Growth by age and size
Puppy Growth Chart
How much of its adult weight a puppy usually has at each age, for toy, small, medium, large and giant dogs. Use it to see where your puppy is now, or let the calculator do the maths.
Percent of adult weight by age
- Toy
- Small
- Medium
- Large
- Giant
Middle (typical) curve for each size, 8 weeks to 2 years. Adult weight = weight at about 2 years. Sources: Salt et al. 2017 (toy to large), NRC 2006 and Hawthorne et al. 2004 (giant).

How to use it: divide your puppy’s weight by the percentage for its age and size. A 16-week small puppy weighing 9 lb: 9 ÷ 0.46 ≈ 20 lb as an adult. The bracketed range shows how much healthy puppies differ. The calculator does this for any age, not just the rows above.
When do puppies stop growing?
| Size | 50% | 75% | 90% | Growth usually finishes |
|---|---|---|---|---|
| Toy | 17 weeks | 8 months | 14 months | 9–12 months |
| Small | 18 weeks | 7 months | 13 months | 9–12 months |
| Medium | 19 weeks | 7 months | 10 months | 12–15 months |
| Large | 19 weeks | 7 months | 10 months | 15–18 months |
| Giant | 5 months | 8 months | 12 months | 18–24 months |
Toy and small dogs race to about three quarters of their adult weight by 6–8 months, then add the last bit slowly. In the vet-clinic data behind these curves they keep gaining a little in their second year, so their 90% mark comes later than you might expect. Most of that late gain is filling out, not getting taller. Large dogs grow fast for longer and then level off. The “growth usually finishes” column is the common vet guidance (AKC, PetMD).

Giant puppy weight chart (over 88 lb / over 40 kg as adults)
Typical breeds: Great Dane, Mastiff, Rottweiler, Saint Bernard, Newfoundland. Growth usually finishes at about 18–24 months. There is no published growth standard for giant dogs (Salt et al. could not build one because giant breeds grow so differently), so this curve averages the NRC growth table and the timing reported by Hawthorne et al. Treat it as rougher than the others.
