How this was calculated
For a Maltese we use the toy-breed growth curve (matures around 11 months): adult weight ≈ current weight ÷ the fraction of adult weight a toy breed reaches at this age. Typical adult weight (4–7 lb) is from the AKC breed standard. The gauge shows where your prediction lands against the breed-typical adult range.

| 3 months | 3 lb (1.4 kg) |
| 4 months | 3.7 lb (1.7 kg) |
| 5 months | 4.2 lb (1.9 kg) |
| 6 months | 4.7 lb (2.1 kg) |
| 7 months | 5 lb (2.3 kg) |
| 8 months | 5.3 lb (2.4 kg) |

Maltese growth, explained
Malteses are a toy breed, so they follow the toy-breed growth curve. AKC standard: under 7 lb. A tiny toy breed — light-boned, so a pound or two of extra weight shows quickly. Most reach close to their adult weight by around 11 months, then continue to firm up in muscle and chest for a while after.
To predict an adult weight we divide your puppy’s current weight by the fraction of adult weight a toy breed has typically reached at that age. Typical adult weight (4–7 lb) is from the AKC breed standard. The result is an estimate with a likely range — genetics and nutrition move individual dogs up or down. If your Maltese looks heavier or lighter than the breed-typical band, your vet is the best person to check.
Maltese weight questions
- How big do Malteses get?
- A typical adult Maltese weighs about 4–7 lb. AKC standard: under 7 lb. A tiny toy breed — light-boned, so a pound or two of extra weight shows quickly.
- What should a Maltese weigh by age?
- See the Maltese growth chart above for weight at 8 weeks through to adult. As a guide, a toy-breed puppy is roughly half its adult weight by about 4 months.
- Do male and female Malteses weigh differently?
- Males average slightly heavier than females, but the Maltese standard gives a single 4–7 lb range rather than a split, so the chart shows one typical curve.
- When is a Maltese fully grown?
- Malteses are a toy breed and usually finish growing around 11 months, though they may keep filling out a little after that.

- Within about 10–15% if your puppy is a typical Maltese. Crossbreeds, runts and big-boned individuals vary more. It’s an estimate — your vet can assess your individual dog.
