How much to feed a Soft Coated Wheaten Terrier

A neutered adult Soft Coated Wheaten Terrier at 40 lb needs about 985 kcal a day, which is 2¾ 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.

Soft Coated Wheaten Terrier feeding table by weight and life stage

Each row is a Soft Coated Wheaten Terrier 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.

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 40 lb Soft Coated Wheaten Terrier the gap between the intact and neutered columns is 123 kcal a day, roughly 0.3 cups. A dog that is already carrying extra weight should start from the inactive column (862 kcal at 40 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 40 lb and 985 kcal, 2¾ cups is about 264 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 Soft Coated Wheaten Terrier puppy feeding chart.

How the Soft Coated Wheaten Terrier compares

Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 40 lb Soft Coated Wheaten Terrier needs 25 kcal per pound; a 45 lb Standard Schnauzer needs 1076 kcal (24 per lb), a 40 lb Kerry Blue Terrier needs 985 kcal (25 per lb), a 44 lb Keeshond needs 1058 kcal (24 per lb). The breed ranks 62 of 132 by weight on this site. Females of the breed top out around 35 lb, which is 891 kcal a day neutered.
