Straight hair Goldendoodles, also known as flat coat Goldendoodles, are becoming an increasingly popular dog type because people like the straight hair that resembles a Golden Retriever and makes them look more like a teddy bear. In addition, dog owners also wish to get a hypoallergenic, friendly temperament, and non-shedding dog breed. This makes a straight hair Goldendoodle the ultimate choice for a dog.
If you’re looking for a straight hair Goldendoodle, we recommend that you look at either a F1 Generation Goldendoodle or F2 Generation Goldendoodle as these generations contain 50% Golden Retriever genes. This maximizes your chances of selecting a Goldendoodle that will have a straight coat.
How does a Goldendoodle get a straight coat?
There is a dog gene called Cu locus (AKA Curly Coat Gene) which determines if your dog will have curly hair. The absence of Cu locus means that you will have a straight hair Goldendoodle. The Cu locus gene typically comes from the Standard Poodle because they have the extremely curly coat. Cu locus prevents keratin from binding together structural components which results in a curly coat. The means that if you have keratin from your genetic structure than your Goldendoodle will have a straight or flat coat. You can get a DNA test to determine if your dog has the presence of this gene.
In reality, most Goldendoodles will have a wavy coat and won’t actually have straight or flat coats. This is because they usually get a mix of the Cu Locus gene since they are a hybrid dog breed of Golden Retriever and Poodle.
Which generation of Goldendoodle has a Straight Coat?
We’ve written an extremely in-depth article of the Best Goldendoodle Generations. This article gives all the in-depth information on what the terminology of a Goldendoodle offspring means. In general, F stands filial and means that it is a hybrid dog, the # means the generation of dog, and the B means back cross.
If you’re looking for a flat coat Goldendoodle, then you typically want a 1st generation Goldendoodle or F1 Goldendoodle. In addition, there is also a high chance of getting a straight hair Goldendoodle if they are a F2 Goldendoodle or 2nd generation Goldendoodle. In general, you want to pick a Goldendoodle generation that is 50% Golden Retriever and 50% Poodle in order to maximize your chances of a straight hair Goldendoodle.
Since most Goldendoodle’s are back crossed bred with a Poodle in order to become more hypoallergenic and non-shedding, you don’t want any back crossed Goldendoodle’s. In addition, this means that the higher the number of generations and the more B’s in the name the curlier the coat will be. If you want a straight hair Goldendoodle than you want more Golden Retriever genetics.
As a quick recap, here are the most popular generations of Goldendoodle and what percent the genetics should be:
- F1 Goldendoodle: 50% Poodle & 50% Golden Retriever. The highest chance of straight coat Goldendoodle.
- F1B Goldendoodle: 75% Poodle & 25% Golden Retriever. These coats are typically wavy to curly.
- F1BB Goldendoodle: 87.5% Poodle & 12.5% Golden Retriever. These coats are typically curly.
- F2 Goldendoodle: 50% Poodle & 50% Golden Retriever. The highest chance of straight coat Goldendoodle.
- F2B Goldendoodle: 62.5% Poodle & 37.5% Golden Retriever. These coats are typically wavy to curly.
- F2BB Goldendoodle: 81.25% Poodle & 18.75% Golden Retriever. These coats are typically curly.
- F3 Goldendoodle or Multi-generation Goldendoodle: Several generations of Goldendoodle breeding typically back cross-breeding to the Standard Poodle. These coats are typically wavy to curly.
In general, try to get a Goldendoodle that is at least 50% Golden Retriever in order to maximize your chances of getting a straight coat. Otherwise, you can try to find a breeder that back crosses Goldendoodles with Golden Retrievers (this is rare).
Downsides of a Flat Coat Goldendoodle
Getting a straight or flat coat Goldendoodle does have some downsides compared to a typical wavy to curly haired Goldendoodle.
- Flat coat Goldendoodles tend to shed a lot more than wavy or curly haired Goldendoodles. This is because flatter coats contain less Poodle genetics which makes the dog have a curlier coat. Be prepared to have hair that sheds on your floor. However, a flat coat Goldendoodle tends to shed significantly less than their Golden Retriever counterparts.
- Straight Coat Goldendoodles tend to be less hypoallergenic. Due to having more Golden Retriever genetics and less Poodle genetics, straight coat Goldendoodles will be less hypoallergenic. The hypoallergenic feature comes from the curly coat and non-shedding features. Hypoallergenic features are created because curly dog hair doesn’t allow dander and other protein allergens to stick to their dogs skin.
Please note that curliness generally correlates to non shedding and hypoallergenic features. This is not always the case though and is more likely to correlate to your dog’s genes. Specifically, you’ll want to look at the Furnishing Gene and Shedding Locus Gene to get a better understanding of if your dog is non shedding and hypoallergenic. We recommend getting a DNA test on your dog if you want to figure out their genetic structure.
Why should you get a straight coat Goldendoodle?
Getting a flat coat Goldendoodle vs. curly coat Goldendoodle is a tough decision. Primarily, people get a straight coat Goldendoodle because of their looks. Typically, dog owners want a Goldendoodle that looks like less like a Poodle and more like a Golden Retriever. In addition, straight or flat coat Goldendoodles tend to look “cuter” and more like a teddy bear. At the end of the day, it’s all personal preference.
In addition, you will generally have to groom a straight coat Goldendoodle less than a curly coat Goldendoodle. Since a straight coat Goldendoodle sheds more hair there is less upkeep with hair cuts and regular grooming. Additionally, your dog is less likely to develop mattes if you don’t brush them regularly. Shaving a Goldendoodle takes a lot of work, so this a huge upside.
Genetic Testing for a Straight Coat Goldendoodle?
Genetic testing of the Cu locus gene, also known as KRT71 gene, will determine whether or your not Goldendoodle will have a straight coat, wavy coat, or curly coat. In general, the less Cu locus gene your dog has the more straight their coat will be. Since Goldendoodles are typically multiple generations of Golden Retriever and Standard Poodle, typically back bred with the Standard Poodle, it’s more likely that their coat will be wavy or at least have a recessive Cu Locus gene.
You can consult your veterinarian for a reliable DNA test of your dog to determine what kind of coat they will have. In general, you can usually determine whether or not your Goldendoodle will have a straight coat or curly coat based on their puppy coat. Typically, Goldendoodle litters will have a mix of straight coats, wavy coats, and curly coats. Once they use their puppy hair, typically the adult hair doesn’t change structure type.
Frequently Asked Questions
How can I tell if my Goldendoodle will have straight hair?
Straight-haired Goldendoodles are very low maintenance and easy to groom. However, they shed much more hair than curly or wavy-haired Goldendoodles. They are not the best option for people who suffer from allergies because of how much they shed.
You can avoid them shedding too much by brushing their coats on a daily basis. But how will you know whether your Goldendoodle is going to have straight hair or not?
The snout of your Goldendoodle puppy is the best way to determine which coat type they’re likely to have. Straight-haired Goldendoodle puppies will often have short and neat hair around the snout. This is compared to curly-haired Goldendoodle puppies who tend to have mustaches or beard-like patterns around their snout.
If your Goldendoodle puppy is other than a first-generation dog, you should look to the parents to see what their coat looks like. If the parents have straight hair, it’s likely that their offspring will have the same type of coat.
Unfortunately, there is no clear-cut way to determine whether your Goldendoodle will have straight hair or not. The only way to really find out is to wait for them to grow up and mature into their final coat types!
Can Double Doodles have straight hair?
A Double Doodle is a dog breed mixed between a Goldendoodle and a Labradoodle. As both of these dogs are already a mixed breed between other dogs and Poodles, they can both have straight, wavy, or curly coats.
This means that Double Doodles can also have straight coats, although this is much less commonly seen than Double Doodles with wavy or curly-haired coats.
Any dog that has Poodle lineage will often be much more likely to have a wavy or curly coat than a straight-haired coat. While you can get straight-haired Double Doodles, they’re uncommonly seen among owners and breeders.
Again, you won’t know for sure what type of coat type your Double Doodle has until they reach an older age. The puppies will all have coats that are too short to know whether they will be curly or not for sure.
How rare is a flat coat Goldendoodle?
Flat coats come from Retrievers who often have black or liver-colored coats. Their fur is medium-length, thick, and sleek. The hair is straight without any curls and lies flat against the dog’s body.
As Goldendoodles have a lineage of Golden Retrievers, there is the question of whether a Goldendoodle can have a flat coat or not.
With F1 or F1b Goldendoodles, flat coats are very rare. In fact, it is only possible for this generation of Goldendoodles to be flat-coated if the Poodle parent carries only one copy of the ‘F’ gene. If they’re carrying more than this, you won’t get an F1 or F1b Goldendoodle with a flat coat.
However, F2 and F2b Goldendoodles are much more likely to have flat coats. In these litters, flat coats are much more commonly seen.
Many people think that flat-coated Goldendoodles are much rarer than they are because many people don’t know what a flat coat is unless they were to talk to a breeder. Many people might adopt a flat-coated Goldendoodle without ever knowing that it is a Goldendoodle!
When purchasing a Goldendoodle, most people want the traditional curly-coated look. For this reason, flat-coated Goldendoodles are not bred as much or seen among breeder’s portfolios.
So, they are a rarer type of Goldendoodle because they are not bred as much, but this doesn’t mean that they are necessarily rare. You might have seen a flat-coated Goldendoodle without even realizing it.
