Adult weight by variety

Toy

6–12 lb

Miniature

12–18 lb

Standard / Maxi

19–30 lb

Heights: Toy 9–10 in · Miniature 11–14 in · Standard / Maxi 15–18 in

How confident is this estimate? Based on veterinary consensus; designer breeds vary more than purebreds. As a designer/mixed breed, expect a wider band than for a purebred; two puppies from the same litter can finish at different sizes.

About this breed's data: Variant breakdown follows Daily Paws (Toy 6-12 lb, Mini up to 18 lb, Standard >19 lb). The Standard 30 lb upper cap is an estimate (Daily Paws states only '>19 lb'). PetMD gives a different overall range of 15-22 lb.

How we calculate this

Cockapoo questions

How big do Cockapoos get?

A full-grown Cockapoo's adult weight depends on its variety: about 6–12 lb (Toy), 12–18 lb (Miniature), or 19–30 lb (Standard / Maxi). Because the variant makes such a big difference, use the calculator above with your puppy's current age and weight for a tighter estimate.

When do Cockapoos stop growing?

Most Cockapoos reach their full adult size around 12 months, in line with small-size dogs. They do most of their growing in the first 6 months, then fill out more slowly.

Are these Cockapoo size estimates accurate?

Based on veterinary consensus; designer breeds vary more than purebreds. Estimates are typically within 10–20% for purebreds; designer and mixed breeds vary more. We always show a range and clamp it to this breed's known adult size.
