F1 vs F1B Aussiedoodle: 5 Key Differences
F1 vs F1B Aussiedoodle: 5 Key Differences (F1BB, Reverse F1B, F2, F2B, Multigen & Ultra Aussiedoodles Explained)
If you’re comparing an F1 vs F1B Aussiedoodle, you’re probably trying to figure out one thing: which is the best fit for your home and lifestyle.
Many families researching Aussiedoodles quickly become overwhelmed by all the different doodle generation terms. Understanding these generations is important because they can affect shedding, coat type, allergy friendliness, predictability, breed percentage, and overall appearance.
In this guide, we’ll break down the key differences between F1, F1B, Reverse F1B, F1BB, F2, F2B, and multigen Aussiedoodles (or any type of doodle) so you can confidently choose the right fit.
Understanding Aussiedoodle Generations
When breeders or sites start throwing out random letters and numbers in front of Aussiedoodles to describe their generations it can be very confusing. The letter 'F' stands for filial generation which is a generation of offspring in a breeding program following the pairing of two different breeds of dogs. Different generations of aussiedoodles will create different coat types, shedding tendencies and predictability outcomes.
Quick Answer: F1 vs F1B Aussiedoodle
The main difference between an F1 vs F1B Aussiedoodle is the Poodle percentage, shedding level, and coat predictability. F1 Aussiedoodles are 50% Poodle and 50% Australian Shepherd, while F1B Aussiedoodles are approximately 75% Poodle and usually have lower shedding and curlier coats.
F1 Aussiedoodle
The F1 Aussiedoodle is 50% Australian Shepherd (or base breed) and 50% Poodle. This generation has moderate to low shedding - I always say with an F1 Aussiedoodle you are not going to find hair all over your house, but you may find a small amount of hair on your clothes after cuddling the dog, on the furniture, etc. This can be greatly reduced if you brush your dog out regularly or if they have a shorter haircut. If you keep their coat longer you will notice more shedding & it is important to brush regularly to keep the shedding under control. The F1 Generation typically has wavy or straighter coats (but this is largely determined by the curl coat genetics of the parent dog - specifically the poodle). They are pretty predictable when it comes to coat outcomes. There isn't usually a ton of variety between puppies in shedding or coat texture since you are breeding a shedding dog (Australian Shepherd) to a non-shedding dog (Poodle). However, if the poodle doesn't have two copies for curly coat texture, non-shedding, or furnishings you will see different looks in the puppies as they grow. The F1 Generation is not always the most ideal for severe allergies. If you have very mild or moderate allergies (specifically to shedding dogs), the F1 may be an acceptable generation. Usually I recommend F1B generation at a minimum if you have any sort of allergies. This generation is great for families wanting a balanced mix of both breeds (The Austrlian Shepherd and the Poodle), and also a high percentage (50%) of the base breed (Aussie) in your doodle, while also reeping the benefits of significantly less shedding than you would find in the Australian Shepherd.
F1B Aussiedoodle
The F1B Aussiedoodle is approximately 75% Poodle and 25% Australian Shepherd. You get this generation when you take a F1 Aussiedoodle and breed it back to a full blood Poodle. This generation is very low shedding, it is nearly non-shedding, but you will definitely get hair (like us humans) when you brush out the hair, but will most likely not find hair on your clothes, furniture or floating around the house. The coat texture of the F1B generation varies from straight/wavy to curly teddy bear coats. You usually will get roughly half the puppies with straighter to wavy coats and the other half will be curlier, but this all depends on the curl genetics of the poodle and the coat genetics of the F1 Aussiedoodle parent. The non-shedding is more predictable in this generation compared to the F1 generation, but when it comes to coat texture, there is typically more of a variety. This generation is great for families with allergy sensitivities, those wanting a dog that is very minimal to nearly no shedding while also getting some of the Australian Shepherd base breed characteristics.
Reverse F1B Aussiedoodle
The Reverse F1B Aussiedoodle is not nearly as common as the regualar F1B, but I feel it needs mentioned. This generation is 75% Australian Shepherd and 25% Poodle. You get this generation by breeding a F1 Aussiedoodle back to an Austrlian Shepherd (instead of the poodle). In my opinion, there isn't a ton of reasons to do this cross, unless the breeder is hoping to keep a specific puppy back in their program that has a higher Australian Shepherd breed percentage. This generation has straight to light wavy coat textures and half of the litter will be non-furnished (where the face will look more like a traditional Aussie - ** see pic below**) and the other half will have the F1 look. These puppies will definitely shed more, you really get a mixed bag in terms of furnishings and shedding level when you breed this generation. This generation is not ideal for allergy sensitive homes. This generation is great for families that want a high percentage of Australian Shepherd, but potentially lighter shedding than a traditional Australian Shepherd.
F1BB Aussiedoodle
The F1BB Aussiedoodle generation is also not a super common generation, but you do see it from time to time. This is when you take a traditional F1B Aussiedoodle and breed it back to a poodle. The F1BB Aussiedoodles are approximately 87.5% Poodle and 12.5% Australian Shepherd, meaning they are nearly all poodle, with just a slight influence of Australian Shepherd. This generation is pretty predictable and typically has curly coats from their high percentage of poodle, which causes them to be extremely low shedding and makes them excellent for those with severe pet allergies. Due to this generations curlier coats, they do require higher grooming maintenance as the coats tend to mat easier and need brushed out more frequently (daily) in order to keep it from getting tangled. This generation is great for those who are looking for doodle and they have severe allergies, do not want any shedding but still prefer to have a little influence from the Australian Shepherd in the their dog.
F2 Aussiedoodle
The F2 Aussiedoodle is when you take an F1 Aussiedoodle and breed it to another F1 Aussiedoodle. This generation is theoretically 50% Australian Shepherd and 50% Poodle, however the overall consistency and predictability of this generation is very low. You can get puppies that look like Aussies, some that look like F1 Aussiedoodles and some that also have very curly coats and look more like a poodle. Because the the extreme variations in coat textures, this generation can vary a lot when it comes to shedding, They can be very allergy friendly or they can also be extremely bad for allergies (all depending on the puppy, its coat and its shedding tendencies). The grooming maintenance from this generation varies a ton as well, the Australian Shepherd looking puppies will need little to no grooming maintenance, the F1 looking puppies will need minimal grooming and the curly coated puppies will need high grooming maintenance. This generation is good for those looking for a high Australian Shepherd percentage, but also looking for a specific and unique coat texture (either super curly or the Australian Shepherd look). Finding a breeder who does coat testing or is experienced may be beneficial with this generation so you have a better idea on what type of puppy you will be getting.
F2B Aussiedoodle
The F2B Aussiedoodle is most often produced from one F1 parent bred to an F1B parent, producing puppies that are 62.5% Poodle and 37.5% Australian Shepherd. This generation can however also be produced by breeding an F2 parent back to a poodle (this variation is less common and is actually 75% Poodle and 25% Aussie like the F1B generation). For the sake of keeping this article simple, we are going to focus on the first combination where the puppies are 62.5% poodle and 37.5% Australian Shepherd. This generation creates puppies with incredibly soft wavy and fleecy coats, consistency of the coats can be fine tuned and predicted based on the coat types of the parents, but typically is a loose wavy texture. These puppies are very low shedding with balanced texture throughout the litter, making them a great option for those with mild allergies. This generation is good for those looking for a super soft coated doodle with very low shedding, a higher percentage of Australian Shepherd and usually pretty consistent coat textures.
Multigen Aussiedoodle
The Multigenerational Aussiedoodles can vary alot in breed percentage and also what the parents are. Some people classify F2B generation as multigens, but for the sake of bringing clarity to this article I decided to separate it out. A few common Multigen Pairings are:
- F1B x F1B
- F2B x F1B
- F2B x F2B
- F1 x F2B
- F2 x F1B
- F1 x F1BB
- Reverse F1B x F1B
Multigen is just short for Multigenerational, which means that there are several generations bred together to create the Multigen. The Multigen Aussiedoodles will always have both parents that are Aussiedoodles of some generation (no Australian Shepherd or Poodle parents). It is important to work with a credible and experienced breeder when it comes to Multigen Doodles as they should be able to help you understand what generations are going into the makeup of your puppy and can help explain the coat textures expected, the shedding level and how they will be for allergies. When bred intentionally, the Multigens can end up being a higher percentage of the base breed (Australian Shepherd) than the poodle, but be very minimal shed and also great for allergies. The Multigen generation has the potential to be very good for those wanting a super consistent puppy with a straighter to wavy soft/fleecy coat, very minimal shedding and great for allergies, but it is important to understand that this generation can vary greatly depending on the parent dogs that are used in the pairing.
Ultra Aussiedoodle
Ultra Aussiedoodles are when you have a greater than 50% percentage of Australian Shepherd. The Reverse F1B would technically be an Ultra Aussiedoodle (since it is 75% Aussie), but you will more commonly see them with a traditional F1B Aussiedoodle bred to an Australian Shepherd, creating an Ultra Aussiedoodle which is 62.5% Australian Shepherd and 37.5% Poodle. These puppies will be similar in coat texture to the F1 Generation, but will just have a higher percentage of the base breed in them (Australian Shepherd). The Ultras could also be produced by breeding really anything (the F1BB or the F2B back to an Australian Shepherd) which will give you a puppy that is greater than 50% Australian Shepherd. This generation is great for those who are looking for something with a high percentage of Australian Shepherd but wanting to have lighter or reduced shedding than a typical Australian Shepherd.
Which Aussiedoodle Generation Sheds the Least?
The shedding truly does depend on the genetics of the parents and the puppies, but I will lump these into four categories:
- Very Minimal to Nearly No Shedding: F1BB, F1B and F2B
- Very Light Shedding: Multigens
- Low Shedding: F1, F2, Ultra Aussiedoodles
- Shedding: Reverse F1B
**The shedding level still will depend on the genetics of the dog**
Which Aussiedoodle Generation is Best for Allergies?
When it comes to which generations are best for allergies, typically those with a higher percentage of poodle are best. However, not all allergies are related to shedding, so it is important to know what you are actually allergic too (dander, fur, saliva, etc). If I had to rank the generations from best to worst for allergies from my experience here is how I would rank them F1BB > F1B > Multigen > F2B > F2 > F1 > Ultra Aussiedoodle > Reverse F1B. Again, this depends alot on the genetics of the puppy, but this gives you a good idea of which generations to focus on if allergies are a concern.
Which Aussiedoodle Generation Is Best?
The answer to this question ultimately comes down to what best fits your lifestyle and family. But hre is a few breakdowns:
- Best for low shedding: F1BB, F1B, F2B
- Best for Allergies: F1BB, F1B, Multigen
- Best for traditional Aussie traits: Reverse F1B, Ultra Aussiedoodle
- Best Balanced Mix: F1
- Best Predictability: F1, F2B, Multigen
At the end of the day, when trying to decide between an F1 vs. F1B Aussiedoodle, every family is different and that’s exactly why understanding Aussiedoodle generations matters so much.
Some families prioritize low shedding and allergy-friendliness, while others are drawn to specific coat textures or more traditional Aussie traits. There’s no “one-size-fits-all” answer, but knowing the differences between generations can help you choose a puppy that truly fits your home and lifestyle.
