So, depending on the type of Cockapoo in question, this breed can be a variety of sizes. Here is everything that you need to know about this unique mixed designer breed.

Facts About the Cockapoo

Cockapoos are well known for being comical, and their lively attitudes and laidback personalities make them a joy to spend time with. A Cockapoo may display more features of one of their parents than the other, so it is hard to predict exactly what a puppy will look like when they are fully grown. Here are a few facts that you should know about Cockapoos:

  • They have plenty of energy and can spend many hours each day playing and running around. They require daily walks and outdoor playtime to stay happy and healthy throughout their life.
  • Cockapoos typically have long, droopy ears that are prone to infection, so these must be cleaned with a damp cloth or cotton balls regularly. Trimming the hair that grows out of their ears may also help.
  • These dogs have a keen talent for making their human parents feel guilty! All they have to do is tilt their head and look at you with droopy eyes to make you give in to whatever their wishes are.

Cockapoo Size and Growth Chart

There are multiple types of Cockapoos. Although none are considered large, their weights and sizes do vary significantly. The weight range can vary from about 5 to 40 pounds. Here are the specifics:

Teacup Toy Miniature Standard
Puppy Height 5 inches 5 inches 6–8 inches 8–10 inches
Puppy Weight 2–4 pounds 4–6 pounds 6–7 pounds 10–12 pounds
Adult Height Under 10 inches 10–11 inches 11–14 inches 15–18 inches
Adult Weight 5–7 pounds 10–12 pounds 13–15 pounds 19–40 pounds

When Does a Cockapoo Stop Growing?

A Cockapoo typically stops growing at about 1 year of age, but this can vary depending on the type of dog. The smaller dogs tend to grow into adulthood sooner than the standard version, which can take up to 2 years to fully develop. Every dog grows slightly differently, so it might take your dog more or less time than expected to become fully grown.

Factors Affecting the Size of Cockapoos

There are a few things that can affect the size of a Cockapoo in addition to the type of Cockapoo that they happen to be. Naturally, toy Cockapoos are going to be smaller than standard Cockapoos when all is said and done. Diet can also play a role in overall size. If a pup isn’t getting the nutrients that they need, they may not reach their full weight and height potential.

Spaying or neutering a Cockapoo early can also affect the height and weight of a Cockapoo as an adult.

Ideal Diet for Maintaining a Healthy Weight

Cockapoos should eat a high-quality diet made up of real meat protein and a healthy source of carbohydrates. When your dog is young, it’s important to choose a commercial food that is made specifically for puppies, as it is formulated with more protein and calories than adult food to help with the growing process. As your pup grows into adulthood, you can slowly transition them to commercial food for adults, which is any kind that’s not labeled specifically for puppies or senior dogs.

How to Measure Your Cockapoo

You may want to measure your Cockapoo to see how much they are growing as they make their way to adulthood. Properly measuring your dog should also help make it easier to choose the right-sized collars, harnesses, and clothing for them as they grow.

To measure your Cockapoo, you need a fabric measuring tape for optimal accuracy. It’s also a good idea to maintain a notebook so that you can record measurements for reference later. Here’s how to measure your Cockapoo:

  • Body Length: To measure your dog’s length, place one end of your measuring tape against the base of their tail and the other end at the beginning of their neck, being careful to avoid the full neck and head while you measure.
  • Chest Girth: To determine this measurement, wrap the measuring tape around the widest section of your dog’s chest, between the shoulder blades and the forelegs. Read the measurement at this point to determine girth.
  • Height: The easiest way to determine your dog’s height is to get them to stand tall against a wall (treats can help with this process). Then, place a level, straight stick, or similar item against the wall right where the highest point of the shoulder blades is located. Keep the level in place and let your dog move away. Measure the space between the floor and the level to determine their height.
  • Neck Girth: Lightly wrap the measuring tape around the base of your dog’s neck, right where it meets the chest, to determine the girth of your dog’s neck.



Now, you should be able to gain insight into how big your cockapoos will get when they are fully grown. However, many factors come into play where weight and size are concerned. Therefore, it’s important to keep in mind that your dog may be bigger or smaller than anticipated.
