When Is a Maltipoo Full Grown?

As a Maltipoo owner, it can be helpful to understand just how big they will get. Since there are two types of Maltipoos — Toy, and Mini — knowing their height, weight, and maturation age can help owners prepare for their beloved Fido!

How Big Will My Maltipoo Be?

Knowing some size predictions for your Maltipoo is a helpful way to see how big they will grow. Like any other dog breed, owners can predict how big their pup will grow based on certain factors.

The typical thing to remember as a Maltipoo owner is that the smaller the dog is, the sooner it will reach its full size.

Once a Maltipoo has reached its “halfway” point, it will usually slow down in terms of growth. At this point, Maltipoos are typically as tall as they will be by the end of their lifespan, but they can grow in weight and girth as they age.

Since Maltipoo pups are small, owners can expect their beloved Maltipoo to stay Toy or Mini size for their entire life!

How Big Is a Full-Grown Maltipoo?

So, the real question is — how big is a full-grown Maltipoo dog? The answer depends on the type of Maltipoo you have! There are different types of Maltipoo pups — Toy Maltipoos and Mini Maltipoo dogs.

Toy MaltipooMini Maltipoo
Full-Size AgeUp to 11 months-1 year11 months to 1.25 years
Height (shoulders)½ foot to 1 foot 11 inches to 1.25 feet 
Weight5 to 15 pounds15 to 25 pounds 

Mini Maltipoos

Although Mini seems small, a “Mini” Maltipoo is bigger than the Toy Maltipoo! Even though both of these pups are very small and considered small dogs, the Mini Maltipoo can weigh up to 25 pounds.

Toy Maltipoos

If you have a Toy Maltipoo, you can expect your dog to grow up to 1 foot high and weigh 15 pounds on the bigger end. Although this is uncommon for your Toy to get this big, with the average around .75 feet tall and 10 pounds, a heavier weight is possible.

Owners of Toy Maltipoos can expect to have an accurate estimate of their final weight and height by around 4.5 months. At this point, typically around 18 weeks old, owners can predict their Maltipoo’s final weight and height by doubling their pup’s current size. 

Predicting Your Maltipoo’s Weight

Is there any way that you can have an idea of how big your Maltipoo will get? In short, yes — owners can predict the weight and height of their Maltipoo pup by using a few different factors.

Of course, there are baseline measurements for your Maltipoo dog.

Owners can expect their Maltipoo to weigh upwards of 3 pounds when they are 2 months old, depending on their genetic factors and breed of the mom and dad dog. Once a Maltipoo is fully grown, they typically range upwards of 20 pounds, although a Mini can weigh as much as 25 pounds.

The best way to predict how mighty your Maltipoo might be is to figure out the dog breed of the “mom” and “dad” dog to see if there are any extraneous genetic factors that can change the size prediction of your pup.

When Is My Maltipoo Considered an Adult?

So, when is your pup considered an adult? Although you may want your Maltipoo to stay a puppy forever, this is unfortunately impossible! In this case, it can be helpful to know when they are middle-aged or adults so you can see just how big they will get. Usually, a Maltipoo dog is considered to be an adult once they are 1-year old.

How Fast Will My Maltipoo Grow?

Nobody wants their baby to grow up too fast. The same can be said for a Maltipoo pup! In general, an owner can expect their Maltipoo to grow very fast — unfortunately, they can’t stay puppies forever.

So once your Maltipoo is 5-6 years old, the growth will become non-existent. At this point, you can expect your Maltipoo to be an older adult that is done growing.

However, smaller breeds can continually grow as they get older. Compared to bigger dogs, small dogs have a higher likelihood of growing until they get older than five years. In this case, owners can expect their dog to gain weight or girth as they reach the 6-7 year mark.

Compared to large dog breeds, your Maltipoo will probably live longer!

You can rest assured that your Maltipoo dog will be youthful and energetic as they mature, with most small dogs living upwards of 15 years if they have good genetics, diet, and exercise regime.

Check Your Maltipoo for Health

Another must-do maintenance tip for your Maltipoo’s health and happiness is to make sure you check their height and weight. The last thing you want is for your dog to be at the extremely high or extremely low end of the weight and height spectrum. Keeping your Maltipoo healthy and happy ensures your pup will live for as long as possible.

Inspect the Maltipoo

Although you probably look at your dog every single day, you really need to take a step back and look at your dog from a health point of view.

Get a high point of view of your dog to see the girth of your pup — if you find that the waist is too boney or too big, this is cause for concern.

You want your dog to be well-nourished without carrying extra weight. Furthermore, if your pup’s hip bones are showing, this could indicate that your dog is underweight.

Look at the Side

Just like you ended up seeing your Maltipoo from a bird’s eye point of view, look at your beloved dog from the side to see if they are shaped proportionately.

Make sure the ribs and hips are not sticking out of the fur and protruding. Furthermore, ensure the belly is not sticking out too far from the chest level.

You want the belly of your Maltipoo and the chest of your dog to be at the same level, showing a healthy weight and healthy fur without being too big.

Inspect the Curves

Lastly, look at the curves and the bones of your dog. You want to make sure your dog doesn’t have any bones sticking out while also ensuring your dog is not too curvy. If your Maltipoo is barrel-shaped, this is a clear indication your dog is overweight.

If the ribs are too noticeable, this indicates a weight that is dangerously low. A healthy dog should have curves without being too pronounced.

Ensure Your Dog Is at the Right Weight

The last thing you need to know as a Maltipoo owner is how to keep your dog at a healthy weight. This means that you feed your dog enough to keep them well-nourished but also provide your Maltipoo with enough series that they are not too big.

Go on Walks

Going on walks with your dog is not only a good way to bond with your pup, but also a great way to get exercise! If you don’t have time to go on walks during the day when you are at work, try and hire someone who can bring your pup on walks while you are out of the home.

Treats Should Be for a Special Occasion

We know you want to make your dog happy, but treats should only be reserved for special occasions or training your dog to learn new tricks!

Snacks are one of the major reasons why dogs gain weight. Try and avoid giving your pup a treat every day to make them happy. Saving treats can also help you teach your dog discipline and help them with behavioral issues as they get out of their puppy phase.

Avoid Feeding Your Dog Human Food

The third rule of thumb to keep your dog at a healthy weight is to avoid feeding your dog from the dinner table.

Although it can be tempting to give your dog a bite of steak as they are begging under the table, this can lead to bad manners and added fat on your Maltipoo.

Even though some lean meats are okay for your dog to have, try and stick with dog-friendly snacks and dog food to help your dog stay lean and healthy.

Add Supplements

The last bit of advice to keep in mind as a Maltipoo owner is to be aware of having an underweight dog. Keep the same above advice in the back of your mind and add a supplement to ensure your dog is getting the right nutrients in their daily schedule.
