Resting energy at that weight is about 1490 kcal per day. The Merck neutered-adult factor of 1.6 puts maintenance near 2384 kcal before activity is added. The dog food calculator on this page uses that same resting-energy formula, then applies the activity and size adjustments from the main dog food calculator.

Reading the portions

Compared with other single-size giant breeds, that neutered-adult portion is 195 kcal higher than the 2189 kcal for an average giant breed at 116 lb.

Portions are a starting estimate. Leonberger individuals can vary by body condition, neuter status, and how much they work. Adjust the bowl from what you see on the ribs, not from the table alone.
