Cavoodles are one of Australia’s favourite small dog breeds, no question. But how small is small, exactly?
If you are thinking of getting one, you will want to know how big they grow, when they stop, and what size to expect from the parents. Let us look at how big a Cavoodle really gets.
Cavoodles are small dogs
A Cavoodle is classed as a small dog, which means they fit comfortably in your lap. That size makes them a great house pet for families and singles alike, and it suits apartment life too, as long as they get their daily walks and plenty of exercise. That last part matters, because for a small dog a Cavoodle has energy to burn.
They are not quite chihuahua-in-a-handbag small, but a Cavoodle is easy enough to carry when you need to. They do not get much taller than about 38cm at the shoulder, and most sit comfortably under 12kg, so they are an easy dog to have around.
The difference between Toy and Mini Cavoodles
Cavoodle size comes down mostly to which type of Poodle is in the mix. A Cavoodle can be bred using either a Toy Poodle or a Miniature Poodle, and that choice shapes the size of the pup. A Toy Poodle generally stands around 24 to 28cm, while a Miniature Poodle is taller at roughly 28 to 35cm, and the Cavoodle takes after that to a degree.
A Toy Cavoodle is the smaller of the two. Fully grown, they usually weigh around 4 to 7kg and stand roughly 25 to 35cm at the shoulder. They are laid back little lap dogs that make up for shorter legs by curling up on you at every opportunity. Cute, compact and full of fluff.
A Mini Cavoodle is a bit bigger, generally weighing around 7 to 12kg and standing about 30 to 38cm at the shoulder. They tend to be a touch sportier and more energetic, which makes them a great walking or jogging companion if you are an active sort.
The difference between the two is often smaller than people expect, and genetics can throw up surprises, so a Toy parent can occasionally produce a pup at the larger end and the other way around. A good breeder can give you a fair idea of the size to expect based on the parents.
When do Cavoodles stop growing?
Small dogs like the Cavoodle usually reach their full height by around 10 to 12 months of age. Many keep filling out and gaining a little muscle for a few months after that, but the bulk of the growing is done inside the first year.
How to tell how big your Cavoodle will grow
The best way to estimate a puppy’s adult size is to look at their parents. When one parent is a Toy Poodle, you can expect the pup to land in the Toy Cavoodle range, and when one is a Miniature Poodle, most likely a Miniature Cavoodle. The size of the parents is almost always a good guide.
Sizes outside the norm
It is uncommon to find a Cavoodle much taller than 40cm or heavier than 12kg. A little variance is fine, a kilo or a couple of centimetres either way, but much more than that is worth a closer look.
If your Cavoodle is a normal height but heavier than expected, it could be a weight issue, so check with your vet, since it is usually sorted with a tweaked diet and more exercise. If your pup is a good deal taller than average, it may mean they are not a pure Cavoodle and have other breeds in the mix, which is one more reason to buy from a reliable, verified breeder.
Which size is best?
Toy and Mini Cavoodles are much of a muchness in personality. Both are loving, playful and loyal, and both want to be by your side. Their needs are similar too, with the main difference being how much they eat. A smaller dog has a slightly more delicate build, though that does not necessarily mean more delicate health. There are a few health issues to keep an eye on with each, but those come down more to the parents’ genetics than the size itself.
The perfect size for your home
Whichever type you go for, a Cavoodle is a great fit for just about any family. Being small makes them safe and gentle around children and other pets, sturdy enough for a busy household, and just the right size to share your home. They do not need much space, so as long as they are getting their daily walks, your Cavoodle will be a happy dog, equally at home in a large house or a compact apartment.
With their compact size and a weight that rarely tips much over 12kg, Cavoodles are a wonderful fit for almost any home. They do not get very big, but they make a big impact on your life, fitting neatly into your house, your lap and your heart.
