Did you know a “mini” Bernedoodle can weigh anywhere from 25 pounds to nearly double that size? Here’s the scoop on why the size can vary so much—and how to choose the perfect one.
How much do mini Bernedoodles weigh fully grown?
When people ask me how much mini Bernedoodles weigh, I usually say it’ll range between 25 and 50 pounds, although most fall between 25 and 45 pounds. Once you reach that 50-pound mark, you’re kind of moving into medium-sized territory.
Comparing mini Bernedoodles to toys, mediums, and standards
Bernedoodles come in different sizes, not just minis. Here’s a simple breakdown:
- Toy Bernedoodles: These are small dogs—typically under 25 pounds.
- Mini Bernedoodles: Generally 25–45 pounds, up to 50 pounds at times.
- Medium Bernedoodles: Usually 50–65 pounds.
- Standard Bernedoodles: Anything over 65 pounds falls into this category.
If you’re looking to have a smaller, manageable dog that doesn’t compromise on Bernedoodle temperament, mini or medium Bernedoodles are perfect. Among our customers, they’re the most popular sizes.
When is a mini Bernedoodle fully grown?
Your mini Bernedoodle hits its adult weight at around nine to ten months. By then, you’ll have a clear idea of how big they’ll get.
Do males and females differ?
Yes, males are usually a bit bigger than females, so keep that in mind as you select a puppy.
Why there’s variation in mini Bernedoodle sizes
Parent size & genetics
Predicting exactly how big a mini Bernedoodle will become depends heavily on the sizes of the parents. For instance:
- If both parents are very similar in size (let’s say 30–40 pounds each), you’ll get pretty consistent results in the puppies, likely staying in that range.
- When parents are vastly different (like a 15–20 pound dad and a 90-pound mom), the litter will have some puppies that lean smaller, others larger. In these cases, I’d label them “mini-medium” rather than pure mini because some in the litter might be mini and some will end up being more medium size.
The generation type (F1, F1b, multigen) also has an influence:
- F1 Bernedoodles: Often a Bernese mom and a smaller dad, can be unpredictable, usually varying 35–60 pounds.
- F1b Bernedoodles: A bit easier to control size, but still varies depending on parents.
- Multigens: Size consistency can be achieved with careful pairing, typically by combining two smaller sized Bernedoodles or a Bernedoodle and a mini Poodle.
So, if your set on getting a pup that’s like 40 pounds or less and really need a true mini puppy, make sure both parents are mini-sized (or close).
What influences your mini Bernedoodle’s final weight?
Alongside genetics, there are lifestyle factors too:
- Diet: Choosing quality food without fillers and appropriate portion sizes will help maintain a healthy weight. Bernedoodles can have sensitive stomachs, so you might find trial-and-error helpful. Salmon-based diets often work great because they’re gentle on digestion.
- Exercise: Regular activity is key! Aim for at least two good walks (about a couple miles total) per day or at least an hour of playtime in a fenced yard every day. This keeps them healthy and prevents unwanted weight gain.
- Spaying and neutering: Be aware that these procedures generally cause your dog to gain a bit of extra weight, mainly filling out their frame more fullyDaily feeding recommendations for healthy weight
For mini Bernedoodles around 30 pounds, I’d recommend feeding approximately 1/2 cup to 1 cup of quality food, twice a day (morning and evening) but always refer to your bag. It really does depend and vary on each brand. Adjust slightly based on your dog’s activity levels and optimal weight.
Costs and other practicalities of mini Bernedoodle ownership
In 2025, mini Bernedoodles typically cost between $2,000 and $6,000 in purchase price, averaging around $3,500. At our facility, size doesn’t affect pricing—whether toy, mini, medium, or standard, we maintain consistent pricing.
Closing thoughts from my experience
If you’re set on a specific size (say under 40 pounds for easy handling and a relaxed lifestyle), research the parents’ sizes carefully. Always pick puppies whose parents are both mini-sized, ensuring you won’t end up bringing home a pup that grows bigger than anticipated. If you want a big dog then make sure both parents are big. Then if you’re ok with a 35 pound dog but also a 55-60 pound one is ok with you then a mini/medium will work great. Thats when the parents are widely different in size.
