Feeding by breed and weight / Sporting group
How much to feed a Vizsla
A neutered adult Vizsla at 66 lb needs about 1433 kcal a day, which is 4 cups of a 369 kcal/cup food; at the 45 lb end of the breed's range it is 1076 kcal, or 3 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.
Vizsla feeding table by weight and life stage
Each row is a Vizsla 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 |
|---|---|---|---|---|---|---|---|
| 45 lb (20.4 kg) | 672 | 1076 kcal | 3 | 1210 kcal | 3¼ | 941 kcal | 2½ |
| 50 lb (22.7 kg) | 727 | 1164 kcal | 3¼ | 1309 kcal | 3½ | 1018 kcal | 2¾ |
| 56 lb (25.4 kg) | 792 | 1267 kcal | 3½ | 1426 kcal | 3¾ | 1109 kcal | 3 |
| 61 lb (27.7 kg) | 844 | 1351 kcal | 3¾ | 1520 kcal | 4 | 1182 kcal | 3¼ |
| 66 lb (29.9 kg) | 896 | 1433 kcal | 4 | 1613 kcal | 4¼ | 1254 kcal | 3½ |

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 66 lb Vizsla the gap between the intact and neutered columns is 180 kcal a day, roughly 0.5 cups. A dog that is already carrying extra weight should start from the inactive column (1254 kcal at 66 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 66 lb and 1433 kcal, 4 cups is about 384 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; for a deep-chested breed of this size, two or three smaller meals rather than one large one is the usual advice to reduce bloat risk, and your vet can say whether it applies to your dog. Puppies eat more per pound and more often: see the Vizsla puppy feeding chart.
How the Vizsla compares
Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 66 lb Vizsla needs 22 kcal per pound; a 71 lb Poodle (Standard) needs 1514 kcal (21 per lb), a 70 lb Australian Shepherd needs 1498 kcal (21 per lb), a 60 lb Siberian Husky needs 1335 kcal (22 per lb). The breed ranks 30 of 49 by weight on this site. Females of the breed top out around 55 lb, which is 1250 kcal a day neutered.
