How do I calculate food portions and feeding frequency for a puppy?

Quick answer

Puppies (2–6 months old) are in their growth stage, so they should eat 3–4 smaller meals a day to prevent low blood sugar. As a rough guideline, the daily total is about 3–4% of the puppy's body weight, split across meals. If stool is soft, you may be overfeeding; if it's hard like little pellets, you may be underfeeding.
