Maltipoo weight chart
A Maltipoo's adult weight varies more than most breed charts allow for, because it is a cross between a Maltese and either a toy or miniature poodle, and which size of poodle sits in the pedigree makes a real difference. Depending on that, an adult Maltipoo might settle anywhere from around 2.5kg up to roughly 9kg.
Why the range is so wide
Maltipoos are not a breed with a fixed standard, so there is no single official weight range the way there is for a recognised pedigree breed. A Maltipoo bred from a toy poodle will typically stay smaller, while one bred from a miniature poodle can end up noticeably larger, and puppies from the same litter can still vary within that.
If you know which size of poodle was used in your Maltipoo's parentage, that is a far better guide to their likely adult size than a single generic figure for the crossbreed as a whole.
How weight tends to build
As a small breed overall, most Maltipoos reach close to their adult weight faster than a large breed would, typically by around eight to twelve months old, though the smallest toy-sized dogs can finish even sooner. Growth in the first few months is usually rapid relative to their small final size.
Because the adult size range is genuinely wide across the crossbreed, tracking your own puppy's steady week-to-week progress matters more than comparing them against a single fixed number that may simply not apply to their particular parentage.
Common questions
- How can I predict how big my Maltipoo puppy will get?
- Knowing whether a toy or miniature poodle was used in the parentage is the most useful guide, since it affects the likely adult size more than almost anything else. Your breeder should be able to tell you this if you do not already know.
- At what age is a Maltipoo fully grown?
- Most Maltipoos reach close to their adult size by around eight to twelve months old, though this can vary depending on which size of poodle is in their background. Toy-sized Maltipoos often finish growing a little earlier than larger ones.
- Is it normal for Maltipoo littermates to be different sizes as adults?
- Yes, because Maltipoos are a crossbreed without a fixed standard, some variation between littermates is normal, particularly if the parentage includes different sizes of poodle further back. This is more common than it would be in a standardised pedigree breed.
