Goldendoodle Sizes

Petite range: Height: below 14 inches, typically 25 lbs. or less

Miniature range: Height: over 14 but under 17 inches (35cm to 42cm) at wither, typically 26-35 lbs.

Medium range: Height: over 17 but under 21 inches (43cm to 52cm) at wither, typically 36-50 lbs.

Standard range: Height: over 21 inches (53cm to 63cm) at wither, typically 51 or more lbs.

Final size category of a dog will be determined at adulthood and is measured at the withers. Please be aware that the estimated size of a puppy by a breeder is an educated guess; therefore, a puppy’s final size may vary somewhat from a breeder’s initial calculation. 

Coats and Colors

COLORS

Goldendoodles come in a rainbow of colors. The Golden Retriever ancestry brings only shades of cream, apricot and red to the breed. These colors are all controlled by the same gene, with the shade of color determined by the intensity of the inherited gene. While the Poodle heritage also includes creams, apricots, and reds; Poodles alone lend the black, chocolate (dark brown), silver and gray coloring (and the color patterns) to the Goldendoodle coat.

For even more variety, there are patterns of these colors found in the Goldendoodle, including parti, merle, phantom, and brindle. A parti colored Goldendoodle is at least 50% white, with solid patches of any other color. A solid color Goldendoodle with white markings that cover less than 50% of the body are known by several names: abstract, mismarks, or chrome.  Merle is a varied coat pattern. While a beautiful color, the merle gene can cause blindness and deafness if two parents carrying the merle gene are bred together, so merles should be bred only by very knowledgeable breeders who test for the merle gene and understand the genetics involved.  Phantom’s have a specific pattern of markings on a solid background above each eye, on the sides of the muzzle, chest, inside the legs, and under the tail. Brindle patterns appear as stripes, the color and the width vary with each dog.

COAT TEXTURE AND APPEARANCE

The primary concerns for any dog breeder must be health, temperament and conformation; but who can deny that the outward appearance of a Goldendoodle pulls at our heartstrings! With careful breeding, breeders can now produce litters with predictable coat types and shedding propensities.

One of the things that many people find attractive about the Goldendoodle is the low shedding and hypo-allergenic qualities of the coat, and the adorable ragamuffin look of the Goldendoodle. DNA research now gives us information about how coat genes affect the “look” of a Goldendoodle. No longer do you need to rely on the generation of a Goldendoodle to determine appearance or shedding intensity!

Length (FGF5 gene)

The coat length gene determines whether a dog has a long (L) or short (S) coat. Although long coats are recessive, because both Goldendoodle parent breeds are long-coated, all Goldendoodles carry two genes for long coat (L/L). Since short coat is dominant, if a dog carries a gene for the short gene (S/L) their coat would be short. This is why some Labradoodles have short coats in the early generations, whereas Goldendoodles do not.

Curl (KRT71 gene)

Goldendoodles can be curly, wavy, or straight.

A Goldendoodle’s coat can have different amounts of curl. They inherit their number of curl genes from their parents.  Typically a Goldendoodle that is curly is +/+ for curl, a flat or straight dog is -/- for curl, a dog with a wavy or loose curl coat is +/-.   Since a wavy coated Goldendoodle can carry a curl gene (+/-), two wavy Goldendoodles bred together can produce all three coat types – curly, wavy, and straight. If a breeder tests the parent dogs for the curl gene, they can better predict the appearance of their puppies.

SHEDDING AND FURNISHINGS

What are Furnishings and Improper coat (gene RSP02)?

Furnishings are arguably one of the first things you’ll notice about a dog that helps you identify it as a characteristic “Doodle.” Furnishings are the longer facial hair, including eyebrows, mustache and beard, found on most Goldendoodles.

Golden Retrievers have an “open face,” that is, short facial hair, sometimes also known as incorrect coat.

Even more interestingly, genetic technology has taught us that furnishings are what confer the low- to non-shedding coats on our Goldendoodles that help make them such optimal family dogs. Earlier thinking was that curl and a gene aptly named the “shedding” gene were also important, but more recent findings tell us that neither is relevant to the likelihood of furnished dogs to shed. 

Back in the “old days,” breeders had to use generations (F1, F1b, etc) to help make an educated guess as to whether two dogs would produce puppies with or without furnishings. Based on Mendelian genetics, this educated guess was often just that—a guess about the odds. This is when the use of notations like F1 and F1b came about and what has caused many people to think they need to know the generation to guess about furnishings.

In the recent past, new commercially available tests have been developed that allow us to genetically test our parent dogs for furnishing genes (and other coat genes as well, such as curl) so we can better predict coat type in puppies. This is much, much more accurate and dependable than the old Mendelian filial F1, F1b, etc. type labeling. We strongly recommend that if shedding or the furnished “look” is important to you that you find a breeder who performs genetic testing and doesn’t leave the presence of this gene to the vagaries of guessing.

The common abbreviation for the furnishing gene is an “F” and for an improper coat (no furnishings gene) the abbreviation is often either “IC” (incorrect coat) or “f.” So there are three possibilities for this gene: FF, Ff (or F IC), or ff (or IC IC).

The gene responsible for furnishings is dominant; so by testing the parent dogs DNA, it can be determined if a breed pair will produce puppies that all have furnishings, or if there will be some puppies with an incorrect (or Golden Retriever like) coat. Dogs with one copy of the furnishings gene (Ff or F IC) are lower shedding than dogs without furnishings. Dogs with two copies of furnishing genes (FF) are typically non-shedding.

Although most prefer the Goldendoodles with furnishings, aka a “Doodley” coat, there is a market for Goldendoodles who look more like Golden Retrievers, but sometimes lower shedding than a Golden Retriever.  If you have a family with allergies, a Goldendoodle with an incorrect coat is not the best match for you.

By testing the parent dogs of Multigenerational (“multigen”) Goldendoodles, your breeder can be sure not to breed parents that will produce puppies with incorrect coats (without furnishings) unintentionally.
