Cavapoo Weight Calculator

The Cavapoo (also called a Cavoodle) is a designer crossbreed of a Cavalier King Charles Spaniel and a Poodle. It was bred to combine the sweet, people-loving temperament of the Cavalier with the low-shedding coat of the Poodle, and it has become one of the most popular companion crosses in the US and UK.

Because a Cavapoo is a mix, its adult size is not fixed the way a purebred's is. The single biggest factor is which Poodle was used. A Toy Cavapoo (from a Toy Poodle parent) stays small at 7–13 lbs, while a Miniature Cavapoo (from a Miniature Poodle parent) reaches 13–25 lbs. Most fall in a typical adult range of 12–20 lbs. The calculator above reflects a typical Miniature Cavapoo, the most common size sold.

A full grown Cavapoo typically weighs 12–20 lbs (5.4–9.1 kg) and stands about 9–14 inches tall at the shoulder. The two common size classes come from the Poodle parent:

• Toy Cavapoo: 7–13 lbs (3.2–5.9 kg), roughly 9–12 inches tall. Bred from a Toy Poodle parent.
• Miniature Cavapoo: 13–25 lbs (5.9–11.3 kg), roughly 12–14 inches tall. Bred from a Miniature Poodle parent.

Males usually run slightly heavier than females within either class. There is real overlap between the sizes, so a small Miniature Cavapoo and a large Toy Cavapoo can end up the same weight. If you know the size of both parents, you have the most reliable guide to your puppy's adult weight.

The calculator above generates a full growth chart for your Cavapoo by age and sex. Enter your dog's details to compare its current weight against the expected range at each milestone. The table reflects a typical Miniature Cavapoo; Toy Cavapoos track along the lower end or below it.

As a rough guide, a Miniature Cavapoo grows fastest between 8 weeks and 6 months, reaching roughly two-thirds of its adult weight by the half-year mark. Growth then slows sharply, with the last pound or two of adult weight added between 8 and 12 months. If your puppy is tracking well above the top of its range at every check, review portions early rather than waiting.

Most Cavapoos reach their near-adult size by 8–9 months and are fully grown by 10–12 months. Height is usually settled first; the chest and muscle fill out last. Toy Cavapoos tend to finish a little earlier because smaller dogs mature faster, while larger Miniature Cavapoos may keep adding a small amount of weight up to around their first birthday.

After 12 months, any noticeable weight gain is almost always fat rather than growth. Once your Cavapoo hits its adult range, use the body condition guidance below to keep it there.

Cavapoos are labeled by generation, and the generation changes what you can expect from size, coat, and shedding:

• F1 Cavapoo: a 50/50 first cross of a purebred Cavalier and a purebred Poodle. F1 litters show the widest variation in size and coat, and coats range from wavy to loosely curled. They may shed a little more than higher-Poodle generations.
• F1b Cavapoo: an F1 Cavapoo bred back to a Poodle, so the dog is about 75% Poodle. This produces the curliest, lowest-shedding coats and is the usual pick for allergy households. F1b dogs often trend slightly smaller if bred back to a Toy Poodle.
• F2 Cavapoo: two F1 Cavapoos bred together. Genetics reshuffle, so F2 litters can produce the broadest range of coat types and sizes, including some straighter, higher-shedding coats.

Generation affects coat more predictably than size. Size is still driven mainly by the Poodle lineage (Toy vs Miniature) behind the cross.

A typical adult Cavapoo eats roughly 1/2 to 1 cup of quality dry food per day, split into two meals, with the exact amount set by adult weight and activity level. A 10 lb Toy Cavapoo needs meaningfully less than a 22 lb Miniature Cavapoo, so feed by your dog's weight, not by the size of the bag's scoop.

Puppies need more frequent meals: three to four small meals a day through about 6 months, then two meals a day. Cavapoos are small and very food-motivated, which makes overfeeding easy. Measure every meal, keep treats under 10% of daily calories, and use our Dog Nutrition Calculator to set a precise daily amount.

As a cross, a Cavapoo can inherit health conditions from either parent breed. The ones responsible owners watch for are:

• Patellar luxation: a slipping kneecap common in small dogs. Keeping your Cavapoo lean reduces the load on the joint and the risk of surgery.
• Mitral valve disease (MVD): a heart condition inherited from the Cavalier King Charles line, where the heart's mitral valve degenerates over time. Regular cardiac checks and staying lean lower the strain on the heart.
• Syringomyelia: a neurological condition linked to skull shape in the Cavalier line, where fluid-filled cavities form near the spinal cord. Signs include neck scratching and sensitivity, and it is worth discussing parental screening with your breeder.
• Progressive retinal atrophy (PRA): an inherited eye disease that gradually reduces vision. A DNA test can confirm whether the parents are clear.

Buying from a breeder who health-tests both the Cavalier and the Poodle parent is the single best way to lower these risks. Because several of these conditions are weight-sensitive, keeping your Cavapoo at a healthy weight is genuinely protective.

A Cavapoo's wavy or curly coat hides weight changes, so assess body condition by feel, not by sight. Run your hands firmly along the ribcage once a month. The three-point guide below shows what a healthy Cavapoo should feel like.

Cavapoos are classic velcro companion dogs. They inherit the Cavalier's need for closeness and the Poodle's intelligence, so they are affectionate, quick to learn, and happiest at your side. They are gentle and patient, which makes them a strong choice for families with children and for first-time owners.

They adapt well to apartment living thanks to their small size and moderate energy: a daily walk plus play and short training sessions covers their needs. The flip side of their devotion is that Cavapoos dislike being left alone for long periods and can develop separation anxiety, so they suit households where someone is around for much of the day.
