Cavapoos, also known as Cavadoodles, are a mix between a cavalier king charlies spaniel and a poodle. However, poodles vary in size substantially. There are toy, miniature, and standard poodles. Therefore, cavapoos vary in size, too.

Here are the general guidelines for cavapoo sizes:

  • Toy Cavapoos: These are the smallest cavapoos. They are typically bred using a toy poodle and a smaller cavalier king Charles spaniel. They can weigh between 7 to 13 pounds and stand around 9 to 12 inches at the shoulder.
  • Miniature Cavapoos: Typically, these dogs fall between the toy and standard sizes. They are bred from a miniature poodle in most cases. Their weight can range from 13 to 20 pounds, and they stand between 12 to 16 inches at the shoulder.
  • Standard Cavapoos: These are the largest Cavapoos, as they are bred from a standard poodle. Their weight can range from 20 to 45 pounds, and they can stand between 16 to 18 inches at the shoulder.

Cavapoo Summary

Cavapoos are a mixed breed that combines a cavalier king charles spaniel and a poodle. Because these dogs are a mixed breed, you’ll never quite know what these dogs will look like, including what their size will be.

They’re often bred because of the misconception that they are hypoallergenic. However, its important to realize that different dog breeds do not produce more or less allergens than others.

Cavapoo Growth and Weight Chart by Age

Here’s a general overview of the average weight range for Cavapoos at various ages. Keep in mind that individual dogs may vary, but this chart provides a rough idea of what to expect:

When Will My Cavapoo Stop Growing?

Cavapoos usually grow very fast for the first few months, doubling their weight many times over. However, their growth rate usually slows down around 6 months. By the time they reach one year old, most Cavapoos have gained most of their growth rate.

Smaller dogs will reach their full weight faster than larger dogs. It simply takes longer to put on the pounds if you have more pounds to put on.

How Big Will My Cavapoo Be When It’s Fully Grown?

How big your Cavapoo will get depends on a range of different factors, such as the dog’s genetics and diet. The size of their poodle parent also matters a lot. Here’s an estimate of how big your dog might get.

  • Toy Cavapoo: About 9 – 12 inches tall and 7 – 13 pounds
  • Miniature Cavapoo: Around 12 – 16 inches tall and 13 – 20 pounds
  • Standard Cavapoo: About 16 – 18 inches tall and 20 – 35 pounds

When Should My Cavapoo Be Spayed or Neutered?

The recommended age for spaying or neutering your Cavapoo is typically around 6 months. Once they reach a big enough size to avoid unnecessary complications, it’s best to get them spayed or neutered. Usually, this happens around 6 months.

You want the dog spayed or neutered before they reach sexual maturity. This procedure prevents accidental breeding and a slew of health problems.

Breeding dogs is challenging and requires extensive knowledge. Therefore, unless you’re working alongside a knowledgeable breeder, it is best to get your pet fixed.

When Should My Cavapoo Be House Broken?

You should start trying to house-train your Cavapoo as soon as you bring them home. Eight weeks is not too young to start training. In fact, many breeders will begin training before they even send their puppies to their forever homes.

It’s important to remain consistent and dedicated to house training, as it can be challenging. Smaller dogs tend to take longer, as they have smaller bladders. However, that doesn’t mean that you should wait.

Waiting on house training can cause bad habits to form, which can be challenging to break.

When Should My Cavapoo Stop Eating Puppy Food?

Most Cavapoos can transition from puppy food to adult food between 10 and 12 months of age. You want to keep them on puppy food until they have reached their adult size, which can vary from dog to dog. Once your dog stops putting on weight, you can safely stop the food (usually). However, always consult your vet when you’re in doubt.

It’s typically best to continue puppy food a bit longer than necessary than to switch them to their new food too soon.

When Will My Cavapoo Start Losing Teeth?

All dogs start losing their teeth at about the same time. Cavapoos typically start losing their puppy teeth around 3 – 4 months of age. By 6 months, they should have most of their adult teeth.

However, this can vary. Most of the time, puppies being a bit early or late isn’t a problem.

When Should I Start Training My Cavapoo?

Always begin training as early as possible. You want to teach your Cavapoo how training works; the only way to do that is to train them. Socialization and basic obedience training should be begun as soon as you bring your puppy home.

However, don’t exact a lot from your puppy at first. Puppies have very short attention spans, so keep training to 2 – 3 minutes. Make it fun so that your dog looks forward to training, which will be very helpful in the future.

What Cues Should I Teach My Cavapoo First?

Start with essential commands like “sit,” “stay,” “come,” and “down.” Positive reinforcement and short training sessions work best. These commands are simply necessary for dogs to learn other commands, and they are often the easiest to learn.

When Will My Cavapoo Calm Down?

Cavapoos usually start to show increased calmness and maturity around 1 – 2 years of age. However, individual dogs can vary, and consistent training and exercise are crucial for managing their energy.

Be sure to always focus on your dog’s needs, especially their exercise and mental stimulation needs. When these are met, dogs tend to be much calmer.

Common Health Issues Your Cavapoo Might Experience

Cavapoos, like many breeds, can be prone to certain health issues such as heart problems, ear infections, and dental issues. Choosing a good breeder that takes the dog’s health into account before breeding can help lower the chance of genetic defects, like those common in heart disease.

Taking proper care of your dog can help, too. For instance, you may want to keep the inside of their ears clipped short to help prevent ear infections, as the fur can trap debris and moisture. Keeping your dog’s teeth and ears clean can help prevent problems, too.
