What size is a full-grown Cavachon?

Both Cavalier King Charles Spaniels and Bichon Frise are compact breeds, so it’s no surprise that Cavachons are small, too. A full-grown Cavachon weighs between 10 and 20 pounds and stands 9 to 11 inches tall. Mini Cavachon dogs are even smaller and weigh as little as five pounds once fully grown. Adult Cavachon will reach their full size by the time they’re about a year old.
