A straight hair Goldendoodle is a Goldendoodle that has, well, straight hair! These Goldendoodles inherit their straight hair from the Golden Retriever side of their family tree. They are sometimes called “flat coat Goldendoodles” because of their lack of curls.

In this article, we’ll explore the unique characteristics of straight hair Goldendoodles, their grooming needs, shedding tendencies, and why they might be the perfect fit for your family.

Why Do Some Goldendoodles Have A Flat Coat?

Goldendoodles can have flat coats due to their genetic makeup. They inherit genes from both their Golden Retriever and Poodle parents, and if they receive two copies of the recessive gene for straight hair, their coat will be flat.

Additionally, some breeders specifically aim for flat-coated Goldendoodles because they tend to shed less. While it’s harder to predict coat type in earlier generations of Goldendoodles, the presence of a specific gene called the “improper coat” gene strongly influences a flat coat appearance.

We’ll discuss these factors and more in detail below.

Genetics

The Goldendoodle is a cross between a Poodle and a Golden Retriever. Puppies produced from this designer crossbreed can take on characteristics from both parents, although no two puppies are identical. Even pups from the same litter can appear totally different, depending on which parent’s genes are dominant in each puppy.

So, some F1 Goldendoodles might develop the curly coat of the Poodle parent, whereas others could have a flat, straight coat like a Golden Retriever. 

Generations

The coat type of every puppy will also be influenced by what generation of crossbreed it is.

F1 or first-generation puppies have one purebred Poodle parent and one purebred Golden Retriever parent. That means that the puppies will get half of their genetic makeup from each parent. So, basically, an F1 Goldendoodle is 50% Golden Retriever and 50% Poodle.

However, an F1B Goldendoodle has one purebred Poodle parent and one F1 Goldendoodle parent. So, the puppies are 75% Poodle and 25% Golden Retriever. That means F1B puppies are more likely to have a curly coat than F1 puppies.

Generally, F1B puppies are the most popular Goldendoodle variation, as they have the cute teddy bear looks that people love, and they have a very low-shedding coat. 

Coat Changes

As a Goldendoodle puppy matures, his coat often changes. For example, the color of the coat might fade and become lighter, or the hair can get straighter or curlier as the puppy grows.

That’s one of the appealing things about Goldendoodles; you never quite know what you’re going to end up with!

Are Flat-Coated Goldendoodles Rare?

So, straight hair Goldendoodles rarely occur in F1B and F1 puppies. However, they are regularly found in F2, and F2B litters. 

Most people looking for a Goldendoodle puppy want the typical Doodle curly-coated look, so for that reason, flat-coated Doodles are not seen as commonly. In fact, if you come across an adult Doodle with a flat coat, you probably wouldn’t even know that it was a Goldendoodle at all! That’s why these dogs are often considered to be rarer than they are in reality.

How Can You Tell What Type Of Coat Your Doodle Will Have?

The best way to work out what kind of coat your puppy will have at maturity is to take a look at the hair around his mouth.

  • If your pup is going to develop a curly coat, he will have tight curls around his mouth.
  • Puppies with wavy coats will have wavy hair around their mouth.
  • Puppies that are going to grow a straight coat will have short, straight hair around their mouth.

Consider How Your Dog Was Bred

As previously mentioned, your dog’s coat type is dependent on genetics. So, let’s take a simplified look at that.

We’ll refer to the Retriever coat gene as the “N” gene. The “N” gene gives the dog a smooth face without a mustache or beard and a shedding, silky coat. However, Poodles have an “F” coat gene, where “F” stands for furnishings. 

If you cross a Poodle with a Golden Retriever, you produce F1 Goldendoodle puppies. Every puppy will take one coat gene from either parent, giving the puppy a genetic coat code of F/N. So, all the puppies will have the characteristic Doodle furnishings. However, when it comes to F2 crossbreeds, coat type is a game of chance. Some puppies will take one “F” gene and one “N” gene, whereas some (around 25%) will take two “F” genes, producing a Poodle coat. Others will inherit two “N” genes, resulting in a puppy with a flat coat.

Breeding Practices

Some Goldendoodle breeders breed F1B Doodles, which is an F1 dog bred with a purebred Poodle to avoid that lottery. 

Alternatively, some breeders have their F2 breeding dogs’ DNA tested for coat type, using only dogs that have inherited two copies of the “F” gene. On the other hand, some breeders are quite happy to produce flat-coated Goldendoodle puppies.

What Are the Downsides of a Flat Coat Goldendoodle?

The main downside of flat-coat Goldendoodles is their increased shedding compared to curly or wavy variations. This shedding makes them less hypoallergenic, as more dander (which triggers allergies) is spread.

Despite this, they generally still shed less than purebred Golden Retrievers. It’s important to note that some breeders use genetic testing to ensure they breed for specific coat types, and a DNA test can confirm your puppy’s coat tendencies.

Shedding

The main downside of a flat coat Goldendoodle is that these dogs tend to shed much more than their curly-coated counterparts.

That’s because the straight hair Doodle’s genetic makeup contains less Poodle DNA, making it more prone to shedding. That said, Goldendoodles still shed less than purebred Golden Retrievers.

Less Hypoallergenic

As you would expect, flat coat Goldendoodles are typically less hypoallergenic than curly or wavy coats, simply because they shed more.

However, it’s not the actual hair that causes an allergic reaction in people who are sensitive to animal fur. The allergy is caused by the dander, a combination of shed skin cells and saliva. Dogs that shed a lot of hair also tend to drop more dander than those that don’t shed as much. 

Why Should You Get A Straight Coat Goldendoodle?

Most people want a Teddy Bear Goldendoodle for their looks. However, if you don’t want your dog to look like a Poodle, you might prefer a straight coat Doodle. Basically, that’s down to personal preference.

Also, if you have a curly coat Goldendoodle, your dog’s coat can be prone to matting. Most people have their Doodles clipped every few weeks to keep the coat short and mat-free, which adds to the expense of keeping the dog. However, since straight-coated dogs shed more, you’ll still need to brush your Goldendoodle every day or so to keep the coat in good condition and get rid of loose hair that would otherwise finish up on your floors and furniture.

Genetic Testing For A Straight Coat Goldendoodle

Many breeders have their stud dogs genetically tested to determine whether the dogs will produce straight, wavy, or curly-coated puppies. 

The Cu locus gene, also known as the KRT71 gene, decides what coat type the puppies will have. Usually, the less Cu locus the puppy has, the straighter its coat will be. As Goldendoodles are usually created from many generations of Standard Poodles and Golden Retrievers, it’s likely that their coats will have a recessive Cu locus gene or be wavy.

If you want to know what kind of coat your puppy will have, you can ask your veterinarian to perform a reliable DNA test. 

What’s the Grooming Difference Between Curly and Straight Coat Goldendoodles?

Curly coat Goldendoodles need much more intensive grooming than their straight-coated counterparts. They require regular, frequent brushing to prevent mats and tangles, along with professional grooming sessions every 6-8 weeks. Straight-coated Goldendoodles still need regular brushing to manage shedding, but it’s less frequent and they generally don’t require professional grooming unless you prefer a trimmed look.

Wavy Coat

The wavy or shaggy coat is the most commonly seen kind of Goldendoodle coat. The coat has a shaggy appearance or falls in soft waves and takes the least maintenance of the three coat types.

To keep the coat tangle-free and in good health, you need to brush your dog regularly to get rid of mats and loose hair. However, Goldendoodles with a wavy coat are usually low to non-shedding.

Curly Coat

If your puppy takes mostly after the Poodle parent, he’s likely to have a tight, curly coat. That’s not to say that these are short-haired dogs! The tightness and length of the curls vary, depending on the puppy’s parents. So, you can have long, loose barrel ringlets or tight, kinky Poodle curls. 

Goldendoodles with a curly coat need regular grooming to prevent the hair from matting. That’s why many Doodle owners prefer to have their pets shaved close to create a maintenance-free style.

Curly coat Doodles are usually F1B, and the coat type is the second most commonly seen. These dogs are very popular with people who have pet allergies since the coat barely sheds at all.

Straight Coats

The straight-coated Goldendoodle is often mistaken for a Golden Retriever. You generally see the flat or straight coat in F2B and F2 generation Goldendoodles and very rarely in F1B and F1 dogs.

Straight-coated dogs don’t have the furnishings of their curly-coated cousins, but they do tend to shed quite a lot more. The straight coat is straightforward to maintain and doesn’t tend to mat, making this coat type very popular with owners who don’t want to spend a lot of time grooming their dog. 

You’ll need to brush your dog with a slicker or pin brush a few times each week and wipe him over with a grooming mitt to keep the coat looking good. Unlike curly-coated dogs, brambles and leaves are much less likely to get tangled in the dog’s coat. Also, these dogs don’t have hairy feet that need inspecting and combing every day. Never have a straight coat Goldendoodle shaved or clipped.

Flat coat Goldendoodles need a bath only when they begin to develop that unpleasant doggy odor that most pups get after a while. That said, if your pup decides to roll in something unspeakably nasty, a bath will be in order!

Are Flat-Coat Goldendoodles Hypoallergenic?

Flat-Coat Goldendoodles aren’t considered truly hypoallergenic. While the Poodle side of their genetics can contribute to reduced shedding, all dogs produce dander and saliva that contain allergens.

Flat-Coat Goldendoodles do shed, even if it’s less than curly-haired Goldendoodles, and this shedding contributes to the spread of allergens. Individual dogs can vary in the amount of allergens they produce, so if you have severe allergies, it’s crucial to consult with an allergist and spend time with any potential dog before deciding to bring them home.

In Conclusion

While the curly and wavy-haired Goldendoodles are the most recognizable, flat-coated Doodles offer a unique charm and distinct advantages. If you’re looking for a Goldendoodle with less shedding, a more Golden Retriever-like appearance, and slightly easier grooming, the flat-coat variation might be the perfect fit!

Remember, coat type is just one factor when choosing the perfect Doodle companion.  Consider your lifestyle, allergies, and grooming preferences alongside temperament and personality when selecting your new furry friend.

  1. My goldendoodle Jude is a straight coat. Both his parents are F1b. He was the only one in a litter of four who came out straight coat. He has no hair around his eyes or mouth. It is all smooth. He lost his puppy fur but he is getting some wavy curl on his back. We are excited to see what he will end up like.

    • Joni, mine is the same. He has a few waves, but basically straight. He does shed a bit. Mine is 10 months and just 14lbs. He is a mini and I think he will remain very small. He looks like a very mini golden with no poodle qualities.
      He has been such a wonderful addition to our family!
