Growth Velocity Note

50% of adult weight is reached as early as 12 to 14 weeks. Growth after 7 months is minimal.

Veterinary Feeding Guidance:

Feed frequent, small calorie-dense meals during weeks 8–16 to protect against toy breed hypoglycemia.

When Do Maltipoo Growth Plates Close?

For the Maltipoo (toy breed classification), epiphyseal growth plates typically close between 8–10 months. Until these cartilaginous zones calcify into solid bone, the skeletal structure is particularly vulnerable to impact trauma.

  • Avoid repetitive high-impact jumping (such as off tall beds or out of SUVs).
  • Postpone intense agility hurdles or forced running on concrete until growth plate fusion is complete.
  • Maintain lean body condition: excess puppy fat places unnecessary biomechanical torque on immature ligaments.

Nutrition & Weight Maintenance

Caloric demand peaks between 8 and 16 weeks, during which puppies require up to twice the calories per pound of body weight compared to adult dogs.

Feed frequent, small calorie-dense meals during weeks 8–16 to protect against toy breed hypoglycemia. Weigh your puppy bi-weekly and adjust portions according to their body condition score (BCS) rather than bag recommendations alone.
