How Big Will a Maltipoo Get? Maltipoo Size and Weight Guide

Maltipoos are the adorable mix between a Poodle and a Maltese. These little dogs are ideal for families, with their affectionate nature ideal for the elderly and children alike. But how big will the Maltipoo get? Is their size and weight ideal for your household?

What Size is a Maltipoo?

Although the Maltese only comes in one size, there are multiple sizes of Poodle. This means that the Maltipoo comes in several sizes, usually Toy and Mini. You can expect these to be roughly 5 to 25 pounds (2.3 kg to 11.3 kg) and stand 6 to 14 inches (15.2 to 35.6 cm) tall at the shoulder.

So, let’s look into the size and weight of the adult Maltipoo in more detail so that you know what you can expect before getting your own Maltipoo. In doing this, hopefully, you can figure out not only if the Maltipoo is suitable for you but also just how big your existing Maltipoo might become.

It’s important to remember that the Maltipoo is desirable because it is so small. Because of this, larger Poodles are not used for breeding often. In some cases, teacup Maltipoos can also be formed, but this is only in later generations. 

Maltipoos are not an official breed, so there are no clear guidelines for size, but because Toy and Mini Maltipoos are the most common, we will be considering only those for the purpose of this article. 

Maltipoo Size and Weight Table

MaltipooHeight (at the shoulder)Weight
Toy6 to 11 inches (15.2 to 27.9 cm) 5 to 15 pounds (2.3 to 6.8 kg)
Mini/Miniature11 to 14 inches (27.9 to 35.6 cm)15 to 25 pounds (6.8 to 11.3 kg)

Keep in mind that there will be some variation from the above numbers depending on a variety of different factors. But this is a good estimate to work off of when considering a Maltipoo size and weight.

Toy Maltipoo

The Toy Maltipoo is created by crossing a Toy Poodle with a Maltese. Sizes vary depending on the exact size and genetic background of the Toy Poodle that has been used. But, generally speaking, you can expect a Toy Maltipoo to be around 6 to 11 inches (15.2 to 27.9 cm) tall at the shoulder and 5 to 15 pounds (2.3 to 6.8 kg) as a healthy adult. 

Toy Maltipoos are one of the smallest Maltipoos that you can get. Their tiny size makes them ideal for those who live in small apartments. The Toy Maltipoo also makes a particularly great lap dog.

If you want something very small and easy to control, then this is the best Maltipoo option for you. Keep in mind that if you want a companion that will follow you around outdoors or act as a companion dog for someone quite active, this is probably not the most suitable option. 

Mini Maltipoo

The Miniature, or Mini, Maltipoo, is created by crossing a Maltese with a Miniature Poodle. This results in a Maltipoo that is a little bit bigger than the Toy Maltipoo. However, it is still very much a small dog. 

You can expect your Mini Maltipoo to be roughly 11 to 14 inches (27.9 to 35.6 cm) tall at the shoulder and 15 to 25 pounds (6.8 to 11.3 kg).

Because this is still such a small dog, it is still great if you live in a small space or don’t always have access to a garden. Just keep in mind that even though the Mini Maltipoo is little, it is still a Poodle-hybrid. This means that it will still need a fair amount of exercise. 

If you are a fairly busy family or have a child and want something small that should be able to keep up with you, this is a better option than a Toy Maltipoo.

Does Generation Affect Maltipoo Size and Weight?

Generation does affect the size and weight of a Maltipoo. The Poodle comes in a variety of different sizes. Backcrossing with a Poodle can change the overall size and weight of the puppies.

F1b Maltipoo 

If the Poodles that are used in breeding are smaller than the Maltipoo, such as a particularly small toy Poodle, you will get smaller puppies. If a larger Poodle is used, the puppies will be larger. 

F1bb Maltipoo

Just like when backcrossing once, the size of the Poodle can greatly affect the outcome of a Maltipoo that has been backcrossed twice. 

Some people mention Teacup Maltipoos. These are quite difficult to create because you need to use an unusually small Poodle when backcrossing. They only appear reliably when backcrossing happens several times. 

Alternatively, double-backcrossing can be used to create a rather large Maltipoo. 

When choosing a specific generation for its size, keep in mind that you need to consider the health implications of being 82.5% Poodle. The small difference in size is often not worth the increased susceptibility to certain health issues.

Weight of Your Maltipoo Puppy

There are two points in your Maltipoo’s growth where you should be able to estimate more or less what they will weigh when they are fully grown. 

The first is when your Maltipoo is approximately eight weeks old. This is useful as most people get their puppies at this age. If your Maltipoo puppy weighs less than 2.5 pounds (or 1.1 kg), then you can figure out its adult size by multiplying its weight by four and adding an additional 0.25 pounds (or 0.1 kg) to that final weight.

If your Maltipoo weighs more than 2.5 pounds (or 1.1 kg) at this point, do the same, but add a full pound (or 0.45 kg) at the end. 

If you are adopting a slightly older puppy, you can estimate its final weight at about 4 months again. At this age, they should be more or less half of their adult body weight. 

If you are adopting an even older Maltipoo, they should be very close to their final body weight no later than a year. Smaller Maltipoos are practically fully grown by around ten months!

This is a very useful trick to make sure that you only ever choose the Maltipoo that will suit your family and living situation the best.
