Large and giant breeds keep the growth factors until 12–14 months.
Feeding notes for the Cocker Spaniel
The medium class is where the standard model fits best: 1.6× for a neutered adult, two meals, ±10% adjustments by body condition. Most medium dogs hold condition on the default within one adjustment cycle.
What makes feeding a Cocker Spaniel different: Cockers are food-motivated and prone to weight gain, and they beg with professional skill. The treat budget is the usual leak — measure meals, count every biscuit inside the daily number, and weigh monthly before the waist disappears.
Health, treats and the senior years: Cockers are prone to pancreatitis as well as weight gain, so fatty treats and table scraps are a worse idea for this breed than for most. In the senior years, keep the diet lean and the ears clean — and if the appetite changes suddenly, that is a vet visit, not a new food.
Training, treats and everyday feeding: Cockers are famously food-motivated and famously good at begging, so the whole household has to agree on one measured portion and one treat budget. A puzzle feeder slows down a Cocker that inhales its bowl, and training treats should come from the meal ration itself — a day of retrieving rewards adds up fast.
Weight & condition for the Cocker Spaniel: Cockers are food-motivated and prone to weight gain, and they beg with professional skill — the treat budget is the usual leak. Measure meals, count every biscuit inside the daily number, and weigh monthly before the waist disappears. Spayed and neutered Cockers are the highest-risk group: start on the inactive factor if walks are short.
Body condition check: Judge the portion by the dog, not just the table: on the 9-point body condition scale, aim for 4–5 — ribs easily felt under a thin fat cover, a waist visible from above, a tuck from the side. If you can't feel the ribs, feed 10% less than the table even if the weight looks right; if ribs show, feed 10% more.
Puppies of this size class reach adult factors at about 12–14 months; until then, growth portions follow the puppy factors (×3.0 under 4 months, tapering to ×2.0 by 8 months) on current weight, recalculated every two weeks. Individual dogs vary by up to ±50% from any formula — the scale and your hands on the ribs outrank this table.

Cocker Spaniel feeding questions
How much food should a Cocker Spaniel eat per day?
Across the full adult weight range (11–15 kg), a Cocker Spaniel needs about 676–854 kcal/day — 165–208 g of typical kibble (370 kcal/100 g) after the 10% treat allowance is removed — depending on weight, sex and activity. A typical adult at the middle of the range (13.0 kg) needs about 767 kcal/day, roughly 187 g, split over 2 meals.
How many meals a day should a Cocker Spaniel eat?
Two meals a day is the rule for a Cocker Spaniel: about 93 g per meal from a daily total of 187 g (767 kcal) for a 13.0 kg adult. A cocker that trains or retrieves all day can eat a quarter of its daily calories in rewards, so training treats must come out of the ration. The whole household must agree on the two meals and the treat budget — one person slipping extras undoes everything.
How many cups of food does a Cocker Spaniel need per day?
About 187 g/day is roughly 1.9 cups at the typical density of 100 g per cup — but cups vary by up to 40% between kibbles, so weigh the grams once and the question disappears. A cup is a volume; grams are the portion. Split over two meals that is about 0.9 cups per meal — still worth weighing once, because your cup and your kibble are not the standard ones.
How do I switch a Cocker Spaniel to a new food?
Over 7 days: 25% new food for 2 days, 50% for 2 days, 75% for 2 days, then 100% — keeping the total daily grams at the number on this page throughout. If stools loosen, hold at the current mix for an extra day or two before moving on. If your dog has a sensitive stomach, allow 10–14 days instead of 7.
How much should a Cocker Spaniel puppy eat?
Medium puppies reach adult factors at about 12–14 months. Growth portions follow ×3.0 (under 4 months) tapering to ×2.0 by 8 months, on current weight, recalculated every two weeks; growth spurts change the answer monthly.
How much raw food does a Cocker Spaniel need?
At the size-correct BARF rate of 2.5% of ideal body weight, a 13.0 kg Cocker Spaniel eats about 325 g of raw food per day — split 70% muscle meat, 10% raw edible bone, 5% liver, 5% other organ, 10% vegetables and fruit on the BARF model.
How does feeding a Cocker Spaniel change as they age?
From about 12–14 months a Cocker Spaniel counts as fully adult; the senior shift usually arrives years later, when activity and muscle mass fall. The calculator's senior factor (×1.4 instead of ×1.6) trims a 13.0 kg Cocker Spaniel from 767 to about 671 kcal/day — roughly 163 g of typical kibble. Make the change gradually and judge by body condition, not birthdays alone: a still-active older Cocker Spaniel may hold condition on the adult number.
Why does my Cocker Spaniel keep gaining weight?
Because the breed begs brilliantly and the whole household gives in: everyone gives just one treat, and the Cocker accepts them all. Agree one measured daily portion (187 g for a 13.0 kg adult) and one treat budget, and keep the begging out of the kitchen. The waist disappears under the spaniel coat long before the scale moves, so feel the ribs weekly.
Do Cocker Spaniels need a low-fat diet?
Not by default — but Cockers are prone to pancreatitis, so fatty treats and table scraps are a worse idea for this breed than for most. Keep the diet lean, keep treats inside the 77 kcal/day budget for a 13.0 kg adult, and use the dog's own kibble as training rewards instead of rich biscuits.
