About the Rottweiler
Rottweilers are powerful working dogs with moderate-to-high energy needs. Males are typically 50–60 kg, females 35–48 kg.
Typical adult weight: 35–60 kg. This range is important — a Rottweiler at the lower end of the weight range needs significantly fewer calories than one at the upper end.
How many calories does a Rottweiler need?
We calculate calorie needs using the veterinary RER formula: 70 × weight(kg)⁰·⁷⁵, then multiply by a lifestyle factor. For a typical neutered adult Rottweiler, the lifestyle multiplier is approximately ×1.8.
| Weight | Daily kcal (neutered adult) | Dry kibble (3,400 kcal/kg) |

| 15 kg | 960 kcal | 282g / 2.4 cups |
| 20 kg | 1,192 kcal | 350g / 2.9 cups |
| 25 kg | 1,409 kcal | 414g / 3.5 cups |
| 30 kg | 1,615 kcal | 475g / 4.0 cups |
| 35 kg | 1,813 kcal | 533g / 4.4 cups |
| 40 kg | 2,004 kcal | 589g / 4.9 cups |
Practical feeding tips for Rottweilers
- Weigh the food: Use a kitchen scale rather than a scoop — cup measurements are inaccurate and can vary by 20–30% depending on kibble size.
- Split into 2 meals: Most adult dogs do best with two meals per day. This reduces the risk of bloat (especially important for large breeds) and keeps blood sugar stable.
- Count treats: Treats should make up no more than 10% of daily calories. If your Rottweiler gets regular treats, subtract their calorie value from the daily food portion.
- Recalculate every few months: Body weight and lifestyle change. Recalculate whenever your dog's weight changes by more than 5%.
- Monitor body condition: You should be able to feel your Rottweiler's ribs with light pressure but not see them. A visible waist from above is a good sign of healthy weight.
