How much to feed a Welsh Springer Spaniel
A neutered adult Welsh Springer Spaniel at 45 lb needs about 1076 kcal a day, which is 3 cups of a 369 kcal/cup food; at the 35 lb end of the breed's range it is 891 kcal, or 2½ 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.

Welsh Springer Spaniel feeding table by weight and life stage
Each row is a Welsh Springer 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 |
|---|---|---|---|---|---|---|---|
| 35 lb (15.9 kg) | 557 | 891 kcal | 2½ | 1002 kcal | 2¾ | 779 kcal | 2 |
| 38 lb (17.2 kg) | 592 | 947 kcal | 2½ | 1066 kcal | 3 | 829 kcal | 2¼ |
| 40 lb (18.1 kg) | 615 | 985 kcal | 2¾ | 1108 kcal | 3 | 862 kcal | 2¼ |

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 45 lb Welsh Springer Spaniel the gap between the intact and neutered columns is 134 kcal a day, roughly 0.4 cups. A dog that is already carrying extra weight should start from the inactive column (941 kcal at 45 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 45 lb and 1076 kcal, 3 cups is about 288 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 Welsh Springer Spaniel puppy feeding chart.
How the Welsh Springer Spaniel compares
Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 45 lb Welsh Springer Spaniel needs 24 kcal per pound; a 49 lb Australian Cattle Dog needs 1146 kcal (23 per lb), a 44 lb Keeshond needs 1058 kcal (24 per lb), a 40 lb Soft Coated Wheaten Terrier needs 985 kcal (25 per lb). The breed ranks 65 of 132 by weight on this site.
