How many calories does a 50 kg Rottweiler need per day?

A neutered, moderately-to-highly active 50 kg Rottweiler typically needs approximately 2,000–2,500 calories per day as a starting estimate. An intact or very active working Rottweiler at the same weight may need closer to 2,500–3,000. Adjust based on monthly body condition score assessments.

Do Rottweilers need more food when they are working or in sport training?

Yes. Rottweilers in active working roles or regular sport training (protection, tracking, agility) burn meaningfully more calories than companion dogs with standard daily walks. A working Rottweiler may need 20–40% more calories than the companion estimate, depending on intensity and duration of work.

Why is my Rottweiler gaining weight even though I haven't changed his food?

Calorie needs change as dogs age, become less active (seasonally or due to health changes), or following spay/neuter. If nothing about the food has changed but the dog is gaining, the most likely explanation is that his actual calorie needs have decreased. Recalculate based on current weight and current activity level and discuss with your vet if weight gain continues.
