Cavapoo Full Grown Sizes
A full grown Cavapoo weighs 7 to 30 pounds and stands 9 to 18 inches tall at the shoulder. Where your puppy lands in that range depends mostly on the Poodle parent: Toy Poodle parents make Toy Cavapoos, Miniature Poodles make Mini Cavapoos, and Standard Poodles make Standard Cavapoos. Most Cavapoos reach their adult height by 10 to 12 months and finish filling out by 14 to 18 months. If you're already searching for Cavapoos for sale, understanding their size first can help you choose the right fit for your family and home.
Cavapoo Size Chart
Teacup Cavapoo (not an official size): under 7 pounds, under 9 inches tall
Toy Cavapoo: 7-13 pounds, 9-12 inches tall
Miniature Cavapoo: 13-20 pounds, 12-16 inches tall
Standard Cavapoo: 20-30 pounds, 15-18 inches tall
These ranges overlap because every litter mixes two breeds. A puppy from a Toy Poodle and a Cavalier can end up anywhere from a small Toy to a small Mini. Heights are measured at the shoulder.
Toy Cavapoo Full Grown
The toy Cavapoo is the most popular Cavapoo size. People love lap dog size, plus Cavapoos characteristics show they are very snuggly, so they are the perfect small dog breed for apartments and families who want a dog they can easily carry. A full grown Toy Cavapoo weighs 7 to 13 pounds and stands 9 to 12 inches tall at the shoulder. Most reach their adult height around 10 months.
Miniature Cavapoo Full Grown
Miniature Cavapoos are perfect for people who want a small dog but don't want a tiny dog. They're sturdier around kids and hold up better on longer walks. Full grown, they weigh 13 to 20 pounds and stand 12 to 16 inches tall.
Standard Cavapoo Full Grown
Standard Cavapoos are the biggest of the bunch. They're one of the best options for active families with kids, because they're sweet and gentle, and big enough that typical rough play from kids is less likely to hurt them. A full grown Standard Cavapoo weighs 20 to 30 pounds and stands 15 to 18 inches tall. Standards are less common, because most breeders pair Cavaliers with Toy or Miniature Poodles.
Teacup Cavapoos
"Teacup" isn't an official size. It usually means a Cavapoo expected to stay under 7 pounds as an adult. Very small puppies need closer care: they're more prone to low blood sugar as puppies, get hurt more easily from falls, and feel the cold more. If you want a very small Cavapoo, ask the breeder for the parents' actual weights instead of relying on the label.
Cavapoo Growth Chart by Age
Cavapoo puppies grow fastest in their first 4 months. A good rule of thumb: at 4 months a Cavapoo weighs about half its adult weight, and at 6 months about three quarters. Here's what to expect for each size.
Toy Cavapoo (7-13 pounds full grown)
8 weeks: 2-3 pounds
3 months: 3-5 pounds
4 months: 4-6 pounds
6 months: 5-9 pounds
9 months: 6-11 pounds
12 months: 7-13 pounds
Miniature Cavapoo (13-20 pounds full grown)
8 weeks: 3-5 pounds
3 months: 5-8 pounds
4 months: 7-10 pounds
6 months: 10-14 pounds
9 months: 12-18 pounds
12 months: 13-20 pounds
Standard Cavapoo (20-30 pounds full grown)
8 weeks: 5-7 pounds
3 months: 8-12 pounds
4 months: 10-15 pounds
6 months: 15-22 pounds
9 months: 18-27 pounds
12 months: 20-30 pounds
When Is a Cavapoo Full Grown?
Most Cavapoos reach their full height between 10 and 12 months. They keep adding a little muscle and weight until 14 to 18 months, and Standards can take the full 18 months. After that, weight changes come from diet and exercise, not growth.
What Determines How Big a Cavapoo Will Be
The Poodle parent. This matters most. Poodles come in Toy, Miniature and Standard sizes, while Cavaliers stay fairly consistent at 13 to 18 pounds. Selective breeding over many generations is what created smaller Poodles, and in turn smaller Cavapoos. If you are curious about the science behind these facts, it's worth a read.
Generation. An F1 Cavapoo (Cavalier crossed with Poodle) usually lands between its parents. An F1b Cavapoo (Cavapoo crossed back to a Poodle) tends to follow the Poodle side more closely, in size as well as coat.
Gender. Males are often slightly larger than females, but the difference is small compared to the effect of the parents.
Food. Feeding less will not make a Cavapoo smaller. It only makes an underweight, unhappy puppy.
Real Examples From Our Parent Dogs
We list the height and weight of every parent dog on our site, and every litter comes with an expected adult size based on both parents. Here are two of our current Cavapoo litters:
Ruby and Scotch: Ruby is a 14 pound Toy Poodle (9 inches) and Scotch is a 9 pound Cavapoo (11.5 inches). Expected adult size: 10-14 pounds.
Pebbles and Scotch: Pebbles is a 16 pound Miniature Poodle (12 inches) and Scotch is a 9 pound Cavapoo (11.5 inches). Expected adult size: 16-18 pounds.
Our Cavalier sire, Buddy, stands 12.5 inches and weighs 12 pounds.
How to Estimate a Cavapoo's Adult Size
Check both parents. Ask for each parent's actual weight and height, not just the breed.
Weigh your puppy at 16 weeks. Doubling that number gives a rough estimate of adult weight.
Compare against the growth chart above. A puppy tracking near the top or bottom of its range usually stays there.
Monitor diet and health. Good nutrition helps your puppy reach its natural size. It won't change that size.
Consult your vet if growth seems unusually fast or slow.
Keeping Your Cavapoo Healthy
Depending on how big your Cavapoo is, you will have to care for them differently. A bigger Cavapoo needs more exercise and food. A smaller Cavapoo needs you to watch them closer, since small dogs are more sensitive to loud noises and can get hurt more easily. Keeping a small dog healthy can sometimes be harder than a standard-sized dog. Cavapoos are considered a healthy breed, but it is a good idea to be aware of the health issues that are more common for Cavapoos.
You will also want to make sure you are giving your Cavapoo the right amount of food to give your Cavapoo for its age and size. Some people restrict food in hopes of a smaller Cavapoo, but this only gives you an unhealthy, short-tempered puppy that chews on everything.
Grooming Tips by Coat Type
Cavapoos can have curly, wavy or straight coats. Curly coats take after the Poodle and need brushing every day to prevent mats. Wavy coats need brushing every 1-2 weeks. Straight coats, closer to the Cavalier King Charles Spaniel, are the easiest to groom but may shed more. A slicker brush works best for detangling, a soft bristle brush for smoother coats, and a professional groom every 6-8 weeks keeps any coat in top condition.
