Cavapoo Adult Weight Calculator
A delightful cross between a Cavalier King Charles Spaniel and a Poodle, known for being incredibly affectionate.
Cavapoo reference information
Most Cavapoos reach their adult weight by 8 to 12 months, depending heavily on the size of the Poodle parent.
The ranges below are general planning references used by this site. Individual dogs may fall outside them, especially crosses and dogs whose breed label is uncertain.
How this breed selection changes the estimate
The breed selection chooses the small distribution derived from veterinary records. If sex is selected, it uses the matching male or female curve; otherwise it uses the combined-sex curve. The central estimate comes only from the puppy's measurement and the data-derived growth fraction.
The listed Cavapoo reference range is shown beside the result but is not blended into or forced onto it. A disagreement can be useful: it may reflect uncertain ancestry, an unusual line, body condition, inaccurate age or weight, or ordinary individual variation.
Cavapoo example growth path
The table below starts with an illustrative adult weight of 18 lb—the midpoint of the listed male and female planning ranges—and applies the small distribution. It is not a target for every Cavapoo; it shows how the calculator's source data translate an adult outcome back into puppy-age measurements.
| Age | Median path | Observed 10th–90th percentile path | Training dogs |
|---|---|---|---|
| 8 Weeks | ~ 5 lbs | 3–6 lbs | 7,259 |
| 12 Weeks | ~ 7 lbs | 5–9 lbs | 13,503 |
| 16 Weeks | ~ 9 lbs | 7–11 lbs | 15,495 |
| 24 Weeks | ~ 13 lbs | 10–15 lbs | 9,846 |
| 36 Weeks | ~ 15 lbs | 13–18 lbs | 4,472 |
| 52 Weeks (1 Year) | ~ 17 lbs | 14–19 lbs | 4,363 |
| 76 Weeks (1 Year+) | ~ 17 lbs | 15–19 lbs | 5,506 |
Evidence behind the estimate
The curve tables were derived from 299,711 dogs with eligible puppy visits and a young-adult outcome, then evaluated on a separate 75,648-dog holdout group. Every result reports the relevant sample size and age-band error. See the validation report and complete methodology.
Use measurements for fit and health decisions
Do not use predicted adult weight to choose a medication dose, feeding amount, collar, harness, or crate. Use current body measurements, product instructions, and professional guidance. Ask a licensed veterinarian about unexpected growth or body-condition changes.
