Bernedoodle Sizes: Toy, Petite, Mini, Medium, Standard & Ultra

How big does a Bernedoodle get? Bernedoodle adult size is determined primarily by the Poodle parent. Stokeshire breeds the full ladder of six size classes per the Stokeshire Doodle Size Standard, from Toy (up to 15 lb) through Ultra (90 lb and above). The Petite tier sits in its own program: the Munchkin Bernedoodle, which adds Cavalier King Charles Spaniel heritage to stabilize the smaller size. This guide covers each class, the growth timeline from eight weeks through maturity, the 16-week doubling formula, and the lifestyle fit for each tier.

The Stokeshire Doodle Size Standard. The Goldendoodle Association of North America (GANA) holds the only widely recognized doodle size standard, and it covers Goldendoodles only. For Bernedoodle, Aussiedoodle, Australian Mountain Doodle, and Golden Mountain Doodle, no breed authority exists. Stokeshire publishes the canonical six-class standard that every breed page reconciles to.

Size at a Glance

Bernedoodle Size Classifications

Bernedoodle size is determined primarily by the Poodle parent. The Bernese Mountain Dog parent is always a large dog (typically 70 to 115 lb), so the Poodle parent and the generation of the cross are the primary levers breeders use to control adult size. Standard Poodle crosses produce Standard and Ultra Bernedoodles. Miniature Poodle crosses produce Mini and Medium classes. Toy Poodle crosses produce Toy Bernedoodles. The Petite class is produced under the Munchkin Bernedoodle program, which adds Cavalier King Charles Spaniel heritage to stabilize the smaller frame.

Class 1

Toy

up to 15 lb
under 13 in at the withers
Anchor: coffee-table height

Toy Poodle cross through multigenerational lines. Growth typically complete by 8 to 12 months. Apartment-suited, travel-friendly, often airline cabin eligible. Best for households without rough play.

Class 2

Petite

16 to 25 lb
12 to 15 in at the withers
Anchor: side-table height

Produced under the Munchkin Bernedoodle program, which adds Cavalier King Charles Spaniel heritage. The lap-and-couch tier. Petite is the program name; Munchkin is the line.

Class 3

Mini

26 to 35 lb
14 to 17 in at the withers
Anchor: couch-armrest height

Miniature Poodle cross. Growth typically complete by 10 to 14 months. The most requested Stokeshire tier across all breeds. Active families, urban professionals, suburban homes.

Class 4

Medium

36 to 50 lb
17 to 21 in at the withers
Anchor: kitchen-counter underside

Moyen or small Standard Poodle cross. Growth typically complete by 12 to 16 months. Family households with children, larger homes, and outdoor lifestyles. Comfortable on hikes and on the couch.

Class 5

Standard

51 lb and up
over 21 in at the withers
Anchor: thigh-high on a 5′8″ adult

Standard Poodle cross. Typical adult range 70 to 90 lb. Skeletal maturity at 18 to 24 months. Deep-chested, so bloat awareness applies. Best for families with space and a vehicle that fits a Standard crate.

Class 6

Ultra

90 to 115+ lb
over 23 in at the withers
Anchor: five-year-old at the shoulder

Reverse F1B cross with stronger Bernese influence. Stokeshire does not specifically breed for Ultra outcomes. Reserved for families with experience with very large dogs and the space to support them well.

Adult size is typical, not guaranteed. Final size is confirmed at maturity and influenced primarily by the Poodle parent. Individual puppies may finish 15 to 20 percent above or below the band. Females tend toward the lower end of each range, males toward the upper.

Lifespan data is based on parent breed longevity research and Stokeshire breeding records. Lifespan is also influenced by parent health testing quality, body weight management, diet, and consistent veterinary care. Smaller classes tend to live longer than larger classes.


The Lap-and-Couch Tier

Petite Bernedoodles: The Munchkin Program

The Petite Bernedoodle is produced under the Stokeshire Munchkin Bernedoodle program, which adds Cavalier King Charles Spaniel heritage to stabilize a smaller adult size and soften temperament for family-home placement. Petite is the size classification per the Stokeshire Doodle Size Standard. Munchkin is the program name and the line.

Petite Bernedoodles typically mature at 16 to 25 lb and stand 12 to 15 in at the withers. The CKCS contribution adds an even-tempered, family-oriented temperament that suits homes with children, mobility considerations, or apartment buildings with weight ceilings. A typical Petite Bernedoodle matures under the 25-pound limit many luxury condos and co-ops enforce. We hedge that intentionally. Adult size is not guaranteed, and we do not recommend selecting a Petite puppy based on a strict weight threshold without veterinary consultation.

Petite is not the same as Toy.

The Toy class (up to 15 lb) sits below Petite on the ladder and is produced through pure Bernedoodle multigenerational lines with a Toy Poodle ancestor. The Petite class (16 to 25 lb) is the Munchkin program and is a distinct cross that includes Cavalier King Charles Spaniel heritage. Both classes deliver a smaller-frame Bernedoodle, but they are produced through different breeding programs and result in different temperament profiles.

The Largest Class

What Is an Ultra Bernedoodle?

An Ultra Bernedoodle is a Bernedoodle that exceeds the Standard class, typically weighing 90 to 115 lb or more with a frame that leans heavily toward the Bernese Mountain Dog parent. Ultra outcomes are produced through Reverse F1B crosses (F1 Bernedoodle × Bernese Mountain Dog, resulting in approximately 75 percent Bernese and 25 percent Poodle) or through Standard crosses where both parents carry genetics for larger frames.

Stokeshire's Position on Ultra Outcomes

Stokeshire does not specifically breed for Ultra outcomes. Selecting for maximum size compromises structural soundness. Ultra-range puppies do occur in our Reverse F1B litters, but the program is not optimized for maximum size, and we do not promise an Ultra outcome in any pairing. Families specifically seeking a giant-frame dog should plan for the variability that comes with hybrid genetics: a puppy from a Reverse F1B litter may finish at Standard size rather than Ultra, and that variation is not a defect.

What to Plan For with an Ultra

Ultra Bernedoodles require more space, more food, and more veterinary attention than smaller variants. Their deep-chested, heavy-boned frame carries higher risk for bloat (GDV), hip and elbow dysplasia, and orthopedic stress during the prolonged growth phase of 20 to 24 months. Exercise management during puppyhood is critical. The five-minute rule (per month of age, twice daily) must be followed rigorously. Grooming costs are higher due to the larger coat surface area. Insurance premiums are typically higher for giant-breed dogs.

The coat in Ultra Bernedoodles varies. Reverse F1B Ultras tend to have straighter, more Bernese-like coats that shed more, and these are not appropriate for allergy-sensitive households. Standard-cross Ultras that carry stronger Poodle coat genetics may retain wavy or furnished coats with lower shedding, though this is less predictable at the Ultra size.

Typical lifespan estimates for Ultra Bernedoodles are 10 to 13 years, shorter than smaller variants, consistent with the general veterinary principle that larger dogs tend to have shorter lifespans than smaller dogs of the same breed or cross.

The Smallest Class

Toy Bernedoodles

Toy Bernedoodles are produced through Stokeshire's multigenerational Bernedoodle lines that have already established smaller sizing, paired with a Toy Poodle. Adults typically mature at up to 15 lb and stand under 13 in at the withers, finishing primary growth by 8 to 12 months.

Toy Bernedoodles carry the full Bernedoodle temperament (gentle, people-oriented, intelligent, playful) in the most portable frame. They are well-suited to apartment living, urban environments, and families who travel frequently and want a dog that can ride in an airline-approved cabin carrier. Their smaller size also makes them accessible to elderly owners or those who need a dog they can physically manage.

Considerations Specific to the Toy Class

Smaller dogs are more physically fragile. Toy Bernedoodles may not be appropriate for households with very young children who play roughly or may accidentally step on or drop the dog. Dental health becomes a more significant concern at the Toy size; smaller jaws are more prone to crowding, retained baby teeth, and periodontal disease. Hypoglycemia (low blood sugar) can be a concern in very small puppies, particularly during the first few weeks in a new home when stress may reduce appetite.

Toy Bernedoodles require less total exercise than Standards but still need daily structured activity and mental stimulation. Small size does not mean low maintenance. Their intelligence and need for engagement is identical to larger Bernedoodles.

On "Micro" and "Teacup" terminology.

The terms "Micro Bernedoodle" and "Teacup Bernedoodle" are marketing terms without standardized breed definitions. There is no distinct Micro class. Dogs marketed as Micro are typically Toy Bernedoodles at the smaller end of the range, or Petite Bernedoodles labeled inaccurately. Stokeshire uses the six-class Stokeshire Doodle Size Standard. Extremely small dogs (under 10 lb) may face additional health challenges related to fragile bone structure, dental issues, and difficulty regulating body temperature. Stokeshire does not endorse extreme miniaturization, and we recommend veterinary consultation before selecting any puppy targeted at the very low end of the band.


Development Timeline

Bernedoodle Growth Stages by Class

Growth rate in Bernedoodles is inversely correlated with adult class. Smaller classes reach skeletal maturity faster than larger ones. Standard and Ultra Bernedoodles may continue gaining muscle mass and bone density until 18 to 24 months, while Toy Bernedoodles often finish primary growth by 8 to 12 months. Understanding these timelines is critical for managing exercise, nutrition, and veterinary care during development.

Class8 Weeks4 Months6 Months12 MonthsFull Maturity
Toy2 to 4 lb5 to 9 lb7 to 12 lbup to 15 lbup to 15 lb (8 to 12 mo)
Petite3 to 5 lb7 to 12 lb10 to 18 lb16 to 25 lb16 to 25 lb (10 to 12 mo)
Mini5 to 8 lb12 to 18 lb18 to 26 lb22 to 32 lb26 to 35 lb (10 to 14 mo)
Medium7 to 12 lb16 to 25 lb22 to 35 lb32 to 45 lb36 to 50 lb (12 to 16 mo)
Standard10 to 20 lb25 to 40 lb40 to 60 lb60 to 80 lb51 lb+ typ. 70 to 90 (18 to 24 mo)

Weight ranges are approximate and based on parent breed data and Stokeshire breeding program observations. Individual variation is normal. Puppies from the same litter may finish at different adult sizes depending on which parent's genetics are more expressed.

The 16-Week Doubling Formula

A common predictive method used by breeders to estimate adult weight: take the puppy's weight at 16 to 18 weeks and multiply by two. For example, a 20 lb puppy at 16 weeks would be estimated to reach approximately 40 lb as an adult. This formula provides a useful baseline, but it is subject to genetic variability, particularly in F1 generations where the puppy may unexpectedly favor the larger Bernese or smaller Poodle parent in its final development. Stokeshire prepares families for typical variation of 15 to 20 percent above or below the predicted weight. Try the Stokeshire Growth Calculator for a class-specific estimate.

Growth Plate Management

During the growth phase, the ends of the long bones contain soft cartilage growth plates that harden into solid bone as the dog reaches skeletal maturity. Until this process is complete, these plates are vulnerable to injury from high-impact or repetitive exercise. The standard veterinary guideline for protecting developing joints is five minutes of structured leash exercise per month of age, twice daily, until growth plates are confirmed closed by radiographic evaluation. High-impact activities (sustained running on hard surfaces, repetitive jumping, forced exercise on stairs) should be avoided in puppies and adolescents of all classes. This is especially critical in Standard and Ultra Bernedoodles, where the larger frame places greater mechanical stress on developing joints.

Nutrition and growth rate.

Large-class Bernedoodle puppies (Standard and Ultra) must grow at a steady, moderate rate. Rapid weight gain during the growth phase places excessive strain on developing bone and cartilage, which can exacerbate underlying dysplastic tendencies. Large-breed-specific puppy food formulations are designed to support slower, steadier growth with appropriate calcium-to-phosphorus ratios. Overfeeding during puppyhood, even with high-quality food, is one of the most common and preventable contributors to orthopedic problems in large-breed dogs. Your veterinarian can help establish an appropriate feeding schedule based on your puppy's class trajectory.

Choosing the Right Class

Which Bernedoodle Class Fits Your Household?

Class affects more than physical dimensions. It influences exercise requirements, grooming costs, veterinary expenses, living space needs, travel logistics, and lifespan. The right class depends on your household dynamics, living situation, activity level, and long-term commitment capacity. The right tier is rarely the one a family arrives wanting. It is the one their household actually accommodates.

The temperament, intelligence, and people-oriented nature of the Bernedoodle does not change meaningfully between classes. What changes is the physical management: space, food, grooming, veterinary cost, and exercise logistics. Choose the class that fits your household's reality, not the one that looks best in photos.


The Stokeshire Approach

Bernedoodle Classes at Stokeshire Designer Doodles

Stokeshire produces Bernedoodles across the full six-class ladder per the Stokeshire Doodle Size Standard. Every pairing is informed by Embark genetic testing on both parents, including coat genetics (RSPO2, KRT71, MC5R, FGF5) and Coefficient of Inbreeding (COI) calculation, with orthopedic evaluation (OFA or PennHIP) applied where appropriate to the lineage. COI management is how we deliver the documented benefits of hybrid vigor in practice (see the Bernedoodle Generations guide for the full position). Our breeding program meets the standards required for Good Dog certification, the third-party vetting program that audits health, welfare, and breeding practices.

Our Bernese dams are paired with Poodle studs selected for coat genetics, temperament, and class targeting. Toy Poodle studs produce Toy Bernedoodles through multigenerational lines. Miniature Poodle studs produce Mini Bernedoodles. Standard and Moyen Poodle lines produce Medium and Standard variants. The Petite tier is produced through our distinct Munchkin Bernedoodle program, which adds Cavalier King Charles Spaniel heritage to stabilize the smaller frame and soften temperament.

Ultra-range puppies occur selectively through Reverse F1B crosses where multigenerational Bernedoodle studs are bred back to Bernese dams. Stokeshire does not specifically breed for Ultra outcomes, and we do not promise Ultra results in any litter. Families seeking maximum-size dogs should plan for the variability that comes with hybrid genetics.

Size prediction is one of the most common questions families ask during our matching process. We use the 16-week doubling formula as a starting baseline and prepare every family for typical variation of 15 to 20 percent. Adult size is typical, not guaranteed. We are transparent about the reality that hybrid size outcomes are estimates, not promises. This honesty is part of the Stokeshire approach: clarity over hype, structure over persuasion.

Frequently Asked Questions

Bernedoodle Size FAQs

How big do Standard Bernedoodles get when fully grown?
Per the Stokeshire Doodle Size Standard, the Standard class typically matures at 51 lb and up (with most adults in the 70 to 90 lb range) and stands over 21 in at the withers. Males tend toward the upper end of the range, females toward the lower. Full skeletal maturity is usually reached between 18 and 24 months, though muscle mass may continue to develop beyond that point. Standard Bernedoodles result from crossing a Bernese Mountain Dog with a Standard Poodle. Adult size is typical, not guaranteed; individual puppies may finish 15 to 20 percent above or below the band.
How big do Mini Bernedoodles get?
Per the Stokeshire Doodle Size Standard, the Mini class typically matures at 26 to 35 lb and stands 14 to 17 in at the withers. Growth is usually complete by 10 to 14 months. Mini Bernedoodles result from crossing a Bernese Mountain Dog (or a Bernedoodle) with a Miniature Poodle. They offer a strong balance between Bernedoodle temperament and a manageable size that works well for most households, including apartments and urban living situations.
What is a Petite Bernedoodle and is it the same as a Mini?
No, Petite and Mini are distinct classes. Per the Stokeshire Doodle Size Standard, the Petite class typically matures at 16 to 25 lb and stands 12 to 15 in at the withers. The Mini class is larger (26 to 35 lb and 14 to 17 in). The Petite Bernedoodle is produced under the Stokeshire Munchkin Bernedoodle program, which adds Cavalier King Charles Spaniel heritage to stabilize the smaller frame and soften temperament for family-home placement. Petite is the program name; Munchkin is the line.
What is a Micro Bernedoodle?
"Micro Bernedoodle" is a marketing term, not a standardized class. Dogs marketed as Micro are typically Toy Bernedoodles at the lower end of the range, or Petite Bernedoodles labeled inaccurately. Stokeshire uses the six-class Stokeshire Doodle Size Standard: Toy, Petite, Mini, Medium, Standard, and Ultra. Extremely small dogs (under 10 lb) may face health challenges including fragile bone structure, dental crowding, and difficulty regulating body temperature. Stokeshire does not endorse extreme miniaturization and recommends families prioritize health testing and parent documentation over size-marketing terminology.
What is an Ultra Bernedoodle?
An Ultra Bernedoodle exceeds the Standard class, typically weighing 90 to 115 lb or more with a frame that leans heavily toward the Bernese Mountain Dog parent. Ultras are often produced through Reverse F1B crosses (approximately 75 percent Bernese and 25 percent Poodle). Ultra Bernedoodles carry the same temperament as other classes but require more space, more food, higher veterinary costs, and careful orthopedic management during the prolonged growth phase. Stokeshire does not specifically breed for Ultra outcomes; selecting for maximum size compromises structural soundness. Typical lifespan estimates of 10 to 13 years are shorter than smaller classes.
How can I predict my Bernedoodle puppy's adult size?
The most common method is the 16-week doubling formula: take the puppy's weight at 16 to 18 weeks and multiply by two for an estimated adult weight. This provides a useful baseline but is subject to genetic variability, particularly in F1 generations. Stokeshire prepares families for typical variation of 15 to 20 percent above or below the prediction. Parent size is the best predictor. The Poodle parent's size determines the general range, and the Bernese parent's genetics influence where within that range the puppy lands. Try the Stokeshire Growth Calculator for a class-specific estimate.
When do Bernedoodles stop growing?
Growth completion depends on class. Toy Bernedoodles often finish primary growth by 8 to 12 months. Petite typically finish by 10 to 12 months. Mini typically reach adult size by 10 to 14 months. Medium finish around 12 to 16 months. Standards and Ultras may continue developing skeletal density and muscle mass until 18 to 24 months. Growth plates (the soft cartilage at the ends of developing bones) close at different rates based on class and genetics. Until growth plates are confirmed closed, puppies should avoid high-impact exercise to prevent orthopedic injury.
Do smaller Bernedoodles live longer than larger ones?
Yes. This is consistent across virtually all canine breeds and hybrids. Toy and Petite Bernedoodles have estimated typical lifespans of 13 to 16 years, Mini and Medium classes 12 to 15 years, Standard 12 to 15 years, and Ultra 10 to 13 years. The primary driver is reduced cumulative physical stress on the cardiovascular and musculoskeletal systems. Smaller dogs also face lower risk of bloat, hip dysplasia, and certain cancers associated with larger body mass. Lifespan in any individual dog is also influenced by parent health testing, nutrition, weight management, and veterinary care.
How much exercise does each Bernedoodle class need?
Exercise needs scale with class, but all Bernedoodles require daily structured activity. Standard and Ultra Bernedoodles typically need 60 to 90 minutes per day, including walks, play, and mental stimulation. Medium Bernedoodles need approximately 45 to 75 minutes. Mini need 45 to 60 minutes. Petite and Toy need 30 to 45 minutes. Physical exercise alone is not sufficient for any class. The Poodle intelligence requires mental engagement (training sessions, puzzle toys, scent work) to prevent boredom-driven behaviors. For puppies of all classes, follow the five-minute rule: five minutes of structured exercise per month of age, twice daily, until growth plates close.
Which Bernedoodle class is best for apartment living?
Toy and Petite Bernedoodles are the most practical classes for apartment living due to their smaller footprint and lower exercise volume requirements. Petite Bernedoodles often conform to the 25 lb ceiling many luxury condos and co-ops enforce, though adult size is not guaranteed, and we recommend veterinary consultation before selecting a doodle for a building with a strict weight rule. Mini Bernedoodles can adapt to larger apartments with committed owners who provide daily structured outdoor exercise. Medium, Standard, and Ultra are generally not well-suited to apartment living. Their physical size, exercise demands, and space needs are better met in homes with yard access.
