How Big Will An F1B Goldendoodle Get?

I have been thinking about F1B Goldendoodle sizes a lot lately. They are a fascinating crossbreed that ends up with roughly 75% Goldendoodle genetics and 25% Golden Retriever genetics. This results in all sorts of interesting differences from F1 Goldendoodles. Coat, temperament, and particularly, the size of the F1b Goldendoodles has a lot of variation influenced by their Poodle parent.

Poodles can be huge or tiny, so what does that mean for F1B Goldendoodles? What can you expect the size of the full-grown F1b Goldendoodle to be?

How big do F1B Goldendoodles get?

Depending on the size of the Poodle parent, an F1B Goldendoodle may up to 85 pounds and 25 inches tall or as small as 10 pounds and about 10 inches tall. Most F1B Goldendoodles are between 25 and 60 pounds and stand between 16 and 23 inches tall, but it all depends on the size of the Poodle parent.

The F1B Goldendoodle is a backcrossed F1 Goldendoodle bred with a Poodle. Because the Poodle parent of an F1B Goldendoodle could be any size, from a Standard Poodle (up to 90 pounds and 28 inches tall) to a Toy Poodle (as small as 6 pounds and only 8 inches tall), the resulting F1b Goldendoodle’s size will vary dramatically. However, most end up a medium size in between the two extremes.

The F1B can grow as big as about eighty lbs. in weight.  This weight depends on which type of F1B Goldendoodle is selected and the size of the Poodle parent.

Various sizes include petite, miniature, toy, and standard.  Each one of these sizes will be slightly more in weight to a varying degree.  If a miniature F1 Goldendoodle is bred with a Poodle, the F1B Goldendoodle size will be different from a small, medium, or standard-sized F1 Goldendoodle and Poodle parent pair.  

Height can reach around 21 inches to the withers, but this is a guideline, nothing etched in stone.  Weight and height will vary with each pup in a particular litter, ranging slightly up or down, but each dog is equally unique and will carry with them their own special traits. 

The sex of the F1b Goldendoodle is also a factor. In general, males will be larger than females of the same litter.

It can be challenging for breeders to determine precisely how big the puppies will be, but they can offer a range when breeding a particular parent pair.  

Some factors help determine how big an F1B Golden Doodle gets, and puppy parents should not limit themselves to a particular F1B Goldendoodle based solely on size unless there is a particular need, say, back-related issues or other health problems that would make it more important for them to have a smaller dog.  Each dog is unique in size, temperament, personality, character, intelligence, and appearance.

The F1 Goldendoodle is the original, first-generation Goldendoodle bred from two purebred parent breeds, a Golden Retriever and Standard Poodle.  Their parents help determine how big or small they will be in height and weight and other physical, mental, and emotional attributes.

When an F1 Goldendoodle is backcrossed and bred to a Poodle again, it creates an F1B Goldendoodle, a first-generation backcrossed Goldendoodle.  The size of these puppies will vary depending on a few factors.

The F1 Goldendoodle size will figure into how big or small the F1B Goldendoodle will become.  Another determining factor is what type of purebred Poodle is selected. 

Traditionally the Standard Poodle would be a parent, but these designer dogs are often backcrossed with a miniature, small or standard Poodle.  This can affect how big or small the F1B Goldendoodle is concerning height and weight.

This variance in size is not a large one but can be seen in dogs that come from the same litter.  One F1B Goldendoodle might be average weight closely resembling one of the parents, but a little shorter than the parents.  Another F1B Goldendoodle of that same litter might weigh slightly more than both parents but be taller than one of them as well.

A person may prefer a smaller, mini F1B Goldendoodle if they suffer from allergies. All Goldendoodles are non-shedding or low-shedding, but there are other dog allergens they still possess, like saliva and urine, to name a few.

A smaller dog like a min F1B Goldendoodle will not only have tighter curls and like the mini Poodle parent but also just be smaller, producing fewer allergens overall. The size of the Goldendoodle is a major factor affecting how hypoallergenic they are. This is why different sizes of Goldendoodles are so convenient! This mixed breed dog can meet anyone’s lifestyle, regardless of size needs.

How do I go about getting a particular sized F1B Goldendoodle if I want one that is big?

For potential pet parents to have a greater chance of getting a particular sized F1B Goldendoodle that is big or small, choose the right breeder.

Selecting the right breeder that has experience and knowledge provides the best possible outcome.  While nothing is guaranteed concerning how the hybrid puppies of a F1 Goldendoodle back cross with a Poodle will turn out, a knowledgeable, reputable breeder will have more skill at selecting the right parents to offer the best chance at success.   They also offer a higher likelihood of getting closer to what pet parents are looking for in a Goldendoodle.

Thankfully there are a large number of skilled, experienced, and knowledgeable F1B Goldendoodle breeders out there today, making it easier for potential pet parents to find their perfect match.

Are there certain things I can do to help my F1B Goldendoodle get bigger?

Yes and no.  There is not anything that a human parent can do to help their F1B Goldendoodle grow bigger in height.  Genetics is the determining factor in how big or small the hybrid dog will be concerning height.  Like temperament, coat of fur, and intelligence, height is based solely on the parents’ genetics.

That being said, some things can be done to help make a slightly smaller or potentially less healthy F1B Goldendoodle bigger in weight.  It is also possible to reduce the weight of a dog that is unhealthy and too large for their own good.  Nutrition is the key to finding the right weight for a particular F1B Goldendoodle, no matter how big or small they get.

The first place to start is with the F1B Goldendoodles diet.  Once they are weaned from their mother and littermates and brought to their new home, ensuring that they have a healthy and nutritious diet can go a long way towards helping a smaller or less healthy puppy grow big and strong.  The same can be said for the over-enthusiastic F1B Goldendoodle that loves to eat a bit too much.

The right kind of dog food provided from the first moment they are welcomed into their new home, and the right amount will maintain overall health and a robust physical constitution.

Their diet should be discussed with the veterinarian at their check-up since they will know what is best for the F1B Goldendoodle puppy regardless of how big they get. 

Certain dietary guidelines must be followed for every puppy to ensure good health.  Each dog is unique with regard to their dietary needs.  While the F1B Goldendoodle dog breed will have specific dietary needs related to their genetics, each dog will have specific needs related to who they are.

Overall health can’t be measured by height and weight alone.  Therefore feeding large amounts of food to increase how big they are weight-wise can sometimes do more harm than good for the puppy.  The same can be said for reducing their intake of food to help them become smaller if they are too big.

Is it better to have a bigger F1B Goldendoodle versus a small one?

Not necessarily.  Neither big nor small F1B Goldendoodles are better than another, just different.  As with any dog, the size won’t affect their temperament or how loving and affectionate they are to their family.

The perfect scenario is selecting a dog that is right for the family, one that fits their lifestyle and that they enjoy spending affectionate bonding time within a loving environment.  Size might seem like the most important factor but that isn’t always the case.

Is the F1 Goldendoodle more likely to influence how big the F1B Goldendoodle becomes?

This is a hard question to answer.  When it comes to backcrossing a dog, we have to remember that the litter of puppies will have more of the traits of the parent that was backcrossed with, in this case, the Poodle.

How big the F1B Goldendoodle will become is more influenced by the Poodle genes because more of those genes are in that dog.

If a F1 Goldendoodle is backcrossed with a standard-sized Poodle, yes, the F1B Goldendoodle will be bigger than the F1 Goldendoodle’s puppies backcrossed with a Miniature Poodle. If they are backcrossed with a Standard poodle, you’ll have a standard Goldendoodle (F1b). If they are backcrossed with a Mini Poodle, you’ll end up with a mini Goldendoodle (F1b).

This doesn’t mean the Poodle parent will solely determine that size.   How big a F1B Goldendoodle becomes can still be related to the F1 Goldendoodle. 

While there is a higher likelihood of more Poodle genes in the puppies since there are more of those genes, it is still possible for some of the original purebred Golden Retriever parental genes to shine through in the F1 Goldendoodle parent.

This situation might produce an F1B Goldendoodle litter with one dog being bigger than all the others with more Golden Retriever traits in them.  They might be bigger in height, weight, or both.

While most of the litter will have a dominance of the Poodle traits, including physical, mental, and emotional, there is still the potential for Golden Retriever traits to pop up in various ways. 

When they do, these traits will vary from dog to dog in the same litter.  It can make for interesting combinations and surprises for both breeders and clients.

With cross-bred dogs are backcrossed to their pure-bred parent, results can vary from dog to dog, even in the same litter.  Breeders that are trained and skilled can get an idea by looking at each litter of puppies and each individual dog but surprises will still happen.

Closing Thoughts

While nothing in life is predictable, including the height and weight of an F1B Go01ldendoodle, their parents determine how big they get.

The F1B Goldendoodle can have a wide range of sizes depending on the parent pair.  Despite this, size isn’t the only factor that should be considered when selecting a F1B Goldendoodle.

For true happiness based on love, affection, and a strong bond, such things as temperament, personality, and character should be most important.  Appearance is only skin deep; this is true even for a dog!
