How Much to Feed a Puppy: Weight-Based Feeding Chart
- Meals per day: 4x (under 3 months) → 3x (3–6 months) → 2x (6+ months)
- Caloric needs: 2–3x higher per kg than adult dogs during peak growth
- Starting point: Follow the feeding guide on your specific food's bag
- Adjust by: Body condition score — you should feel ribs but not see them
- Weigh monthly: Puppy growth is fast and portions need regular updating

Overfeeding a puppy can be just as harmful as underfeeding. Too many calories during growth promotes fat cell proliferation and rapid bone growth that can cause developmental joint problems, particularly in large breeds. Too few calories and the puppy fails to thrive, with consequences for brain development, immune function, and muscle mass. Getting the amount right requires understanding caloric density, feeding frequency, and how to use your puppy's body condition — not just a chart — as your primary guide.
Understanding Caloric Needs During Growth
Puppies have dramatically higher energy requirements per kilogram of body weight than adult dogs. A 10-week-old puppy needs roughly 2 to 3 times the calories per kilogram that the same dog will need as an adult. This is because growth — building new muscle, bone, organ tissue, and nervous system infrastructure — is metabolically expensive. As the puppy's growth rate slows, their caloric needs per kilogram drop toward adult maintenance levels.
The key metric used in veterinary nutrition is resting energy requirement (RER): RER (kcal/day) = 70 × (body weight in kg)^0.75. For puppies, a growth factor is applied. For puppies under 4 months, multiply RER by approximately 3.0. For 4–6 months, by 2.5. For 6–12 months, by 2.0. After 12 months (or at 80% of expected adult weight), begin transitioning toward adult maintenance.
In practice, you do not need to calculate this yourself — your puppy's food bag will provide feeding guidelines. But understanding the math helps you recognise when the guidelines may need adjustment.
Daily Feeding Amount Chart (Dry Kibble Approximate)
The following chart gives approximate daily dry kibble amounts for puppies at different ages and weight ranges. These are starting estimates based on a kibble with ~350–380 kcal per 100g — always cross-reference with your specific food's caloric density.
| Current Weight (kg) | 2–3 Months (g/day) | 3–4 Months (g/day) | 4–6 Months (g/day) | 6–12 Months (g/day) |
|---|---|---|---|---|
| 1–2 kg | 40–65 g | 35–55 g | 30–50 g | 25–45 g |
| 2–5 kg | 65–130 g | 60–120 g | 55–110 g | 50–100 g |
| 5–10 kg | 130–215 g | 120–200 g | 115–190 g | 100–175 g |
| 10–20 kg | 215–340 g | 200–320 g | 185–300 g | 170–280 g |
| 20–30 kg | 340–465 g | 320–440 g | 300–410 g | 280–380 g |
| 30+ kg | 465–600 g | 440–570 g | 410–540 g | 380–500 g |
Meal Frequency by Age
Young puppies have small stomachs and high energy demands — they cannot consume enough in two meals to sustain steady blood glucose through the day. Hypoglycemia (low blood sugar) is a real risk in tiny breeds under 3 months if meals are spaced too far apart.
| Age | Meals Per Day | Spacing |
|---|---|---|
| 6–12 weeks | 4 meals | Every 4–5 hours |
| 3–6 months | 3 meals | Morning, midday, evening |
| 6–12 months | 2–3 meals | Morning and evening (+ midday optional) |
| 12+ months | 2 meals | 12 hours apart |
How to Assess Your Puppy's Body Condition
Charts and calculations are starting points. Your puppy's body tells you whether the amount is right. Use the body condition score (BCS) system on a 1–9 scale, where 4–5 is ideal for a growing puppy:
- Too thin (BCS 1–3): Ribs, spine, and hip bones visible from a distance. No fat cover. Increase portions by 10% and recheck in 1–2 weeks.
- Ideal (BCS 4–5): Ribs easily felt but not prominently visible. Slight waist visible from above. Abdominal tuck present from the side. No change needed.
- Overweight (BCS 6–7): Ribs difficult to feel; slight excess fat cover. Waist barely discernible. Reduce portions by 10–15%.
- Obese (BCS 8–9): Cannot feel ribs. Rounded abdomen, no waist. Reduce portions significantly and consult your vet — obesity in puppyhood has lifelong health consequences.
Special Considerations for Large and Giant Breeds
Large breed puppies (adult weight over 25 kg) must not be overfed during growth. Excessive calorie intake causes too-rapid bone growth, which increases the risk of hip dysplasia, osteochondrosis (OCD), and hypertrophic osteodystrophy. The goal for large breed puppies is lean, steady growth — not maximum growth rate. Use a food specifically formulated for large breed puppies, and if anything, err slightly on the lower side of the recommended range while monitoring body condition score.
Wet Food vs Dry Kibble: Adjusting for Calories
Wet puppy food typically contains 70–80% moisture, meaning the caloric density per gram is much lower than dry kibble. A typical wet food provides around 80–100 kcal per 100g versus 350–380 kcal per 100g for dry kibble. If you feed wet food — or a mix of wet and dry — calculate total daily calories from both sources to avoid under- or over-feeding. The feeding charts on wet food tins will reflect this difference.
Whether you prefer dry, wet, or mixed feeding, Zooplus carries complete puppy nutrition lines from top brands, with detailed nutritional panels to help you calculate portions accurately. Subscribe and save options make it budget-friendly too.
- Feed 4 meals a day until 3 months, 3 meals until 6 months, then 2 meals from 6 months onward.
- Use the feeding guide on your food's packaging as a starting point, then adjust based on body condition score.
- Weigh your puppy monthly and update portions as they grow — needs change rapidly in the first year.
- Large breed puppies should be kept lean — avoid free-feeding or over-supplementing.
- Body condition score (aim for 4–5 on a 9-point scale) is the most reliable real-world guide to portion size.
