How big is a Cockapoo full grown?

7 to 30 pounds across every size this breed comes in, standing 15 to 18 inches at the shoulder. No registry recognizes this cross, so these are typical ranges rather than a standard.

How can I tell how big my Cockapoo puppy will get?

Weigh your puppy and enter its age in the calculator on this page. It is already set to the medium growth curve for this breed, so it works backwards from where your puppy is now rather than from the breed average. Four to six months is when the estimate is most reliable.

How often does a Cockapoo need grooming?

A curly or doodle coat needs a groom every 4 to 6 weeks under published guidance. Over a year that adds up, and the grooming cost estimator works out what it comes to for a dog this size.

When does a Cockapoo stop growing?

Weight gain slows to almost nothing at around 10 months for a dog in the medium size class. Height finishes earlier than weight in every breed.

How big does a Cockapoo get?

Typically 15 to 22 pounds at 10 to 18 inches. Which Poodle was used sets where in that band a particular dog lands.

When is a Cockapoo full grown?

A Toy or Miniature is near adult weight at about ten months. A Standard is closer to ten or eleven months and then adds a little.

Less than a Cocker Spaniel, more than a Poodle, and it varies by individual. A low-shedding coat is not a low-maintenance coat: the hair stays in and mats instead, which is why the published grooming cycle for this coat type is four to six weeks.

Cockapoo full grown

A full grown Cockapoo typically weighs 15 to 22 pounds and stands 10 to 18 inches at the shoulder. A Toy Cockapoo from a Toy Poodle stays under 12 pounds, while a Standard Cockapoo from a Standard Poodle goes over 20 pounds and 15 inches.

Fair. Four to five months is the usual time to make this estimate. It is reasonable now, but the range is still wide.

In short

Key takeaways

A full grown Cockapoo weighs 7 to 30 lb across all its sizes.
No kennel club recognizes the Cockapoo, so these are typical ranges built from the parent breeds and a veterinary publisher.
Most of the growing is done by about 10 months.
A curly or doodle coat means regular paid grooming, which is a real yearly cost.
The chart below shows a band, not a line, because individual dogs vary.

Timing

When a Cockapoo stops growing

10 months

before weekly weight gain drops below a quarter of a percent of adult weight

In our figures, a dog in the medium size class has done almost all of its weight gain by about 10 months. After that the weekly gain drops below a quarter of a percent of adult weight, which is slow enough that you will not see it on the scales week to week.

Height finishes earlier than weight. The AKC puts small breeds at full size by 6 to 8 months, medium breeds at around 12 months, and giant breeds at 12 to 18 months, with some very large breeds taking up to 24. In a breed with several sizes, the smaller variety finishes first: that is a size effect, not a breed one.

Variation

Why individual Cockapoos differ

The Cocker Spaniel side is narrow, 20 to 30 pounds, so the Poodle parent decides nearly everything about a Cockapoo's adult size.

The Cockapoo is one of the oldest deliberate Poodle crosses, but it still has no kennel club standard, so the three sizes here are breeder convention rather than an official division.

Cockapoos often inherit the Cocker ear, which is heavy and drops. That is a grooming consideration more than a size one, but it does add to the regular trim.

Running cost

Grooming a Cockapoo

A curly or doodle coat is a running cost, and it is worth knowing the figure before you take a puppy home rather than after. The price per groom goes up with the size of the dog.

How we calculate this

The adult weight and height come from the sources below. The shape of the growth chart comes from our own calculation on the open data behind a published veterinary growth standard, described on the how we calculate page. The charts are estimates built from a breed range and a population curve, not measurements of this breed.
