Resting energy at that weight is about 158 kcal per day. The Merck neutered-adult factor of 1.6 puts maintenance near 253 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

Portions are a starting estimate. Russian Toy 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.
