How Big Do Maltipoos Get?

“How big will she get” is the first thing new maltipoo owners ask me, and most of that answer was settled before the puppy was born. A maltipoo is a Maltese crossed with a poodle. The Maltese barely varies, always a small white dog, so the poodle side is what moves the number. And the poodles used for this cross come in two sizes.

So before you try to read the future off the puppy in your lap, find out which poodle was in the mix. That one fact beats the puppy’s current weight every time.

There’s no standard or “maxi” maltipoo the way there is with a cockapoo, because breeders skip the big standard poodle for this cross. If nobody can tell you the parent, bet on the smaller end. Most pet maltipoos trace back to a toy or a small miniature poodle, which is why so many settle into that 6-to-10-pound pocket.

How small do they start?

Smaller than you’re picturing. An eight-week-old maltipoo is often under two pounds, a handful of fluff you can cup in both palms. I tell every foster family the same thing: go meet the puppy in person before you commit. The little thing on the blanket and the dog in that chart above are hard to believe are the same animal.

Growth chart by age

Here’s the rough curve for a maltipoo headed toward the 6-to-10-pound range. Read it as a guide, not a promise. Every pup runs a little ahead or behind, and the smaller the dog, the more a few ounces swings the percentage.

A maltipoo from two toy parents tracks the low end of every row. One from a bigger miniature poodle rides the top. The shape holds either way: quick early growth, then a long slow fill as the dog packs on body rather than height.

When is my maltipoo full grown?

Height first, weight second. Most maltipoos reach close to their adult height by seven or eight months, then spend the next few months thickening through the chest and legs. Call it finished around a year. Small dogs wrap up growth earlier than big breeds, so don’t wait for a growth spurt that isn’t coming.

How can I predict the adult size?

Three checks, in the order I trust them. First, the parents’ weights, since your puppy almost always lands between the two. Ask the breeder, and ask to see both dogs if you can. Second, a small-breed rule of thumb: the weight at six months is close to the adult weight. Third, the old big-paws test, loose skin and oversized feet meaning there’s growing left. The parents beat the paws, always.

Is a teacup maltipoo real?

No. Not as a real type, anyway. “Teacup” is a sales word, not a size class any registry recognizes. What a breeder usually means by it is a maltipoo bred to stay under about four pounds, often by pairing the two smallest, sometimes runtiest, dogs they’ve got.

I steer people away from them. A dog that small comes with real trouble baked in: fragile bones that snap from a jump off the couch, blood-sugar crashes, teeth crammed into a mouth the size of a thumbnail, and a heart and windpipe that were never built to run that tiny. You pay a premium for the word “teacup” and often get a more delicate dog for it. A healthy five- or six-pound maltipoo is already a lap dog. There’s nothing to gain by chasing smaller.

Is my maltipoo overweight, or just fluffy?

You honestly can’t tell by looking at this breed, because the coat lies. Use your hands. Run them down the dog’s sides. You want to feel the ribs under a thin layer, about like the back of your hand. From above there should be a waist tucking in behind the ribs. That coat hides a chunky dog and a skinny one equally well, which is one more reason to keep it brushed down to the skin, covered in the maltipoo grooming guide. And on a dog this small, half a pound of extra weight is a real slice of the body, and it lands straight on those tiny knees, the exact joint maltipoos already tend to have trouble with.

For the whole breed at a glance, start with the maltipoo breed guide. A growing puppy is a training puppy, so run this next to the maltipoo training guide for the housebreaking and calm alone-time that fill those first months. Want something a notch bigger? The cockapoo runs a bit heavier, and the rest of the designer crosses cover every size from pocket dog to couch-filler.
