How Much to Feed a Puppy (Feeding Chart by Weight & Age)
Free puppy feeding chart with daily calories, meal frequency, and grams per meal — anchored to WSAVA/AAHA lean-growth guidelines.

Quick answer
Feed your puppy the amount that maintains Body Condition Score 4/9 (lean) throughout growth, split across 3–4 meals per dayuntil six months. Use the bag's chart as a starting point, then adjust by ±10% every two weeks based on BCS. Always consult your veterinarian if growth seems off-pace.
Puppy feeding chart by weight and age
Quick reference for “how much to feed a puppy by weight and age” — use it as a starting point, then adjust by BCS every 2 weeks.
| Age | RER multiplier | Meals / day | Example (5 kg puppy) | Notes |
|---|---|---|---|---|
| 8–16 weeks | 3.0 × RER | 4 | ~700 kcal/day | Peak growth; toy breeds keep 4 meals for hypo risk |
| 4–6 months | 2.5 × RER | 3 | ~585 kcal/day | Growth rate slowing; large breeds stay lean |
| 6–9 months | 2.0 × RER | 2 | ~470 kcal/day | Most breeds at 2 meals; toy breeds 3 until 6 mo |
| 9–12 months | 1.8–2.0 × RER | 2 | ~420–470 kcal/day | Small breeds transition to adult food |
| 12–24 months | 1.4–1.6 × RER | 2 | Adult range | Large/giant breeds still growing; adult food later |
- Adjustment rule: change the daily amount by ±10%every 2 weeks based on Body Condition Score (don't chase day-to-day appetite swings).
- Your target: aim for BCS 4/9 (lean growth). If ribs are hard to feel and waist disappears, reduce portions.
- Formula: RER = 70 × current weight in kg^0.75. Example: 5 kg puppy → RER ≈ 234 kcal.

The single most important principle: lean growth, not fast growth
The Purina Lifetime Study (Kealy et al., JAVMA 2002) followed two groups of Labrador Retriever littermates from puppyhood: one group fed ad libitum, the other fed 25% less to maintain a lean BCS. The lean-fed dogs lived a median 1.8 years longer, developed visible osteoarthritis significantly later, and required treatment for chronic disease later in life. The intervention started in puppyhood.
This is the dataset every modern feeding guideline is built around, and it is why both WSAVA and AAHA prioritise the prevention of juvenile overweight over the treatment of adult obesity. Translation: a "fluffy" puppy is not a healthy puppy. A puppy at BCS 4/9 — slightly visible ribs through a thin fat cover, clear waist from above, athletic outline — is the target.
Meal frequency by age
Puppy stomachs are small and energy demands are high; one or two large meals per day cannot meet calorie needs in early life and create hypoglycaemia risk in toy breeds.
- Birth to 8 weeks: with the breeder/foster, normally 4–6 meals or free-fed alongside the dam.
- 8 to 12 weeks: 4 meals per day at home.
- 12 to 24 weeks: 3 meals per day.
- 6 months and older: 2 meals per day for life.
Toy breeds (under 4 kg adult target) should stay on 3 meals/day until at least 6 months because of hypoglycaemia risk. Large and giant breeds can move to 2 meals/day by 6 months but the total daily quantity is what matters.
How much (in grams) — the working method
Bag-printed feeding charts are starting points, not prescriptions. They are calibrated to a population average; your puppy is an individual. The working method:
- Find the bag's recommended daily quantity for current weight and projected adult weight.
- Divide it across the day's meals.
- Weigh the food, don't scoop it — a standard cup can vary by 30% in actual grams of kibble.
- Reassess BCS every two weeks and adjust ±10%.
- Weigh the puppy on the same scale, same day of the week.
Use our puppy calorie calculator to estimate Resting Energy Requirement (RER) for the puppy's current weight, then apply the standard puppy multiplier (3.0 × RER under 4 months, falling to 2.0 × RER by adulthood). Any bag whose recommendation is more than 25% above this estimate should be questioned.
Body Condition Score in a growing puppy
Puppies are scored on the same 9-point scale as adults, but the visual cues are deceptive. A healthy growing large-breed puppy looks leggy, gangly, and almost too lean — prominent hip points and a clearly visible waist are normal and should not be corrected by adding food. A healthy growing toy- or small-breed puppy looks rounder by proportion. Coat fluff hides BCS in puppy coats; use your hands.
For large- and giant-breed puppies, the published target throughout the growth phase is BCS 4/9 — visibly leaner than the average adult pet. This is the single most effective intervention against developmental orthopaedic disease in growing big dogs.
Large- and giant-breed special considerations
Rapid growth driven by excess calories or excess calcium is causally implicated in developmental orthopaedic disease (osteochondrosis, hip and elbow dysplasia). Clinically important rules:
- Use a diet labelled for large-breed puppy growth for any puppy with a projected adult weight over 25 kg. AAFCO statements distinguish this on the bag.
- Do not free-feed. Large-breed puppies on free-choice food grow too fast and load joints under-developed for the bone they're carrying.
- Do not supplement calcium. A balanced commercial puppy diet already meets needs; added calcium directly drives orthopaedic disease.
- Hold the diet steady through growth. Brand-switching mid-growth muddies the BCS feedback loop.
Small- and toy-breed special considerations
Toy puppies have the opposite problem: tiny stomachs, fast metabolisms, and real hypoglycaemia risk if meals are skipped. Keep 3–4 meals/day until at least 6 months. Don't withhold food during the day for house-training reasons — use scheduled potty breaks instead. Watch for early teeth crowding in brachycephalic toy breeds, where discomfort can drop intake and look like fussy eating when it's actually pain.
When to switch from puppy food to adult food
The switch depends on breed size, not a fixed birthday. Transition over 7–10 days by mixing increasing ratios of adult food.
| Breed size | Switch age | Signal |
|---|---|---|
| Toy / Small (< 10 kg adult) | 9–12 months | Growth plateau + BCS at target |
| Medium (10–25 kg adult) | 12 months | Near adult height + BCS 4–5/9 |
| Large (25–45 kg adult) | 12–18 months | Slowed height gain; vet confirms plates closing |
| Giant (> 45 kg adult) | 18–24 months | Growth plates closed on X-ray; BCS stable |
Red flags — see your vet
- Growth stalled or weight loss in a puppy under 12 months.
- Pot-bellied appearance with prominent ribs and dull coat — possible parasites or malabsorption.
- Persistent diarrhoea or vomiting at meal transitions.
- Lameness, reluctance to play, or asymmetric gait in a large-breed puppy — investigate early.
If any of these appear, see your vet rather than adjusting the diet yourself.
Puppy feeding FAQ
Common questions about “how much should I feed my puppy”, meal frequency, and transitioning to adult food.
- How much should I feed my puppy by weight?
- Use the RER formula (70 × current weight in kg^0.75) and multiply by a puppy factor: 3.0× under 4 months, ~2.5× at 4–8 months, and ~2.0× by 9–12 months. Convert the daily kcal to grams using the kcal/100g on your food's bag. Example: a 5 kg puppy at 4 months needs roughly 3.0 × 234 ≈ 700 kcal/day.
- How many times a day should I feed a puppy?
- Under 12 weeks, four meals per day. Twelve to 24 weeks, three meals. After six months, transition to two meals per day for life. Spreading meals reduces hypoglycaemia risk in toy breeds and supports steady growth.
- How do I know if I am overfeeding my puppy?
- Use Body Condition Score, not the bag. Ribs should be easily palpable under a light fat cover and a waist should be visible from above. If your puppy looks round or tubby, reduce portions by 10% and reassess in two weeks.
- Should I free-feed a puppy?
- No. Free-feeding makes portion control impossible, complicates house-training, and is strongly associated with overweight body condition by adulthood. Use measured meals.
- When can I switch from puppy food to adult food?
- Small breeds at 9–12 months, medium breeds at 12 months, large and giant breeds at 18–24 months. Switch when growth has plateaued and BCS is at target — not on a fixed birthday.
- My puppy always seems hungry — should I feed more?
- Probably not. Persistent food-asking is normal in many breeds (Labradors, Beagles, Goldens especially). Use the BCS chart and growth curve as your guide, not the dog's behaviour.
- Do large-breed puppies really need a special diet?
- Yes. Large- and giant-breed puppy foods are formulated with controlled calcium and energy density to support slow, even growth. Feeding adult or all-life-stages food during the large-breed growth window is associated with developmental orthopaedic disease.
