Cockapoo Puppy Weight Calculator & Growth Chart
A popular companion cross between a Cocker Spaniel and a Poodle. Cockapoos vary in size depending on whether a Toy or Miniature Poodle parent was used.

Cockapoo Pediatric Growth Trajectory
Biological sigmoid curve showing healthy weight progression by age (weeks).
Shaded area represents healthy ±1 standard deviation AKC breed corridor.
Growth Velocity Note
Steady juvenile growth up to 18 weeks. Most Cockapoos achieve ~50% of adult weight by 14 to 16 weeks.
Veterinary Feeding Guidance:
Select a quality small-to-medium puppy food to support active energy needs while maintaining a lean body condition score.
Cockapoo Week-by-Week Weight Milestones
Reference data for healthy Cockapoo puppies based on veterinary pediatric percentiles.
| Puppy Age | Expected Weight (lbs) | Expected Weight (kg) | Developmental Milestone |
|---|---|---|---|
| 8 Weeks (2 mo) | 3–6 lbs | 1.4–2.7 kg | Early juvenile transition |
| 12 Weeks (3 mo) | 6–10 lbs | 2.7–4.5 kg | Rapid bone elongation |
| 16 Weeks (4 mo) | 9–15 lbs | 4.1–6.8 kg | ~50-60% adult weight |
| 24 Weeks (6 mo) | 12–19 lbs | 5.4–8.6 kg | Frame height stabilizes |
| 36 Weeks (8 mo) | 13–22 lbs | 5.9–10.0 kg | Chest and muscle consolidation |
| 52 Weeks (12 mo) | 14–24 lbs | 6.4–10.9 kg | Full mature adult weight |
When Do Cockapoo Growth Plates Close?
For the Cockapoo (small breed classification), epiphyseal growth plates typically close between 9–11 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.
Select a quality small-to-medium puppy food to support active energy needs while maintaining a lean body condition score. Weigh your puppy bi-weekly and adjust portions according to their body condition score (BCS) rather than bag recommendations alone.
