What Is A F1, F1B, F2, F3 Doodle? (With Illustrations)

Doodles are a new modern hybrid dog and when I first started researching I was overwhelmed by all these confusing terminologies.

Here is what I learned.

What Is An F1 Doodle And The P-Generation?

The P-Generation is the purebred parent generation of Doodles.

The F1 generation is the first generation of the mix of two purebred breeds, most often with a Poodle and another breed.

The Poodle is often used to pass on its curly non-shedding coat qualities to other breeds because more and more people are developing allergies to dogs that shed.

What does F1B mean?

The Aussiedoodle is a mix of the Australian Shepherd and a Poodle. The first generation of this mix is called the F1.

The first generation is a 50/50 hybrid.

The F1B Aussiedoodle is a second-generation Aussiedoodle and also called a backcross as the doodle is bred back with a Poodle. The parents are a first-generation Aussiedoodle and a Poodle, meaning that the second generation is 75% Poodle and 25% Australian Shepherd.

Do F1 or F1B Doodles Shed?

The F1 (first-generation) Doodle is a hybrid of the two purebred parents. Therefore the resulting doodle is 50% of either parent and as the poodle parent doesn’t shed at all (basically) and the Australian Shepherd parent does, the shedding potential is somewhere in between.

There is a chance that their offspring won’t shed at all or shed a little. Most likely (like in my case) they’ll land somewhere in between and have a somewhat wavy coat which sheds less than the Shepherd would.

My Aussiedoodle, Teddy

The F1B Aussiedoodle is 75% Poodle and 25% Australian Shepherd.

Poodles don’t shed (at all basically) because they have a curly coat that catches any shedding hair. They also don’t have fur that can shed seasonally but instead have hair (like humans have) and require occasional haircuts.

The potential for an F1B Aussiedoodle to shed is far less and basically non-existent if they have a very curly coat, like their Poodle parent.

If shedding is your concern I would recommend that you get a second-generation Doodle which has far less shedding.

What Is An F2 Doodle?

An F2 Doodle is the second generation of a Doodle and a mix of two first-generation Doodles.

Do F2 Doodles Shed?

The F2 Doodles are really a mystery package. You never know what you are getting as the Poodle to Shepherd ratio can be anywhere between zero and a hundred.

In the first generation of doodles, you know that they are 50/50 of either parent but as soon as you breed two first-generation doodles together, you get chaos.

You can take this to your advantage though.

If you are looking for a hybrid that has features of the Australian Shepherd, Labrador or Golden Retriever but need a dog that doesn’t shed at all, this is where you need to look.

Go look at a litter that still has multiple puppies available and look for the curliest ones you can find.

These are the ones you want as they are almost guaranteed to not shed at all. They might be 90% Poodle and have extreme curls but still have the personality or color scheme of the other parent.

Don’t be fooled, there can still be puppies in an F2 litter that shed but they have the potential to be more than 50% Poodle (which the first generation doesn’t)!

What Does F2B Mean?

The F2B Doodle is a hybrid of an F1B Aussiedoodle and first-generation Aussiedoodle.

F3 And Multi-Generation Hybrid

The F3 Doodle is the third generation of doodles, created with two F2 Doodle parents. Anything beyond the F3 or even F4 generation is considered a Multi-Generation Hybrid.

Do Hybrid Dogs Have Papers?

Hybrid dogs like Aussiedoodles, Labradoodles and Goldendoodles rarely have papers.

Normally, only the purebred dogs get papers and are registered in the American Kennel Club (AKC) or the British version, Kennel Club (KC). It is possible to register a hybrid dog in a newer registry but it’s rare.

Registered purebred dogs usually have a higher value and are allowed to partake in dog shows. Their offspring will most likely also be more expensive than unregistered.

It could be possible that the parents of the doodle have papers when they are purebred dogs.
