Cavapoo Size Guide: How Big Will My Cavapoo Get?
Toy or miniature? 8 lbs or 20? Your Cavapoo's adult size depends on parent genetics, generation, and a few other factors — here's exactly how to predict it.

The Two Main Cavapoo Size Categories
Cavapoo size is primarily determined by which type of Poodle parent was used. Cavaliers weigh 12–18 lbs, so the Poodle parent's size is the key variable:
- Toy Cavapoo (Cavalier × Toy Poodle): Toy Poodles weigh 4–7 lbs. F1 puppies typically mature at 9–15 lbs.
- Miniature Cavapoo (Cavalier × Miniature Poodle): Mini Poodles weigh 10–20 lbs. F1 puppies typically mature at 14–22 lbs.
How Generation Affects Size
F1B Cavapoos (75% Poodle) will skew toward the Poodle parent's size, producing slightly smaller Toy Cavapoos or more Poodle-proportioned Miniature Cavapoos. F2 Cavapoos can have more genetic variance — size can range more widely in the same litter. Multigenerational Cavapoos bred from consistently sized parents are the most size-predictable.
The 'Teacup' or 'Tiny' Cavapoo: An Honest Assessment
Some breeders advertise 'teacup' Cavapoos as a smaller variant. This is not a real size category and is not genetically defined — it refers to runts or to dogs produced by breeding smaller-than-average specimens together. Extreme miniaturization increases the risk of fragility, hypoglycemia, dental overcrowding, tracheal collapse, and shortened lifespan. We don't breed for extreme small size. Our Toy Cavapoos are naturally small without being fragile.
Growth Timeline: When Do Cavapoos Stop Growing?
- 4 weeks: Puppy weight roughly doubles from birth
- 8 weeks: Approximately 25–30% of adult weight
- 4 months: Approximately 50% of adult weight
- 6 months: Approximately 70% of adult weight
- 12 months: Most Cavapoos have reached adult weight
- 18 months: Final adult weight confirmed — some slow-maturing dogs fill out slightly between 12–18 months
The Parent Weight Rule of Thumb
A reliable estimate for F1 Cavapoo adult weight: add both parent weights together and divide by two. A 6 lb Toy Poodle × 15 lb Cavalier = an average expected adult weight of about 10.5 lbs. Individual puppies within the same litter can vary by 20–30% from this estimate based on which parent's genetics are more dominant.
