Resting energy at that weight is about 672 kcal per day. The Merck neutered-adult factor of 1.6 puts maintenance near 1075 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 large breeds, that neutered-adult portion is 247 kcal lower than the 1322 kcal for an average large breed at 59.2 lb.

Portions are a starting estimate. Welsh Springer Spaniel 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.
