Maltese weight chart
A fully grown Maltese is a toy breed and typically settles at a small adult weight, generally within a few kilograms once mature. A weight chart is a useful general guide to whether a puppy's growth is roughly on track, but it's a guide rather than a rulebook — individual puppies within the breed vary, and your vet is the best judge of whether your own dog's weight is healthy.
How to read a weight chart sensibly
A breed weight chart plots an average growth curve based on typical puppies of that breed, which means any individual puppy can sit comfortably above or below the line without it meaning anything is wrong. What matters more than hitting an exact figure at an exact age is a steady, consistent growth pattern without sudden jumps or unexplained drops.
Because Maltese are such a small breed, even a modest change in kilograms represents a much bigger proportional shift in their body weight than the same change would for a larger dog. This is part of why regular weighing, ideally at the same time and using the same scale, gives a more useful picture than a single reading compared against a chart.
What affects a Maltese's adult weight
Genetics play the biggest role in where an individual Maltese settles as an adult, with some lines running slightly larger or smaller than the breed average. Diet and activity level matter too, particularly around avoiding excess weight gain, since even a small amount of extra weight is proportionally significant on such a small frame.
If your Maltese's weight seems to be tracking well outside what feels like a normal range for their age, or you're at all unsure whether their current weight is healthy, a vet check gives a far more reliable answer than comparing against a general chart alone.
Common questions
- What is a healthy adult weight for a Maltese?
- Maltese are a toy breed and typically settle at a small adult weight of only a few kilograms, though this varies between individual dogs. A vet can assess your specific dog's body condition, which is a more reliable measure of a healthy weight than a number on a chart alone.
- Why does my Maltese puppy weigh differently to the chart?
- A weight chart shows an average growth curve, and individual puppies commonly sit above or below it without anything being wrong. A steady, consistent growth pattern matters more than matching an exact figure at an exact age.
- How often should I weigh a Maltese puppy?
- Weighing every couple of weeks during the growth period, at the same time of day and on the same scale where possible, gives a more useful trend than a single one-off weighing compared against a general chart.
- When should I be concerned about my Maltese's weight?
- A sudden weight change, a puppy who seems to have stopped growing steadily, or ongoing uncertainty about whether their weight is healthy are all good reasons to check with your vet rather than relying on a chart alone.
