As a prospective or current Cockapoo owner, it’s essential to understand their growth patterns and when they reach their full size. In this article, we will explore the different sizes of Cockapoos and provide insights into when they typically stop growing. By gaining this knowledge, you will be better equipped to care for your Cockapoo and ensure their optimal health and happiness.

Understanding Cockapoo Sizes

Cockapoos come in various sizes, ranging from toy to standard, depending on the size of their parent breeds. These different sizes are often classified as Toy Cockapoos, Miniature Cockapoos, and Standard Cockapoos. Let’s delve into each size category:

  • Toy Cockapoos: This is the smallest size category, usually weighing between 6 to 12 pounds (2.7 to 5.4 kg). They stand approximately 9 to 10 inches (22 to 25 cm) tall at the shoulder. Toy Cockapoos are perfect for individuals living in apartments or those seeking a compact, portable companion.
  • Miniature Cockapoos: Slightly larger than Toy Cockapoos, Miniature Cockapoos typically weigh between 13 to 18 pounds (5.9 to 8.2 kg) and stand around 11 to 14 inches (28 to 35 cm) tall at the shoulder. They strike a balance between being compact and providing a bit more robustness.
  • Standard Cockapoos: The largest size category, Standard Cockapoos weigh between 19 to 30 pounds (8.6 to 13.6 kg) and stand around 15 to 18 inches (38 to 46 cm) tall at the shoulder. They offer a more substantial presence and are well-suited for families or individuals looking for a slightly larger companion.

When Do Cockapoos Stop Growing?

The growth rate and final size of a Cockapoo can vary depending on several factors, including genetics, diet, exercise, and overall health. However, as a general guideline, most Cockapoos reach their full adult size by the age of one year to 18 months. It’s important to note that the growth rate may slow down considerably after the initial six months, but some incremental growth may still occur until they reach their final size.

Toy Cockapoos tend to reach their full size earlier, typically around nine to twelve months of age. Miniature Cockapoos may take slightly longer, with their growth usually stabilizing between twelve to fifteen months. Standard Cockapoos, being the largest size category, may continue growing until they are 18 months old.

To ensure healthy growth and development, it is crucial to provide Cockapoos with a balanced diet, regular exercise, and proper veterinary care. Feeding them high-quality dog food appropriate for their size and age is essential. Consult with your veterinarian to determine the most suitable diet and feeding schedule for your Cockapoo.

Monitoring your Cockapoo’s weight and body condition is also important. Obesity can lead to health issues and should be avoided. Regular exercise, such as daily walks or play sessions, helps maintain a healthy weight and promotes overall well-being.


Cockapoos come in different sizes, ranging from Toy Cockapoos to Miniature Cockapoos and Standard Cockapoos. While individual growth patterns may vary, most Cockapoos stop growing and reach their full size by one year to 18 months of age. Understanding their growth stages and providing them with appropriate care, including a balanced diet, exercise, and regular veterinary check-ups, is crucial to ensure their healthy development. By being aware of their growth patterns, you can better anticipate and adapt to their changing needs as they transition from adorable puppies to cherished adult companions.
