When Is A Maltipoo Full Grown?

When Is A Maltipoo Full Grown?

All dogs are adorable but the small ones seem to have that extra something special. Especially when they happen to be a mix of two of the most awesome dog breeds out there, the poodle, and the lovely Maltese. Known for their renowned lovability, Maltipoos are fast becoming one of the most popular of designer breeds.

A beautiful blend of the spunky yet sweet poodle with the unconditional love and loyalty that their Maltese side brings to the proverbial puppy trait table. As beloved as the breed is, it is a fairly new one and as such we are still learning about them. One of the most common questions being asked by Maltipoo parents – what are Maltipoo’s full grown size, weight, and age?

Maltipoo Full Grown Weight 5-20 lb
Maltipoo Full Grown Age Consider adult at around 1-Year-Old

Maltipoo Full Grown Size

  • Due to their unique genetics, there are certain factors that come into play with regards to the full-grown size of the Maltipoo and exactly how much time it takes them to get there.
  • If yours is a first-generation Maltipoo, meaning the parents were a miniature or toy Poodle and a Maltese then you can expect him to be full grown at 8 to 10 months with a size of 8-14 inches tall. A second generation Maltipoo, that is, both mom, and dad are Maltipoos, might not stop growing until he is at least 15 months old.

Predicting Your Maltipoo’s Weight

  • Predicting the weight of any breed is never an exact science, but with the designer breeds, so many factors come into play with regards to the parents. This is why the size of a Maltipoo at any age is going to vary. How big were the parents? Was the Sire (dad) or the Dam (mom) a toy breed? Is he a first or second-generation Maltipoo? Determining an exact weight can be tricky.
  • Generally, you can expect an 8 week old Maltipoo to weigh about 1.5 to 3 pounds, again depending on the size and breed of mom and dad. At fully grown they are typically never more than 20 pounds. This is why it is always a good idea to meet the parents when getting your Maltipoo puppy. This can give you the best idea of how big he will end up being.

When Does A Maltipoo Puppy Turn Into An Adult?

While they may grow quickly, emotionally, and behavioral-wise, a Maltipoo stays puppy-like for most of his life. That is one of the things that make these awesome little dogs so special (and popular). In the technical sense, the puppy stage goes by very fast and your Maltipoo is considered an adult at around a year of age.

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.


Maltipoos come in a variety of colors, and their coats can come in several different textures. Their parentage plays a large role in texture but the most common three types are as follows: soft and silky, wavy and wiry, and thick and curly. As they get older their coloring may change, however, Maltipoos are typically not dark in color due to their Maltese half. The Maltese breed tends to be predominately all white.

How To Check If A Maltipoo Is Too Light Or Too Heavy

Determining whether your pooch is over or underweight is fairly simple, although if your Maltipoo has a thicker coat it could be deceiving.

  • Get a bird’s eye view of Fido. His waist should be defined, but not so much so that his hip bones are protruding.
  • Check him out from the side. The ribs and hips should not be overly prominent, but you should be able to see them. The belly should not be level with the chest nor should it hang below it.
  • Dangerous curves ahead. Does your Maltipoo resemble a barrel or a sausage? This is a clear indicator of being overweight. If his ribs are quite noticeable and the hips protrude, he is likely underweight. A healthy dog should have soft but defined curves. Not too big, not too thin, just right.

Helpful Tips For Maintaining Weight

  • Limit the treats: Yes, it will be hard to resist that cute face and big, soulful brown eyes, but it is very much in his best interest. Snacks are one of the major causes of canine obesity. Moderation is key and if your pup is already on his way to becoming sausage-shaped, it might be a good idea to switch to a lower-calorie treat.
  • Take walks: The positives are abundant: the mental stimulation of your Maltipoo with all of the sights and sounds, it gets him much-needed exercise, and he learns to be socially appropriate (no jumping, pulling, excessively barking, etc.)
  • Two is always better than one: Having a like-minded playmate can help to keep them both in shape. They also keep each other company when you are unable to give your full attention. Be sure to get them spayed or neutered
  • No people food: This is a big one. Absolutely, positively, no people food for your precious pooch. None. It is fattening, his body is not made to digest certain things, and some foods can be highly toxic to canines. There are plenty of healthy, dog-friendly alternatives for Fido’s snacktime.
  • Underweight dogs: If yours is on the other end of the chunky-butt spectrum, you should still heed the above advice. However, adding a nutritional supplement, such as NutriCal, to your underweight dogs’ diet can help him put on some pounds, in a healthy way.

How To Ensure Complete Maltipoo Happiness And Healthfulness

Despite what some may believe, a dog is not simply just a dog, and no two are alike. Each is their own individual with their own individual needs. Personality traits and characteristics vary greatly from breed to breed (and dog to dog), much like their human counterparts. To give your Maltipoo the best possible life, you need to really get to know him. Knowing your dog can help you understand what he needs to be happy and healthy. And of course, annual veterinary check-ups are a must. It is better to catch an illness or injury early and get it treated (and it usually results in a far better outcome).

Dogs have naturally evolved to be man’s perfect companion. And you most certainly would never find a more loyal and loving best friend. Your dog has happily dedicated his life to you and with your Maltipoo, this is even more true. This breed really loves ‘their’ humans. They will not be content outside or locked away all day. They want to be right in the middle of the action, preferably while perched on your lap.

That being said, if you are strictly looking for a designer dog to carry around in your handbag, the Maltipoo might not be for you. While they are generally a tiny breed, the smallness is not a guarantee. Depending on their lineage, a Maltipoo can be anywhere from five to twenty pounds and have a fully grown height of eight to fourteen inches. Their size is not as set in stone as say a teacup dog would be.

Dogs become very attached, fairly quickly, and they can experience depression, so be sure you are ready to commit. If you go for it, it will be one of the best choices you’ll ever make. No matter the size, there is no doubt that your new Maltipoo is sure to be a furball of complete love and devotion. It will be one decision that you will never regret.
