Puppy Food Amount
Estimate how much to feed a growing puppy by age and target adult size.
About Puppy Food Amount
A growing puppy needs about three times the resting energy of its expected adult weight while it is small, decreasing to adult levels by about one year of age. Underfeeding a puppy can stall growth, while overfeeding large breeds risks rapid growth and joint problems, so portion matters as much as food quality.
Formula
Puppy Food Amount
Puppy energy ≈ 3 x adult RER, scaled down as the puppy matures; grams = kcal / 3
- RER
- resting energy of the expected adult weight
