Maltipoo Growth & Size Guide: How Big Do Maltipoos Get?
If you're considering adding a Maltipoo to your family—or already have one—understanding their size, growth, and development is key. Whether you're looking for a snuggly Teacup companion or a sturdy Mini Maltipoo, this complete guide covers everything you need to know about how big Maltipoos get, what affects their growth, and how to keep them on a healthy track.
What Is a Maltipoo?
A Maltipoo is an adorable hybrid dog—a mix between a Maltese and either a Toy or Miniature Poodle. Known for their soft, often curly coats and affectionate personalities, Maltipoos are a favorite among families, allergy sufferers, and first-time dog owners.

Full-Grown Maltipoo Size Breakdown
The size of a full-grown Maltipoo depends on which size of Poodle was used in breeding (Toy, Miniature, or Standard), though most commonly, they fall into two categories:
Toy Maltipoo:
Height: 6–10 inches
Weight: 5–10 pounds
Mini Maltipoo:
Height: 10–14 inches
Weight: 10–25 pounds
🐾 Fun Fact: Some breeders also use the term "Teacup Maltipoo" for pups under 5 pounds, though this isn't a recognized category and often comes with health risks.

What Affects a Maltipoo's Growth?
1. Genetics
Puppies inherit traits from both parents. If the Poodle parent was on the smaller or larger side of the spectrum, your puppy may reflect that.
2. Diet & Nutrition
Feeding high-quality, puppy-formulated food ensures healthy growth. Low-protein or low-calorie diets can stunt development.
3. Parasites
Worms and other parasites can prevent proper nutrient absorption, leading to underweight pups.
4. Health Conditions
Issues like pituitary dwarfism, liver shunts, or thyroid dysfunctions can impact development. Always consult a vet if you're concerned.
5. Social Factors
In multi-pet households, timid or bullied puppies might not eat as much or play as confidently, affecting weight gain.
What If My Maltipoo Isn't Growing?
Don't panic—but do consult your vet. Look out for:
Lethargy or low energy
Vomiting or diarrhea
Lack of appetite
Sudden weight loss
Even if your pup seems healthy, an exam and possibly a fecal or blood test can catch hidden issues early.
When Do Maltipoos Stop Growing?
Most Maltipoos reach full height and weight by 10–12 months, with the majority of their growth occurring in the first 6 months.
🐶 Tip: Smaller Maltipoos tend to mature faster than their Mini counterparts.
