How Big Do Cockapoos Get?

Cockapoos come in a wide range of sizes because the Poodle parent can be a toy, miniature, or standard. Most Cockapoos weigh between 12 and 25 pounds and stand 10 to 15 inches tall at the shoulder. The size of the Poodle parent is the biggest factor in determining how large your Cockapoo will grow.

Cockapoo Sizes by Type

Teacup or Toy Cockapoo. Bred from a toy Poodle and a Cocker Spaniel, these are the smallest Cockapoos. They typically weigh under 12 pounds and stand less than 10 inches tall. Teacup Cockapoos are popular for apartment living and for owners who want a truly compact companion. They reach their full size by about 9 to 12 months.

Miniature Cockapoo. This is the most common size and comes from crossing a miniature Poodle with a Cocker Spaniel. Miniature Cockapoos usually weigh 13 to 18 pounds and stand 11 to 14 inches tall. They are the perfect middle ground size, small enough for apartments but sturdy enough for active families.

Standard or Maxi Cockapoo. Bred from a standard Poodle, these are the largest Cockapoos. They can weigh 19 to 30 pounds or more and stand 15 to 18 inches tall. Standard Cockapoos are less common but make great family dogs for people who want a bigger, more robust companion.

When Do Cockapoos Stop Growing?

Most Cockapoos reach their full adult size between 9 and 12 months of age, though larger standard Cockapoos may continue filling out until 14 to 18 months. The height usually reaches its maximum first, followed by the chest and body broadening over the next few months.

Toy and miniature Cockapoos tend to reach their full size faster than standard ones. You can usually get a good idea of your Cockapoo’s adult size by doubling its weight at 4 months old, though this is just a rough estimate.

Predicting Your Cockapoo’s Adult Size

The most reliable way to predict size is to look at the parents. Ask your breeder about the weights of both the Cocker Spaniel and Poodle parents. Your Cockapoo will likely fall somewhere in between, though genetics can be unpredictable with mixed breeds.

Paw size can give you a clue. A puppy with large paws relative to its body usually has more growing to do. Once the paws look proportional, your Cockapoo is likely close to its adult size.

The generation also plays a role. F1B Cockapoos (backcrossed with a Poodle) may be slightly different in size than F1 Cockapoos (50/50 mix). If you have specific size requirements, talk to your breeder about which pairing is most likely to produce the size you want.

Factors That Influence Size

Genetics. The parents’ sizes matter most, but grandparent genetics can also play a role. A Cockapoo from two moderately sized parents could still end up on the larger or smaller end if there are bigger or smaller dogs in the recent family tree.

Nutrition. Proper nutrition during puppyhood supports healthy growth. Overfeeding can cause a puppy to grow too fast, which puts stress on developing joints and bones. Underfeeding can stunt growth. Follow your vet’s feeding guidelines for your puppy’s expected adult size.

Spay or neuter timing. Some research suggests that early spaying or neutering may allow dogs to grow slightly taller because the growth plates stay open longer. The effect is usually minimal, but it is something to consider when planning the timing with your vet.

Keeping Your Cockapoo at a Healthy Weight

Once your Cockapoo reaches its adult size, maintaining a healthy weight is important. Cockapoos can be prone to weight gain, especially if they are not getting enough exercise or are eating too many treats. An overweight dog is at higher risk for joint problems, diabetes, and heart disease.
