Feeding by breed and weight / Non-Sporting group
How much to feed a Shiba Inu
A neutered adult Shiba Inu at 22 lb needs about 629 kcal a day, which is 1¾ cups of a 369 kcal/cup food; at the 18 lb end of the breed's range it is 541 kcal, or 1½ 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.
Shiba Inu feeding table by weight and life stage
Each row is a Shiba Inu 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 |
|---|---|---|---|---|---|---|---|
| 18 lb (8.2 kg) | 338 | 541 kcal | 1½ | 609 kcal | 1¾ | 473 kcal | 1¼ |
| 19 lb (8.6 kg) | 352 | 563 kcal | 1½ | 634 kcal | 1¾ | 493 kcal | 1¼ |
| 20 lb (9.1 kg) | 366 | 585 kcal | 1½ | 659 kcal | 1¾ | 512 kcal | 1½ |
| 21 lb (9.5 kg) | 380 | 607 kcal | 1¾ | 683 kcal | 1¾ | 531 kcal | 1½ |
| 22 lb (10.0 kg) | 393 | 629 kcal | 1¾ | 707 kcal | 2 | 550 kcal | 1½ |

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 22 lb Shiba Inu the gap between the intact and neutered columns is 78 kcal a day, roughly 0.2 cups. A dog that is already carrying extra weight should start from the inactive column (550 kcal at 22 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 22 lb and 629 kcal, 1¾ cups is about 168 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 Shiba Inu puppy feeding chart.
How the Shiba Inu compares
Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 22 lb Shiba Inu needs 29 kcal per pound; a 20 lb Shetland Sheepdog needs 585 kcal (29 per lb), a 20 lb West Highland White Terrier needs 585 kcal (29 per lb), a 25 lb Beagle needs 692 kcal (28 per lb). The breed ranks 17 of 49 by weight on this site.
