How much to feed a English Cocker Spaniel
A neutered adult English Cocker Spaniel at 34 lb needs about 872 kcal a day, which is 2¼ cups of a 369 kcal/cup food; at the 28 lb end of the breed's range it is 754 kcal, or 2 cups. That is the maintenance figure before treats, from the resting energy requirement formula and the Merck Veterinary Manual's factor of 1.6 for a neutered adult.

English Cocker Spaniel feeding table by weight and life stage
Each row is a English Cocker Spaniel at that weight. Columns are the Merck factors: a neutered adult (×1.6), an intact adult (×1.8) and a dog that is inactive or gains weight easily (×1.4). Cups assume 369 kcal per cup, the label figure for Purina Pro Plan Complete Essentials Shredded Blend Chicken & Rice (adult dry); change it to your bag's number on the sizer.
| Weight | RER | Neutered adult | Cups | Intact adult | Cups | Inactive / weight-prone | Cups |
|---|---|---|---|---|---|---|---|
| 28 lb (12.7 kg) | 471 | 754 kcal | 2 | 848 kcal | 2¼ | 659 kcal | 1¾ |
| 30 lb (13.6 kg) | 496 | 794 kcal | 2¼ | 893 kcal | 2½ | 694 kcal | 2 |
| 31 lb (14.1 kg) | 508 | 813 kcal | 2¼ | 915 kcal | 2½ | 712 kcal | 2 |

Why the number is lower than the bag says
Bag feeding guides are written for an active, intact adult and often run above the neutered-maintenance figure; for a 34 lb English Cocker Spaniel the gap between the intact and neutered columns is 109 kcal a day, roughly 0.3 cups. A dog that is already carrying extra weight should start from the inactive column (763 kcal at 34 lb) and be weighed every two weeks. Treats and chews count: a single dental chew can be 70–100 kcal, which adds up faster than it looks across a week.
Formulas get a healthy adult into the right range; body condition keeps it there. Ribs should be easy to feel under a thin layer of fat, and the dog should have a visible waist from above. If that is not the case after four weeks, adjust by about 10% and re-check — and ask your vet before changing a dog with a medical condition, a pregnant or nursing female, or a working dog in season.
Grams and meals
At 34 lb and 872 kcal, 2¼ cups is about 216 g a day of a 96 g/cup kibble — a kitchen scale is more repeatable than a scoop. Split into two meals for an adult. Puppies eat more per pound and more often: see the English Cocker Spaniel puppy feeding chart.
How the English Cocker Spaniel compares
Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 34 lb English Cocker Spaniel needs 26 kcal per pound; a 35 lb Lagotto Romagnolo needs 891 kcal (25 per lb), a 40 lb Whippet needs 985 kcal (25 per lb), a 55 lb Xoloitzcuintli needs 1250 kcal (23 per lb). The breed ranks 53 of 132 by weight on this site. Females of the breed top out around 32 lb, which is 833 kcal a day neutered.
