Bossi-Poo Size: Intro

The Boston Terrier-Poodle mix is one of those interesting Doodle breeds that never ceases to surprise us. For starters, there’s not much known about this Doodle breed, besides some of the basic facts we have based on their heritage. 

Getting your hands on a Bossi-Poo pup might be rather difficult, as these pups are quite new and relatively rare. But based on their amazingly fabulous purebred parents, both of whom are very well-known amongst dog lovers, we can expect the Bossi-Poo to be just as loving, friendly, and sweet-natured as its parents. 

Bossi-Poos have wonderful, lively personalities, and they make great family pets thanks to their eager to please temperament. They also tend to be quite active, so daily exercise is an absolute must for them. Plus, Bossi-Poos are very intelligent, which means that training your new Bossi-Poo pup should be an absolute breeze. 

But when it comes to the Bossi-Poo size, predicting the outcome may be a bit of a challenge. That’s usually the case with hybrid breeds, as we never know what we may end up with – their genetics play a huge role, and you can’t force nature! 

Bossi-Poo Size Predictions: How Big Does A Bossi-Poo Get?

The average Bossi-Poo size ranges between 10 and 25 pounds once fully grown. They usually grow between 10 and 15 inches tall at the shoulder, and they tend to have short and muscular bodies with rounded heads, much resembling the Boston Terrier.

*A dog’s height is measured from its withers, which is the highest part of its shoulder blades, not from the top of its head.

Although there can be some conflicting information about the Bossi-Poo size out there, these pups usually are created by using either Miniature or Toy Poodles in the mix. That’s because the purebred Boston Terrier is more on the smaller size with its average weight of 10 to 25 pounds. 

By the way, the Boston Terrier comes in three size categories just like the purebred Poodle. As you can imagine, the size of the Boston Terrier used in the mix will also play a role here.

Likewise, the Poodle comes in three different sizes – Standard, Miniature, and Toy. For the Boston Terrier-Poodle mix, the Standard Poodle is slightly too big with its average weight of 38 to 70 pounds as an adult. They’re also quite tall – ranging between 24 and 27 inches at the shoulder. 

For this reason, Miniature Poodles are most commonly used. However, if you’re very lucky, you might come across a Toy Bossi-Poo with a Toy Poodle parent. Miniature Poodles weigh just between 10 and 20 pounds and they stand at 10 to 15 inches at the shoulder. In contrast, the smallest Toy Poodle can weigh as little as 4 pounds and go up to 12 pounds once fully grown. 

Are There Different Sizes Of Bossi-Poo?

Since both purebred Poodles and Boston Terriers come in multiple size categories, the Boston Terrier-Poodle mix can also vary in size. Like with other Poodle mixes and crossbreed dogs, the size of the puppies in a litter depends on their genetics, the size of their parents, and their generation. 

On the other hand, even though a breeder can do everything on their end to breed a certain size of Bossi-Poo, it’s never possible for them to guarantee the puppies’ exact size. Remember, even puppies from the same litter can range in size, as some are naturally larger, whereas others can be significantly smaller. 

Another thing to note is that as the Bossi-Poo is a new and rare Doodle breed, there aren’t exact ‘breed standards’ in terms of the Bossi-Poo size, nor is there exact agreement on how each size category is called. Some breeders might call the larger Bossi-Poo size either Mini or Standard – Mini is often used as the Poodle used in the mix is a Miniature Poodle. On the other hand, as this Bossi-Poo size is the larger of them, some breeders also opt to call them Standard Bossi-Poos due to their larger stature. 

The same goes for the smaller Bossi-Poo size. Since Toy Poodle is used in the mix, some breeders call them Toy Bossi-Poos, whereas others simply go with Mini Bossi-Poo, as they’re quite literally miniature versions of this crossbreed. 

Regardless of the case, it’s vital that you inquire about this from the breeder directly so that there are no misunderstandings. 

How Generation Can Affect Bossi-Poo Size

Interestingly enough, a Bossi-Poo’s generation could be one key factor affecting their size. If you don’t know what generations are, then we’re going to warn you – it can be a bit of a complicated topic at first. Let’s talk about it…

Essentially, a Bossi-Poo’s generation tells us how a litter of puppies was bred. With purebred dogs, the breeding process is rather straightforward – two health screened purebred dogs are crossed to produce a litter of puppies. However, with hybrid breeds like the Boston Terrier-Poodle mix, there are numerous ways to produce a litter of puppies. We can cross a purebred Boston Terrier with a purebred Poodle. Or, backcross a Bossi-Poo back to a Poodle. 

Naturally, this will also help us gain a better understanding of the possible outcome. Namely, when it comes to the Bossi-Poo size, coat type, and looks. That’s because with different generations the genetic makeup of the pups will be different, leaning on either side of their lineage. This chart below will help explain it all.

Gender Differences

Oftentimes, male dogs can be slightly bigger than females. However, this is more common in large and giant breeds, where the size difference is more significant. For smaller breeds like the Bossi-Poo, there usually isn’t much difference between males and females. 

Bossi-Poo Size Charts & Growth Patterns

Dogs generally grow the fastest in the first 50% of their adult weight, after which their growth rates will start to gradually slow down. This often correlates to the first six months of a dog’s life. However, as the Bossi-Poo size is on the smaller end of the scale, these pups tend to reach half their adult weight slightly sooner than that. 

Another thing to note with dogs is that they usually finish growing in height a few months before reaching their full adult weight. So, don’t be surprised if your little pup looks tall enough for a grown pup, but doesn’t seem to be as girthy just yet. Their weight will catch up soon!

Standard/Mini Bossi-Poo Size

The larger variation of the Bossi-Poo size is considered as a mini/medium sized dog. These pups generally reach half their adult weight between 3.5 and 5 months of age, plateauing at their full-grown weight between 11 and 13 months old. 

If you’re up for a quick calculation, try this formula to predict your Bossi-Poo’s size:

Mini/Toy Bossi-Poo Size

Typically, smaller dogs tend to finish growing sooner than larger dogs, and the Bossi-Poo is no different. Smaller Bossi-Poos usually reach half their adult weight around 3.5 months of age, and they’ll then plateau at their full adult weight between 7.5 and 11 months of age.

How Big Will My Bossi-Poo Get?

How Big Is A Mini Bossi-Poo?

As there are currently no breed standards for the Bossi-Poo size, the Mini Bossi-Poo can either refer to the larger Bossi-Poo size where a Miniature Poodle has been used in the mix, or the smaller Bossi-Poo size where a Toy Poodle has been used in the mix. Larger Bossi-Poos with a Miniature Poodle parent generally weigh between 15 and 25 pounds as adults, whereas smaller Bossi-Poos with a Toy Poodle parent weigh less than 15 pounds.
