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.

Portions are a starting estimate. Black Russian Terrier 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.
