Resting energy at that weight is about 644 kcal per day. The Merck neutered-adult factor of 1.6 puts maintenance near 1030 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 medium breeds, that neutered-adult portion is 156 kcal higher than the 874 kcal for an average medium breed at 34.1 lb.

Portions are a starting estimate. Australian Cattle Dog 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.
