A Maltipoo’s adult size comes down almost entirely to one thing: whether the Poodle parent was a Toy or a Miniature. Toy-line Maltipoos usually finish around 5 to 10 pounds; Miniature-line Maltipoos usually finish around 10 to 20 pounds.
That is a two-fold difference, and it is the single most useful question you can ask before you fall in love with a puppy. Everything else on this page is detail around that one fact.
Why the Poodle parent decides it
The Maltese side barely varies. The breed standard for the Maltese calls for a dog under 7 pounds, with 4 to 6 pounds preferred. So whichever Maltese is involved, that parent is small.
The Poodle side varies enormously:
- Toy Poodle: 10 inches or under at the shoulder, per the breed standard.
- Miniature Poodle: over 10 inches and up to 15 inches at the shoulder.
A Miniature Poodle can be half again as tall as a Toy. Cross either one with the same 5-pound Maltese and you get two very different dogs. That is why we list the Poodle variety when we know it, and why we tell you plainly when we do not.
Expected adult weight and height
Toy Poodle line
- Weight: about 5 to 10 pounds
- Height: about 8 to 10 inches
Miniature Poodle line
- Weight: about 10 to 20 pounds
- Height: about 10 to 14 inches
These ranges overlap at the edges, and individual dogs land outside them. A mix is not a standardized breed — there is no official Maltipoo standard anywhere, because no kennel club recognizes the cross as a breed. That means no breed body has defined what size a Maltipoo should be, and nobody can guarantee an adult weight.
Why there is no weight-by-age chart here
Nothing credible publishes age-by-age weights for a crossbreed. No registry recognises this cross, no breed club tracks it, and the two parent standards describe adult dogs rather than puppies. Any chart claiming to know what one weighs at fourteen weeks was invented by somebody. What we can give you is the adult bracket above, drawn from the parent standards, and the growth timeline below.
What affects adult size
The Poodle variety. Covered above. Nothing else on this list comes close.
The actual parents, not just the labels. A small Miniature Poodle at 11 inches and a large one at 15 inches produce noticeably different puppies. Ask for both parents’ adult weights, not just Toy or Mini.
Generation. A first-generation Maltipoo is one Maltese crossed with one Poodle. Later generations — Maltipoo bred back to a Poodle, or Maltipoo to Maltipoo — shift the odds depending on which Poodle variety is involved. Generation labels shift probabilities; they do not set outcomes.
Mixes simply vary more. Two puppies from the same litter can finish several pounds apart. This is normal for a cross and not a sign that anything went wrong.
Body condition. A heavier Maltipoo is often just a Maltipoo carrying extra weight. In good body condition you can feel the ribs easily under a thin covering, see a waist from above, and see a tuck-up from the side. The coat hides all of this, which is exactly why you have to use your hands.
When they stop growing
Small dogs finish early. Most Toy-line Maltipoos are at or near adult size by 9 to 12 months. Miniature-line dogs often take a bit longer, filling out through 12 months and occasionally a little past it.
Height generally finishes before weight. A dog that has stopped getting taller but is still gaining is usually filling out, not still growing — and past a certain point that is weight gain rather than growth. Your vet can tell you which one you are looking at.
Signs of healthy growth, and when to ask a vet
Look for consistent gradual gains, good energy, steady appetite, and a body you can read by feel. Weigh at the same time of day, on the same scale, about once a week early on.
Call your veterinarian if you see weight loss, a stall in gains in a young puppy, sudden weakness or lethargy, refusal to eat, wobbliness or trembling — small-breed puppies have limited energy reserves and veterinary sources treat low blood sugar as a real risk in young toy-size dogs. Frequent meals and keeping the puppy warm are the standard preventive advice, and anything beyond that is a vet call, not a wait-and-see.
Every puppy in our showroom gets a complete health check from our on-staff veterinarian and is up to date on shots. After that, your own vet is the right person for growth questions.
About the word “teacup”
You will see teacup Maltipoo everywhere. We do not use it. It is not a recognized size — no breed club defines it, and veterinarians treat it as a marketing term rather than a category. Two sellers can use it for dogs that differ by several pounds.
What we give you instead: the Poodle variety when we know it, both parents’ weights when we have them, the puppy’s current weight, and an honest estimate with an honest range. We would rather tell you probably 6 to 9 pounds and be right than promise you 4 pounds and be wrong.
Coat and grooming
One size note that surprises people: a Maltipoo’s soft wavy coat makes the dog look considerably larger than it weighs, and it needs regular brushing and trimming to stay comfortable. We offer grooming if you would rather hand that off. We do not describe any dog as hypoallergenic — coat type varies in this cross, and so does how any individual person reacts.
Frequently asked questions
How do I tell whether my Maltipoo came from a Toy or a Miniature Poodle?
Ask. The breeder or seller should be able to tell you the Poodle parent’s variety and adult weight. When we know it, we tell you. If nobody can answer, treat the adult-size estimate as genuinely uncertain across the full 5-to-20-pound range.
Can two puppies from the same litter end up different sizes?
Yes, and it is common in crossbreeds. Several pounds apart at maturity is normal for littermates.
Is there an official Maltipoo size standard?
No. No major kennel club recognizes the Maltipoo as a breed, so there is no official standard defining its size. Every range you see, including ours, is observed data rather than a rule.
My Maltipoo is bigger than the chart. Is something wrong?
Probably not. Charts are averages of a very variable cross. Talk to your vet about whether your dog’s body condition is appropriate for its frame — that is a more useful question than whether the number matches a table.
Do Maltipoos keep growing after a year?
Most are done by around 12 months, Miniature-line dogs occasionally a little later. Gains well past that point are usually weight rather than growth, and worth mentioning at your next vet visit.
