How Big Can A Sheepadoodle Get?

You are currently viewing How Big Can A Sheepadoodle Get?

If I did not know about Sheepadoodles, I probably would have thought they are stuffed animas because they are that much fluffy and adorable. However, they look that way due to being a mixed-breed with Poodle and Old English sheepdog. Also, these guys have great personality traits such as being affectionate, smart, playful and even-tempered. The best pet traits huh.

So all those factors have made you want to know how big a dog of this breed can get before getting one yourself right? Well then, here is the answer for you.

On average, a Sheepadoodle can grow about 60-80 pounds in weight (27-36 kg) and 16-23 inches in height (40.6-58 cm). However, in terms of the size distinction between males and females, an average male can weigh between 60 and 75 pounds (27-34 kg) whereas an average female is capable of growing 45 to 70 pounds (20-31.7kg).

But remember, these are just averages and depending on factors such as health conditions and different breed lines, the size can surely differ from one Sheepadoodle to another.

What are the three Sheepadoodle sizes based on their generations?

Based on the breed makeup of the sheepadoodles, they can be classified into three main sizes.

MiniatureMini and Medium25-55 pounds15-22 inches12 – 14 month
ToyMicro/Small/Toy10-25 pounds15 inches or less13 – 16 months

These three sizes are classified based on the Sheepadoodle Generations. So here are those generations:

What determines the size of a Sheepadoodle?

There are a number of factors that cause the size of these doggos to be either on the smaller side or the bigger side of the spectrum.

Here are those factors:


As shown above, the three sizes are determined mainly based on the generations and initially, the Sheepadoodles were bred with Old English Sheepadogs and Poodles which is what you call the first generation (F1) Sheepadoodle.

And then, F1 sheepadoodles were bred with poodles in order to increase the ability of low-shedding but as a result, these dogs also became smaller.

From that time onwards, to breed smaller dogs, F1 sheepadoodles and poodles were used but when F1 is crossed with a Miniature, F1b are born and then they became even smaller.

Now you see, there is a pattern. Through using different generations with the Poodle or the Old English Sheepdog, new generations are born with size-differences.

And depending on the breeder’s intentions, breeding process is done to get these different-sized Sheepadoodles and this factor might be the most prominent one in terms of impacting the sizes of a Sheepadoodle.

The diet

Diet plays a major role in the growth process of any dog and if a dog is not fed with proper portions and required nutrition, not only their growth gets hindered but they will also suffer quite a lot from the under-fed state.

Due to that, a Sheepadoodle will not reach their genetic potential in growth of height and weight. Therefore, as a pet-parent, you must ensure you know the basic knowledge of how to feed your Sheepadoodle the right way with the suitable amounts.

However, if you do not know how to manage the diet and the potion sizes, then you should go to a vet and consult with them. They will give you an exact diet with the potion sizes for your dog based on its weight, height and the age. That is the best call.


Size-differences in the animal kingdom is such a normal thing and it is the same for the dogs as well. The males tend to grow a bit bigger and heavier than the females due to the distinctive biological traits but there can be exceptions to this too. However, mostly, it is a usual thing to see bigger male Sheepadoodles than Females.

Here is an in-depth overview of the three Sheepadoodle sizes

Standard Sheepadoodle

This size is the most regular one when it comes to these doggos. This is an outcome of crossing an Old English Sheepdog with a Standard Poodle. Both these parent breeds are large-sized dogs.

Old English Sheepdog usually grows 60 to 100 pounds in weight and 20 to 25 inches in height while the Standard Poodle is capable of becoming about 18 to 25 inches in height and 45 to 70 pounds in weight.

Now just imagine, the potential that a crossbreed puppy of the two breeds will have in height and weight growth. It is pretty comprehensive. Now, isn’t it?! but however, with excellent physical and mental states and quality maintenance, a standard-sized Sheepadoodle can top to even over 100 pounds.

Nonetheless, remember that sometimes, their looks can be deceiving, meaning you can not tell whether a Sheepadoodle weigh much or not solely based on the appearance because some of these dogs can have really short legs inheriting from Old English Sheepdog and those short logs can make a dog look small.

Mini Sheepadoodle (Miniature)

This is the medium-sized Sheepadoodle that is smaller than the Standard one but yet bigger than the Micro one. Although, the word Mini gives a meaning to the dog as if it is a smaller dog, these Mini Sheepadoodles can get quite big.

This size of a sheepadoodle is born when a Mini Poodle is paired with an Old English Sheepdog but what makes these guys bigger is a breed line coming from the Old English Sheepdog since they weigh around 60 to 100 pounds with a height of 20 to 24 inches.

And when it is crossed with the Mini Poodle that weighs around 12 to 20 pounds in weight with a height of 15 inches, the Mini Sheepadoodles are born.

Micro Sheepadoodle (Toy)

The smallest size of the Sheepadoodles is a breed crossed with Poodle and Mini Sheepadoodle instead of the large-sized, Old Englished Sheepdog.

As you can see above from the table, Micro-sized doggos only weigh 10 to 25 pounds with a height of 15 inches or less.

That is to say, a Mini Sheepadoodle is 25 to 50 pounds in weight with a height of 16 to 18 inches and then, when it is mixed with a standard Poodle, the is the outcome is a Micro/Toy Sheepadoodle.

When does a Sheepadoodle finish growing fully?

Smaller dogs such as Mini and Micro-sized dogs take less time to reach the genetic potential in growing.

However, an average Sheepadoodle will take about 18 months to get to its maximum height and weight. So until their second birthday, they will gain muscles and fat to fill out.

The lifespan of a sheepadoodle according to the three sizes

On average, the lifespan of this breed is 12 to 15 years but when it is compared with the three different sizes, the ages can be different and they are as the following:

Sheepadoodles of the size Miniature  – 13 to 16 years

Sheepadoodles of the size Toy  – 13 to 17 years

Sheepadoodles of the size Standard – 10 to 13 years       

As you can see, smaller and medium-sized Sheepadoodles tend to live longer than the standard-sized ones.

The reason for this is simple. The larger-sized dogs such as the standard-sized Sheepadoodles put more pressure on the physiological processes which is why they grow bigger but on the other hand, that caused them to age faster than the smaller dogs.

Due to that fact, toy and Miniature Sheepadoodles live about 3 to 4 years longer than the Standard-sized ones.

Final Thoughts

it is safe to say that these adorable and stuffed animal looking doggos are perfect to have as pets since they come in three sizes for you to choose from and also, they have such great personality traits.

Anyway, I hope the answer to how big a Sheepadoodle can get was found helpful by you fellow hoomans and thank you for reading.
