Maltipoo Weight Chart by Age

Growth Concerns for Maltipoos
Maintain healthy weight
Keeping your Maltipoo lean during growth supports lifelong joint health.
Exercise limits during growth
Growth plates close at approximately 8-10 months. High-impact exercise before this can cause permanent damage.

| Stage | Meals/Day | Food Type | Amount |
|---|---|---|---|
| 8-12 weeks | 3x | Puppy formula | Follow label — 3 meals/day |
| 3-6 months | 2x | Puppy formula | Peak growth — follow label |
| 6-12 months | 2x | Puppy formula | Growth slowing — reduce if gaining too fast |
