The Saint Berdoodle, also known as Saint Berpoo, St Berpoo, and St Berdoodle, is a cross between a Saint Bernard and a Poodle. As a recent breed, there are no specific standards for Saint Berdoodles. All we can really say for sure is that they are pretty big dogs, given that Saint Bernards are categorized as large and Standard Poodles as medium to large. However, if you really want to know how large your Saint Berdoodle will get, in this article you can view our interactive Saint Berdoodle size chart and calculator to help answer that question.
The Different Types of Saint Berdoodles
These bear-like dogs might appear intimidating to those not in the know. However, they are keenly sociable creatures with the Poodle’s adventurous spirit and the St Bernard’s laid-back attitude. The output of which is a dog who enjoys roaming outdoors almost as much as they love napping.
Friendly, intelligent, and loyal, St Berdoodles make excellent pets for those with plenty of space to house them (they are the largest of the Doodles) and plenty of time to give them the attention they crave. They do best in a home where they can be around family for most of the time, and they love kids – their parent pups Saint Bernards aren’t known as the ‘nanny dogs’ for nothing.
These affable canines frequently forget their sheer size in their ultimate quest to be close to the ones that they love. Luckily for those who desire the same kind of friendship but in a slightly more manageable package, breeders have begun to incorporate Miniature Poodles into the mix. The Mini Saint Berdoodle has all the personality and affectionate nature of their larger counterparts without any of the crushed ribs!
Whichever type you opt for, there are multiple varieties. While Saint Berdoodles are a younger Doodle breed, they are gaining in popularity. So we are starting to see second and even third generations. See below for an explanation of what this means:

Saint Berdoodle Size Predictions
Being able to predict your puppy’s potential adult size enables you to be fully prepared for what’s to come in terms of setting aside the right amount of space for them, picking out the right sized accessories, and incorporating their dietary needs into your budget. All super helpful!
Even if you opt for a Mini St Berdoodle, you need to know that you’re getting no lap dog. These are good-sized dogs and could just as easily take after their massive parent as their smaller-sized one. Just think, though… the bigger the dog, the more there is to cuddle – and your St Berdoodle will be more than happy to oblige.
Keeping a close eye on your pup’s growth patterns could tell you all you need to know about their adult size with the help of our excellent interactive Saint Berdoodle puppy growth calculator.
The below Saint Berdoodle size chart / graph shows the average weights by age (in weeks), by size of Saint Berdoodle. It shows weight data from our Doodle Weight Prediction Calculator.
As of October 24, 2022, we’ve received over 4,200 accurate Saint Berdoodle weight submissions through our calculator.
Saint Berdoodle Size Charts & Growth Patterns
Let’s take a look at those all-important sizes:
| Mini Saint Berdoodle | Standard Saint Berdoodle | |
| Weight | 30-55 pounds | 55-150 pounds |
| Height* | 14-24 inches tall at the shoulder | 24-30 inches tall at the shoulder |
| Age at Full-Grown | 12-18 Months | 18-36 Months |
The larger Saint Berdoodles will likely reach their adult height around 18 months but will continue to bulk out long past that. However, their most significant growth period occurs in the first year of their lives – especially within the first 6 months or so – so you don’t have to worry about them suddenly doubling in size beyond this.
From what we know of Miniature Poodles, the Mini St Berdoodle will do the vast majority of their growing in the first 6 months of their life. They will reach roughly adult height before their first birthday. Beyond that, they will continue to gain weight until approximately somewhere between 18 and 24 months, depending on whether they’re at the lower and larger end of the size scale.
This is why it’s particularly important that your Saint Berdoodle puppy gets the correct nourishment he needs to grow that adorable little body into a healthy adult one. Check out our guides on best dog food for Doodle puppies here.
Saint Berdoodles
Saint Berdoodles generally reach half their full weight around 6 months and their adult weight between 18 and 36 months.
You can calculate their potential adult weight at 23 weeks by taking what they weigh at that age and multiplying it by two.
Mini Saint Berdoodles
Mini Saint Berdoodles also generally reach half their full weight around 5 months and their adult weight between 12 and 18 months.
You can calculate their potential adult weight at 18 weeks by taking what they weigh at that age and multiplying it by two.
A different formula you could use is:
At What Age Are Saint Berdoodles Considered Fully Grown?
While your Mini Saint Berdoodle might well be full-grown by the time they are 18 months old, your Standard Saint Berdoodle will likely take considerably longer. In fact, they could continue growing right up until the age of three. Rest assured, though, that this will be outwards, not upwards! They will likely have achieved their adult height much earlier, around 12-18 months.
If you want to narrow the time frame a little more, understanding your puppy’s potential adult size can assist you a great deal with doing this. Keeping an eye on their growth and consulting with our interactive puppy growth calculator can help you assess where they are likely to stand. Knowing the height of their parents offers up vital clues, and finally, gender also plays a role with this breed. Males are far more likely to be at the larger end of the scale, with females being smaller.
