How Much Should I Feed My Puppy? By Age and Weight

Researched & fact-checked Updated 2026-08-20 4 min read Feeding a puppy

Start with the bag chart for expected adult weight, then adjust by body condition every two weeks. Here is how to read the numbers and when to change them.

Feed to the bag chart for your puppy's expected adult weight, then adjust every two weeks by how the puppy actually looks and feels. The chart gets you into the right range; body condition is what tells you whether that range is right for this particular dog.

Why the chart is keyed to adult weight, not today's weight

A Labrador puppy at 12 weeks and a fully grown Beagle can weigh the same thing and need very different amounts of food. Growth demand is driven by how much dog still has to be built, not by how much dog is there today. That is why puppy food charts have a column for "expected adult weight" and a row for current age, and why using the wrong column is the most common feeding mistake people make.

If you do not know the adult weight — a shelter mix, an unclear parentage — use your vet's estimate, or read how big your puppy will get for the estimation methods, and re-check the estimate at each vet visit.

Reading a puppy food chart

Every brand's numbers differ because the food's calorie density differs, so never carry a cup count from one bag to another. What is consistent is the shape:

StageRoughly what happens to the daily amount
8–16 weeksClimbs steadily, week by week
4–6 monthsPeaks, often the highest daily volume of their life
6–9 monthsPlateaus, then starts to fall for small and medium breeds
9–12 monthsFalls toward adult maintenance in small and medium breeds
12–24 monthsLarge and giant breeds taper last

Two practical notes. First, weigh the food on a kitchen scale rather than scooping — cup measurements of kibble vary by 20 percent or more depending on how you fill them, and that error compounds over months. Second, the daily amount is divided across the day's meals, not added to each of them. The number of meals is a separate question, covered in the puppy feeding schedule.

For a starting figure keyed to your puppy's weight, age bracket and food, the Food Portion Calculator has puppy brackets built in.

The check that actually decides the number: body condition

Every two weeks, put your hands on the puppy.

Weigh at the same time of day on the same scale if you can. Puppies should gain steadily; a plateau in a puppy under six months, or any weight loss, is a reason to call the vet rather than to double the food.

Treats, chews and table scraps

Ten percent of daily calories is the working ceiling for everything that is not a meal, and puppy training runs through treats quickly. Three fixes:

  • Break treats into pea-sized pieces. A puppy is rewarded by the event, not the volume.
  • Use part of the daily kibble ration as training currency, especially for easy reps at home. Save the high-value stuff for hard environments.
  • Count chews. A long-lasting chew can carry a meaningful share of a small puppy's daily calories.

Freeze-dried single-ingredient training treats are the usual pick here because they break down small and are low-calorie per piece. See the wider range at dog treats.

Common situations that change the number

  • Switching foods. Move over 7 to 10 days, mixing increasing amounts of the new food in, and recalculate the portion from the new bag's chart.
  • A big activity change. More exercise raises need somewhat, but do not free-feed an active puppy — adjust and re-check condition.
  • Loose stool after an increase. Back off to the previous amount for a few days, then increase more gradually. Diarrhea lasting beyond a day in a young puppy warrants a vet call.
  • Large-breed growth. These puppies need a controlled growth curve and a food formulated for it, which is a separate decision covered in large-breed puppy food.

What to do this week

Find the expected adult weight, pull the number off your bag's chart, weigh it on a kitchen scale, split it across the day's meals, and put a recurring reminder in your phone for a two-week body-condition check. Then stop adjusting between checks — the single biggest source of feeding chaos is changing the amount every time the puppy acts hungry.

Frequently asked questions

Should I feed my puppy by current weight or expected adult weight?

Expected adult weight, which is what almost every puppy bag chart is built around. Feeding a large-breed puppy by their current weight underfeeds them badly at eight weeks and overfeeds them at nine months. If you do not know the adult weight, ask your vet for an estimate at the next visit.

Is it better to slightly underfeed or overfeed a growing puppy?

Lean is safer than heavy. Excess weight during the growth phase is associated with orthopaedic problems later, particularly in large and giant breeds, and there is no benefit to a fast growth curve. A puppy you can feel the ribs on, with a visible waist, is where you want to be — but a puppy losing weight or with visible ribs and spine needs a vet, not more food.

Why does my puppy always act hungry?

Most puppies act hungry regardless of how much they have eaten, so behaviour at the bowl is a poor guide to portions. Judge by body condition and the growth curve instead. If appetite comes with weight loss, diarrhea, or a suddenly ravenous change from normal, that is worth a vet call.

Do treats count toward my puppy's daily food?

Yes, and during training they add up fast. Keep treats to roughly ten percent of daily calories and subtract that from the meals rather than adding it on top. Breaking training treats into pea-sized pieces buys you far more repetitions for the same calories.
