There are currently no size classifications for the Goldendoodle. It is difficult for a hybrid litter to "breed true"; that is, it is difficult to know exactly what size a Goldendoodle or Labradoodle will grow to as an adult, regardless of parental size. However, Goldendoodles are usually described as either Standard or Mini. A standard Goldendoodle is the result of crossbreeding with a standard-sized Poodle. A mini Goldendoodle is the result of crossbreeding with a miniature Poodle, although some mini Goldendoodles grow beyond their intended size. The Goldendoodle can come in many different colors, depending on the poodle genes passed onto the pup. Truly golden Goldendoodles are more popular than other colors, and are more expensive. However, Goldendoodles can be tan, black,silver, or a mix. Black Goldendoodles are fairly common and less expensive than golden offspring. A mix of colors can come from the same litter.
