How big does a Cavapoo get?

Why doesn't a Cavapoo have a standard size?

Because it's a cross, and an official height is only written down for purebreds. The Cavalier King Charles Spaniel has one and the Poodle has one, but nobody official has ever said how tall a Cavapoo should stand.

That's the tradeoff with a cross. A purebred is more predictable in size, coat, care and temperament, and a Cavapoo gives up some of that, which is why we estimate each puppy's grown weight from its own mama and papa and never from a chart. You'll find the estimate on every puppy's page, next to the names of both parents.

How big are a Cavapoo's parent breeds?

The Cavalier is small and consistent, and the Poodle depends on which size it is. A Cavalier stands 12 to 13 inches at the shoulder and weighs 13 to 18 pounds, while the Poodle comes in three sizes. A Miniature Poodle stands over 10 inches and up to 15, at 10 to 15 pounds, and a Toy Poodle stands 10 inches or under and weighs 4 to 6 pounds.

Side by side, the Cavalier and the Miniature Poodle are close in size, with weights that overlap between 13 and 15 pounds. The papa behind our F1B Cavapoos is a Miniature Poodle, and each puppy's page gives the breeds of both its parents, which shows you exactly which sizes went into it.

What will our Cavapoos weigh?

Our Cavapoos are expected to reach 15 to 20 lbs and our F1B Cavapoos 13 to 15 lbs, going by the puppies on our site now. Each puppy's own page narrows that to a range for that puppy, worked out from its parents.

Our Cavapoo mamas weigh 8 to 16 lbs and our Cavalier mamas 16 to 26 lbs, and those grown dogs are the best preview we can give you. We're careful with our estimates, and they're still estimates, so read the health guarantee page for exactly what we can and can't promise about size.

When you shop for a crate or a harness, plan around the top of the range and adjust as your puppy fills out.

When does a Cavapoo stop growing?

Expect a Cavapoo to be close to its grown size by its first birthday. Small-breed dogs usually finish growing somewhere from 6 to 12 months old, and for some very small dogs the fastest growth is over by 6 to 8 months.

Those months go quickly, so plan on buying more than one collar. Weigh your puppy now and then and bring the numbers to your vet visits. Your vet can tell you whether growth is on track and when to switch your puppy to an adult food.

How long do Cavapoos live?

There's no official figure for a Cavapoo, so the parent breeds are the starting point. A Cavalier usually lives 12 to 15 years and a Miniature Poodle 10 to 18.

A large study of more than half a million dogs found a typical lifespan of 11.8 years for Cavaliers, 14 years for Poodles, and 12 years for mixed breeds as a group. That's the midpoint, so half of each group lived longer.

Weight is the part a family controls. Breed for breed, overweight dogs tend to live shorter lives than dogs kept at a healthy weight, so a trim Cavapoo is worth aiming for from the start.
