I go by 2.5% of expected adult weight and then adjust as needed. A very young puppy would need 10% of it’s weight per day, but an almost grown puppy would only need 3% of it’s adult weight. And a pup with a slower metabolism would only need 2% of it’s weight as it approached adulthood. I find it easier to start based on expected adult weight and adjust regularly according to body condition.
