Great Dane: healthy weight & calories
A healthy adult Great Dane usually weighs 45 to 70 kg (99.2 to 154.3 lb). That is a wide range because frame size varies a lot even within one breed, so how they feel under your hands matters more than the number alone.
Estimated for a Great Dane at 57.5 kg, a healthy weight in the middle of the breed range. Resting energy is 70 × weight0.75 kcal; the multiplier below scales it up for how much they move and whether they are desexed.
| Activity | Desexed | Entire |
|---|---|---|
| Mostly restsa few short potty walks | 1,754 kcal | 2,046 kcal |
| Short daily walks20 to 30 minutes total | 2,046 kcal | 2,339 kcal |
| Active most days45 to 60 minutes, some play | 2,339 kcal | 2,631 kcal |
| Very activeruns, hikes or dog sport | 2,631 kcal | 2,923 kcal |
Puppies get roughly twice their resting energy while growing, about 2,923 kcal a day at this weight, but puppy needs change every few weeks so this is a starting point, not a fixed number. Seniors typically need about 10% less than an adult at the same activity level.
Giant breeds age faster, with seniors from about 6 years, and extra weight loads joints that are already working hard. Keep exercise steady and low impact, and avoid repeated jumping.
Studies of dogs a similar size to a Great Dane found overweight dogs had a shorter median life span than lean ones, by 0.3 to 0.6 years (Salt et al. 2019). That is an association from observational data, not a promise, but it is one of the largest studies of its kind.
