At what age do Cavapoos reach full size

When welcoming a Cavapoo puppy into your home, one of the most common questions is: At what age do Cavapoos reach full size? Understanding your Cavapoo’s growth timeline helps you provide the right care during their critical development phases. In this comprehensive guide, we’ll explore how Cavapoos grow, the factors that affect their size, and what you can expect as your puppy matures into a full-grown adult.

Key Takeaways

Cavapoos generally reach their full adult size between 12 to 18 months, with some filling out until about 24 months.
Size depends on whether your Cavapoo is from a Toy or Miniature Poodle lineage, plus genetics and nutrition.
Monitoring growth helps catch any health issues early, including joint conditions like luxating patella.
Proper diet, exercise, and vet care during puppyhood support healthy development.
Understanding their growth stages leads to better training and wellbeing for your Cavapoo.

What Determines When a Cavapoo Reaches Full Size?

Cavapoos are a designer crossbreed between the Cavalier King Charles Spaniel and the Miniature or Toy Poodle. This blend creates some variation in size and growth rates depending on the parent breeds involved.

Genetics: The size of the parents largely determines how big your Cavapoo will grow. A Toy Poodle parent typically means a smaller puppy, while a Miniature Poodle tends to produce a slightly larger dog.
Nutrition: Feeding your Cavapoo a balanced, high-quality diet during their growing months supports proper bone and muscle development.
Exercise: Regular but controlled exercise helps develop strong muscles and joints without stressing growing bones.
Health: Certain health conditions, such as hip dysplasia or luxating patella—a common joint problem in small dogs—can impact mobility and development. Monitoring your puppy’s growth and movement can alert you to issues early. For detailed information on luxating patella in dogs, you can check this vet-reviewed guide.

Cavapoo Growth Timeline: From Puppy to Adult

Birth to 6 Months: Rapid Growth Phase

During the first six months, your Cavapoo puppy will experience a rapid increase in both height and weight. Bones, muscles, and organs grow quickly, so providing a nutritious diet rich in protein, calcium, and essential vitamins is critical.

Puppies typically double or triple their birth weight by 8 weeks.
This stage involves teething, so safe chew toys are necessary to soothe discomfort.
Socialization and training are vital at this stage to foster confidence and good habits.

6 to 12 Months: Slower Growth and Refinement

Growth rate slows between six months and one year, but your Cavapoo will still gain weight and fill out. By around 12 months, most Cavapoos reach close to their full adult height but might not be fully mature in muscle and body shape.

Their adult coat begins to develop, often softer and curlier if Poodle genes are dominant.
Behaviorally, they may go through adolescent phases, testing boundaries and independence.
Joint health is crucial now—avoid strenuous exercise that could harm developing cartilage.

12 to 24 Months: Final Maturation

While height plateaus around 12 months, some Cavapoos continue to fill out and gain muscle definition until 18-24 months. Males often take longer to mature fully compared to females.

Physical maturity is reached during this time, but mental maturity might take longer.
Continued training, socialization, and regular vet checkups keep your Cavapoo healthy and well-adjusted.

Average Adult Size of Cavapoos

Height: 9 to 14 inches (23 to 36 cm) at the shoulder
Weight: 12 to 25 pounds (5.5 to 11.3 kg)

These ranges vary depending on the mix of Toy vs. Miniature Poodle genes and individual differences.

Signs Your Cavapoo Is Approaching Full Size

Growth spurts become less frequent and less pronounced.
Puppy energy shifts into more controlled, adult-like behavior.
Physical proportions—head, body, legs—start balancing out.
Your Cavapoo’s weight stabilizes, no longer gaining significant pounds.

How to Support Healthy Growth in Your Cavapoo

Feed high-quality puppy food formulated for small breeds to support bone and muscle growth.
Schedule regular vet visits for growth tracking and vaccinations.
Provide safe exercise like short walks and supervised playtime to build strength without strain.
Avoid excessive jumping or rough play to protect joints, especially during growth spurts.
Watch for signs of discomfort such as limping, reluctance to move, or excessive licking of joints.

Frequently Asked Question

Q: My Cavapoo is 14 months old but still seems small—is this normal?
A: Yes, it can be normal. Some Cavapoos, especially those with Toy Poodle lineage, take longer to fully mature and fill out. If your puppy appears healthy and active, there’s usually no cause for concern. However, if you notice limping or unusual behavior, consult your vet to rule out any growth or joint issues.
