Typical weights by month. Individual puppies often sit 10–15% above or below these numbers. Last reviewed October 7, 2026.
The club gives no upper weight for Standard Cockapoos (over 20 lb), so the chart covers Toy and Miniature sizes. For a Standard, use the puppy weight calculator with the expected adult size.
How big does a Cockapoo get?
According to the American Cockapoo Club, adults weigh: toy under 12 lb; miniature 12–20 lb; standard over 20 lb. PetMD gives a life expectancy of 12–15 years; the club itself says 14–18 years.

| Standard | over 20 lb | 15 in or more |
When does a Cockapoo stop growing?
How fast a Cockapoo matures depends on its size, because smaller dogs finish growing sooner. Typical ages for reaching close to adult weight: Toy at around 10 months and Miniature at around 11 months.
To estimate your own puppy's adult weight from its current weight and age, use the puppy weight calculator.
How the chart is made
The adult weights come from the American Cockapoo Club's size guide. The weight at each month is estimated with our size-class growth curves (a separate curve for each size), which gives the share of adult weight a typical puppy of that size reaches at each age. The curves are simplified from published research on dog growth, including the growth standard charts by Salt and colleagues (PLOS ONE, 2017).
If your puppy is well below or above the chart, stops gaining weight, or looks very thin or round, ask your vet to check its body condition.
