Maltipoo Growth Chart — Weight by Age & Size Guide

Updated April 202610 min readVet-reviewed sources

How much should your Maltipoo weigh at each age? When do they stop growing? This guide covers month-by-month weight ranges for both male and female Maltipoos, growth milestones, when growth plates close (and why that matters for exercise), feeding guidelines by stage, and the warning signs that something might be off — all backed by veterinary research including population-level data from over 6 million dogs.

Maltipoo Weight Chart by Age

Weight ranges shown are for healthy Maltipoos at ideal body condition. Your puppy should fall within these ranges — being slightly below the range is better than above for long-term joint health.

Growth Concerns for Maltipoos

Maintain healthy weight

Keeping your Maltipoo lean during growth supports lifelong joint health.

Weigh monthly and compare to the growth chart. Feel ribs with light pressure.

Exercise limits during growth

Growth plates close at approximately 8-10 months. High-impact exercise before this can cause permanent damage.

Short walks. Avoid jumping from heights — fragile bones.

Exercise Guide by Growth Stage

0-3 months
Supervised free play

Short sessions on soft surfaces.

3-6 months
5 min per month of age

Structured walks. Free play in yard is fine.

6-12 months
Moderate walks, swimming

30-45 min walks. Gradually increase.

Growth plates closed. All activities safe.

When to Worry — Growth Red Flags

Not gaining weight for 2+ weeks

Could indicate parasites or illness. Vet check recommended.

Gaining too fast

Reduce food by 10%. Excess weight stresses joints.

Limping or reluctance to play

Could indicate injury or joint issues. Vet exam needed.

Distended belly despite thin body

Classic sign of intestinal parasites. Vet visit for deworming.

Frequently Asked Questions

Maltipoos reach adult height by 6-8 months and full weight by 8-10 months. Males typically reach 5-15 lbs, females 4-13 lbs.

Males typically reach 5-15 lbs; females 4-13 lbs. Genetics, nutrition, and neuter status affect final size.

Compare to the chart above. You should feel ribs with light pressure (BCS 4-5/9). If you can't feel ribs, reduce food by 10%.

A puppy formula. Feed 3 meals/day until 6 months, then 2. Switch to adult food at 9-10 months.

After growth plates close — approximately 8-10 months. Before this, use the 5-min-per-month rule for walks.

Early spay/neuter delays growth plate closure, resulting in slightly taller dogs. Neutered dogs have higher obesity risk — monitor food.

Lean is ideal during growth (BCS 4/9). The Purina LifeSpan Study proved lean dogs live 1.8 years longer.

Growing Maltipoos face real health risks

Health conditions that develop during growth can be expensive to treat. Pet insurance covers hereditary and congenital conditions when diagnosed after enrollment.
