Feeding by breed and weight / Herding group
How much to feed a Pembroke Welsh Corgi
A neutered adult Pembroke Welsh Corgi at 31 lb needs about 813 kcal a day, which is 2¼ cups of a 369 kcal/cup food; at the 24 lb end of the breed's range it is 671 kcal, or 1¾ 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.
Pembroke Welsh Corgi feeding table by weight and life stage
Each row is a Pembroke Welsh Corgi 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 |
|---|---|---|---|---|---|---|---|
| 24 lb (10.9 kg) | 420 | 671 kcal | 1¾ | 755 kcal | 2 | 587 kcal | 1½ |
| 26 lb (11.8 kg) | 445 | 713 kcal | 2 | 802 kcal | 2¼ | 624 kcal | 1¾ |
| 28 lb (12.7 kg) | 471 | 754 kcal | 2 | 848 kcal | 2¼ | 659 kcal | 1¾ |
| 29 lb (13.2 kg) | 483 | 774 kcal | 2 | 870 kcal | 2¼ | 677 kcal | 1¾ |
| 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 31 lb Pembroke Welsh Corgi the gap between the intact and neutered columns is 102 kcal a day, roughly 0.3 cups. A dog that is already carrying extra weight should start from the inactive column (712 kcal at 31 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 31 lb and 813 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 Pembroke Welsh Corgi puppy feeding chart.
How the Pembroke Welsh Corgi compares
Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 31 lb Pembroke Welsh Corgi needs 26 kcal per pound; a 30 lb Cocker Spaniel needs 794 kcal (26 per lb), a 31 lb French Bulldog needs 813 kcal (26 per lb), a 32 lb Dachshund (Standard) needs 833 kcal (26 per lb). The breed ranks 22 of 49 by weight on this site. Females of the breed top out around 28 lb, which is 754 kcal a day neutered.
