Typical weights by month. Individual puppies often sit 10–15% above or below these numbers. Last reviewed October 7, 2026.
The AKC gives only a maximum weight for this breed, so the chart shows a puppy that grows up to that maximum. Most adults will be a little lighter.
How big does a Maltese get?
According to the American Kennel Club's breed profile for the Maltese, adults weigh: male & female under 7 lb. Life expectancy is 12–15 years.
| Weight | Height | |
|---|---|---|
| Male & female | under 7 lb | 7–9 in |
When does a Maltese stop growing?
Maltese grow like other toy-sized dogs: they are close to adult weight at around 10 months. At 6 months a typical Maltese puppy has reached about 83% of its adult weight.
To estimate your own puppy's adult weight from its current weight and age, use the puppy weight calculator and choose "Toy" as the expected adult size.
How the chart is made
The adult weights come from the AKC breed profile. The weight at each month is estimated with our toy-breed growth curve, which gives the share of adult weight a typical puppy of that size reaches at each age. The curves are simplified from published research on dog growth, including the growth standard charts by Salt and colleagues (PLOS ONE, 2017).
If your puppy is well below or above the chart, stops gaining weight, or looks very thin or round, ask your vet to check its body condition.
