Puppy Weight Chart by Age & Size
Compare broad puppy weight ranges by age and expected adult size, from 8 weeks through 12 months. Use the chart as a reference, not as a one-size-fits-all target.
Puppy Weight Chart
Puppies grow at very different rates. A toy-breed puppy, a Labrador-sized puppy, and a giant-breed puppy can be the same age while weighing very different amounts. That is why a useful puppy weight chart needs to consider expected adult size.
The ranges below are broad educational references. Your puppy’s breed, genetics, parents, sex, nutrition, health and individual growth pattern can place them above or below a general range.
| Age | Toy | Small | Medium | Large | Giant |
|---|---|---|---|---|---|
| 8 weeks | ~2–4 lb | ~4–8 lb | ~8–15 lb | ~15–25 lb | ~20–35 lb |
| 10 weeks | ~2.5–5 lb | ~5–10 lb | ~10–18 lb | ~18–31 lb | ~25–43 lb |
| 12 weeks | ~3–6 lb | ~6–12 lb | ~12–22 lb | ~22–38 lb | ~30–50 lb |
| 16 weeks | ~4–7 lb | ~8–16 lb | ~16–30 lb | ~30–50 lb | ~40–65 lb |
| 20 weeks | ~5–8 lb | ~10–19 lb | ~20–37 lb | ~38–62 lb | ~52–82 lb |
| 6 months | ~5–9 lb | ~12–22 lb | ~25–45 lb | ~45–75 lb | ~65–100 lb |
| 9 months | ~6–10 lb | ~15–24 lb | ~32–48 lb | ~55–85 lb | ~80–120 lb |
| 12 months | ~6–10 lb | ~17–25 lb | ~40–50 lb | ~65–90 lb | ~100–140 lb |

Age is one of the most important pieces of context when looking at puppy weight. The same number on a scale can mean something completely different at 8 weeks, 16 weeks, or 6 months.
8 Week Puppy Weight
Early growth is rapid, and expected adult size makes a major difference.
12 Week Puppy Weight
Growth remains rapid, but breed and adult-size differences become increasingly useful.
16 Week Puppy Weight
Many puppies are well into their growth phase, with size-specific patterns becoming clearer.
20 Week Puppy Weight
Medium, large and giant puppies can still have substantial growth ahead.
6 Month Puppy Weight
Many puppies have reached a substantial portion of adult size, but maturity varies.
12 Month Puppy Weight
Small dogs may be near adult size while larger dogs can still be developing.
How to Use a Puppy Weight Chart Correctly
- Start with exact age. Use weeks when your puppy is young because growth can change quickly.
- Use a recent measured weight. Avoid estimating weight from appearance alone.
- Consider adult size. A chart for a toy puppy should not be compared directly with a giant-breed puppy.
- Look at the trend. Several measurements are more informative than one isolated number.
- Consider breed and parents. Genetics can shift expected adult size substantially.
What Is a Healthy Puppy Weight?
A puppy’s healthy weight cannot be determined from age alone. Two puppies of the same age can have very different healthy weights because they may be different breeds or expected adult sizes.
Body condition is also important. A puppy that falls outside a generic chart range is not automatically underweight or overweight. If you are concerned about your puppy’s growth, a veterinarian can assess body condition and overall development.
Puppy Growth vs. Puppy Weight
A puppy weight chart tells you about weight at different ages. A puppy growth chart focuses more broadly on how puppies progress through their growth stages and how the timing differs between small and large dogs.
If your main question is “How big will my puppy get?”, use the puppy adult-size guide and then use the puppy weight calculator for a personalized estimate.
Why Breed-Specific Puppy Weight Charts Matter
A general puppy weight chart is useful for understanding the overall concept, but breed-specific information can narrow the expected range. A Chihuahua puppy and a Great Dane puppy can both be 12 weeks old while being dramatically different sizes.
Our breed section will progressively add dedicated growth resources so you can compare general puppy weight information with breed-specific expectations without turning every keyword variation into a separate thin page.
When Do Puppies Stop Growing?
Growth does not end at the same age for every dog. Toy and small breeds generally reach adult size earlier, while large and giant breeds often continue growing for longer. Weight maturity and skeletal or muscular maturity can also occur on different timelines.
