When Does a Maltipoo Stop Growing?

Pet Care


August 12, 2022

There are more and more pet owners who are opting for breeds like the Maltipoo. These dogs are manageable in size, but it helps to know just how big they can get. What do they look like when they are full grown?

A mix of the Maltese and Poodle, they are a small breed of dog. But they can range quite a bit in size, from 5 to 25 pounds and 6 to 14 inches in height. That is a pretty broad estimate.

When Do Maltipoos Stop Growing?

Trying to estimate when a Maltipoo will stop growing can be relatively easy. But the first factor is knowing what kind of poodle that the Maltese was bred with.

For those bred with toy poodles, the puppy will be on the smaller side. That means they will be done growing far sooner than any other larger dog will be. It is not uncommon for smaller maltipoos to reach their full size between the ages of 6 and 9 months.

Standard poodle mixes can keep growing past one year of age, though most will stop right around the 9-month mark. A good indicator is how large its parents were. Larger breeds naturally take longer to hit their growth size while smaller breeds will reach it more quickly.

Because of those variances, it can be hard to predict how big a Maltipoo will be when they stop growing. The smallest can be about 6 inches tall and 5 pounds in weight. Others can be 14 inches in height and weigh up to 25 pounds.

Maltipoo Weight Chart

There are generally two Maltipoos that you will run across: toy and mini. Knowing the different weights can be helpful so you know just how big a dog you are dealing with. It will also help you know “when does a Maltipoo stop growing?”

Toy Maltipoo. When you look at a toy Maltipoo, follow the age in weeks; there will be an average weight for what they are supposed to be. The toy Maltipoo will stop growing before they hit their first year. They will generally top out at no more than 10 pounds, though they can grow to be as big as 11 inches in height.

Mini Maltipoo. The mini Maltipoo, despite its name, is actually the larger of the two breeds. A maltipoo that weighs roughly 5.5 pounds at the four-month mark can get to be around 12 pounds by the time they reach their first year.

The average weight of an adult mini Maltipoo will be somewhere between 12 and 15 pounds. Additionally, they will stand anywhere from 11 to 14 inches. It makes them smaller dogs, but they are still bigger than the toy and teacup Maltipoo options.


There is the question as to whether neutering or spaying your dog will have an impact on their growth. The spaying and neutering procedures are surgically done, removing reproductive organs on either males or females respectively.

If the procedure is done too early, it can have an impact on the growth plates of your Maltipoo. They will not have closed properly, which can keep them from achieving their full growth by the time they hit the end of their first year.

Spaying and neutering do have certain health and behavioral benefits, however. It reduces their aggressiveness, prevents pregnancies and breeding, marking of territories, and even minimizing testicular, mammary, and ovarian cancer potential.

How to Weigh and Measure Your Maltipoo?

You may be so inclined to weigh and measure your Maltipoo from time to time. It is a great way to monitor their weight, ensuring that they maintain a healthy weight for the duration of their lives. Make sure that you weigh them every six months or so, using your bathroom scale at home.

Just make sure that it is on a flat surface and record the weight of you standing alone and then you holding the Maltipoo. Subtract the difference and you have the weight of your Maltipoo. There are also dog scales out there but make sure that they start out young to get them used to sitting on the scale.

Because of the difficulty that can be involved in weighing your Maltipoo, you may be better off waiting until they go to the vet. Vets not only have the right scale, but they know how to keep small dogs in place long enough to get a reading.

They can also give you a better idea as to whether or not your Maltipoo is the right weight or whether there is underfeeding or overfeeding happening. It can be difficult to get their diet just right given their naturally small size but a vet can be helpful in determining their diet.


It can be hard to determine when your Maltipoo will stop growing because there are different breed variations. The ranges can be pretty exponential, but you can get a good idea of their final weight and height by around the nine-month mark.

Each type has its own developmental path, but you can start to see their incremental growth quickly. The deciding factors have to do mainly with their genetics, and you can see how big they will be based on their parents.
