How big do Cavachons get? The tool below projects your own puppy’s adult weight from its current age and weight, plotted against the typical Cavachon growth curve.
Estimates combine your puppy’s current trajectory with typical growth curves for this breed and size class. Individual dogs vary — nutrition, genetics and neuter timing all matter. For health concerns, ask your vet.
The Cavachon is a toy-sized breed. Adult males typically weigh 10–20 lb (4.5–9.1 kg) and females 10–18 lb (4.5–8.2 kg). Most Cavachons reach about half their adult weight around 3.2 months, hit 90% by roughly 6.7 months, and are fully grown near 9 months. Toy breeds finish growing fastest of all dogs — most of their gain happens before six months.
When do Cavachons stop growing?
Most Cavachons reach their full adult height and weight by about 9 months. Growth is fastest before 3.2 months, then slows steadily — by 6.7 months your puppy will be about 90% of its final size.
How much should a Cavachon puppy weigh at 4 months?
A typical 4-month-old Cavachon weighs roughly 6–12 lb, about 64% of its adult weight. Use the calculator above with your puppy’s exact weight for a personalized estimate — individual dogs vary.
