A Sheepadoodle is undoubtedly adorable, with a gorgeous, long, silky coat, a kind, easy-going demeanour, and a clever, observant temperament.

They resemble a cuddly teddy bear as pups, and owners often hope that their lovely, tiny dog would remain that size forever.

Regrettably, all pups must mature. Some, like a Sheepadoodle, will grow to be very large, while others will not. So if they grow to be very large and they travel a lot in your vehicle, we recommend some vehicle cargo protection.

How big does a Sheepadoodle get?

Sheepadoodles typically weigh 50 to 80 pounds and stand 18 to 28 inches in height at the shoulder, but some may surpass this range depending on a variety of circumstances. When a smaller Poodle is utilised for breeding, the size of the resultant puppies is reduced.

Crossbreeds, such as Sheepadoodles, come in a wide range of sizes and are notoriously difficult to anticipate. The mature size of a puppy is determined by a number of variables, but an estimate may be made. To discover more, keep reading.

What Determines the Size of a Sheepadoodle?


Dogs, like humans, get half of their genetic composition from each parent. Some hereditary characteristics will be manifested (that is, their effects will be visible), while others will not.

When studying genes and alleles in high school biology class, you may remember learning about dominance and recession and how a dominant allele would “win” even if only one is present.

For example, since the gene for brown eye colour is dominant, you will have brown eyes if you have one copy of the brown eye allele and one copy of the blue eye allele.

Because of the two distinct breeds involved, things become a bit tougher and harder to anticipate with a crossbreed like a Sheepadoodle. Let’s look at both parent breeds to see how they may affect the size of your puppy in the future.

Old English Sheepdog

The American Kennel Club (AKC) does not put nearly as much attention on the weight of an Old English Sheepdog as it does on the dog’s general conformation and temperament, thus weight may vary greatly within the breed. According to AKC guidelines, any weight between 60 and 100 pounds is allowed.

It is generally recognised that a puppy’s mother has a greater impact on his growth than his father. The female utilised in nearly all Sheepadoodle breedings is an Old English Sheepdog, which explains why Sheepadoodles are often bigger than a Standard Poodle’s weight range.

Smaller Sheepdogs will naturally produce tiny pups, whereas larger Sheepdogs will often produce larger puppies. Remember that the size of the father (typically a Standard Poodle) will have an impact on the puppy’s size, so forecasting a pup’s eventual adult size simply based on the mother’s size isn’t completely correct.

Sheepadoodle - characteristics, appearance and pictures


Male Standard Poodles, which are most often utilised to create Sheepadoodles, must weigh between 60 and 70 pounds and stand over 15 inches tall, according to the AKC. Although this weight range corresponds to the Sheepadoodle’s typical size, many Sheepadoodles weigh much more than 70 pounds, particularly if the Sheepdog mother was big.

It’s fair to assume that a Sheepadoodle litter’s ultimate size is limited by the size of the Poodles. If this were not the case, the majority of Sheepadoodles would be much bigger than they are.

To create Mini Sheepadoodles, some breeders utilise a Miniature Poodle, which weighs between 10 and 15 pounds and stands between 10 and 15 inches tall. These smaller versions weigh between 24 and 45 pounds and stand no more than 20 inches tall.

Sheepadoodles bred by other breeders are known as Moyen Sheepadoodles. This merely indicates that the Poodle utilised in the breeding process was a Moyen Poodle.

Moyens, also known as medium or Klein Poodles, fall between the Standard and Miniature Poodle weight ranges. They’re more in the middle, weighing 20 to 40 pounds and measuring 15 to 20 inches tall. Some European breed organisations accept this non-standard size, however, the AKC and the United Kennel Club do not.

Moyen Sheepadoodles weigh between 40 and 55 pounds on average and are naturally shorter than Standard Sheepadoodles. They should have the same disposition as any other Sheepadoodle.


Males are typically taller and heavier than females in nearly all dogs, whether purebred or crossbred. Of course, there are always exceptions to the norm, but in general, males are larger than girls.

Sheepadoodles aren’t all first-generation (F1), which means they weren’t produced with an Old English Sheepdog and a Poodle.

To improve low-shedding characteristics or decrease the size of the pups, an F1 Sheepadoodle is sometimes mated to a standard or tiny Poodle.

When an F1 Sheepadoodle is crossed with a Miniature Poodle, the resultant pups are known as an F1b generation, with the “b” standing for backcross, and are anticipated to be smaller than Standard Sheepadoodles.

Backcrossing Toy Poodles to create even smaller versions is done by certain breeders, but artificial insemination is generally needed, resulting in considerably more costly pups.


Malnourished Sheepadoodles and those with intestinal parasites may suffer stunted development, never reaching their full height and weight potential.

Dogs, on the other hand, do not excel at self-discipline when it comes to food, and if portion management is not correctly managed by the owner, dogs may quickly become fat, endangering their health.

How to Estimate a Dog’s Adult Weight

While there is no way to predict how large your Sheepadoodle will grow up to be, there are a few techniques that can give you a rough estimate.

You’ll need an exact weight for your puppy for each technique. To do so, either take him to your veterinarian’s office for a fast weigh-in or hold him in your arms while standing on your bathroom scale, record the weight, then weigh yourself (I know, it’s never pleasant) and deduct your weight from the first one.

How Much Do Sheepadoodles Cost? - Fondpets

Method #1: 

Multiplying 25 by 2.5, for example, shows that a puppy weighing 25 pounds at 14 weeks would likely reach an adult weight of about 62 12 pounds.

Method #2: 

When your Sheepadoodle is 20 weeks old, get his weight. Multiply this value by 52 after dividing it by 20.

So, if a puppy weighs 30 pounds at 20 weeks, his ultimate weight is anticipated to be approximately 78 pounds (30/20 = 1.5, then 1.5 x 52 = 78).

Method #3 

If arithmetic makes you nervous, weigh your puppy and use an online puppy development calculator to perform the math for you.

You’ll also need your puppy’s date of birth, the day the weight was measured, and you’ll have to choose Old English Sheepdog from the breed list since crossbreeds aren’t included and your Sheepadoodle’s development rate will be closer to that of a Sheepdog than that of a Poodle.

When Will My Sheepadoodle Stop Growing?

Large dogs, such as Standard Sheepadoodles, require longer to mature than smaller dogs. A Sheepadoodle’s full height is usually reached around the 18-month mark, but he will continue to fill out as his body develops more muscle mass and fat until his second birthday.

When Are Sheepadoodles Considered To Be Fully Mature?

Many puppy habits, including accidents, nibbling on fingers, clumsiness, and chewing anything and everything, will have vanished by the time your Sheepadoodle reaches one year of age, and sexual maturity will have occurred.

Complete mental maturity, like physical development, typically occurs around the second birthday, and by the time your big guy reaches two, virtually all of the puppy behaviour will be gone, and your Sheepadoodle will be deemed completely grown.
