Cavapoo Growth Stages

Understanding the typical growth stages helps you know what to expect as your Cavapoo puppy grows.

Neonatal

0–2 weeks

Puppies are born with eyes and ears closed, relying entirely on their mother. Rapid weight gain occurs during this period.

Socialization

3–12 weeks

Eyes and ears open. Puppies begin to explore, play, and learn social behaviors. This is a critical period for development.

Juvenile

3–6 months

Rapid growth continues. Puppies become more independent, start teething, and develop coordination.

Adolescent

6–10 months

Growth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.

Young Adult

10–12 months

Growth is nearly complete. Your puppy is filling out and approaching adult proportions.

Adult

12+ months

Your puppy has reached their full adult size. Weight should remain relatively stable with proper nutrition.

Cavapoo FAQ

How much will my Cavapoo puppy weigh as an adult?

Most adult Cavapoos typically weigh between 10 and 20 lb. Males often land in the 12–20 lb range, while females may finish lighter at 10–18 lb.

At what age is a Cavapoo fully grown?

Cavapoos usually reach adult weight between 10 and 12 months. They often look full-sized a little earlier.

How accurate is a Cavapoo puppy weight chart?

Charts show typical trends, not guarantees. Toy versus miniature Poodle parents shift the range, so ask your breeder for parent weights to refine the estimate.

Do male and female Cavapoos grow differently?

Males run a couple of pounds heavier on average. Both sexes stay in the same small companion range.

How much should I feed my Cavapoo puppy?

Feed measured meals of a quality small-breed puppy food. Cavapoos gain weight easily, which strains the heart — a real concern given the Cavalier side. Ask your vet about portions.
