MH and BPH: the Swedish system
for assessing dog behaviour
When a test stops predicting the future and starts describing the dog in front of you
Americans tried to predict a puppy's future.
The Swedes chose to describe the real personality of the adult dog.
And honestly, that changes everything. Traditional puppy tests try to answer a very ambitious question:
"What kind of dog will this puppy become?" The Swedish system asks a more modest—but also more accurate—question: "How does this dog react right now in specific, observable situations?"
Less crystal ball. More real dog.
MH: the original system—serious, demanding, and built for working dogs
MH (Mental Description Dog) was developed in Sweden to describe the behaviour of adult dogs, particularly working breeds.
The dog is guided through a series of standardised situations: meeting a stranger, playing, chasing a moving object, reacting to unexpected noises, sudden appearances of strange figures and, in some versions of the test, even gunshots.
In other words, it's quite an eventful afternoon. Probably not what a Toy Poodle had in mind when it was hoping for a cosy sofa, a warm blanket and a biscuit. That's why MH is fascinating from both a historical and scientific perspective, but it isn't always the most suitable assessment for small companion breeds. What did MH contribute?
A standardised way of evaluating fear, curiosity, playfulness, emotional recovery and reactions to unexpected events.
BPH: a more modern approach, closer to everyday life
Later came BPH (Behaviour and Personality Assessment in Dogs), also developed in Sweden.
The idea was similar, but with a broader approach that made the test suitable for many different breeds—not just working dogs.
BPH observes how a dog interacts with unfamiliar people, whether it enjoys playing, how it reacts to unusual objects, unexpected sounds and new situations, and above all, one particularly important trait: how quickly it recovers after being startled.
Because there's a big difference between a dog that gets frightened and then goes back to investigate... and one that decides the suspicious orange traffic cone is almost certainly working for a secret organisation.
The best part: there are no passes or failures
One of the greatest strengths of the Swedish system is that it doesn't try to label a dog as "good" or "bad." It simply describes what it observes. Nothing more... and nothing less. A dog may be highly social, not particularly playful, extremely curious, sensitive to noise, or quick to recover after a scare. These are not grades—they are pieces of a behavioural profile. For responsible breeding, that profile is incredibly valuable because it allows breeders to compare real behavioural data across individual dogs, bloodlines and breeds.
Why we find BPH so valuable
BPH reminds us of something that's easy to forget: a dog's personality can never be summed up in a single word.
It's not enough to say a dog is friendly, fearful or dominant. A dog can be cautious and curious at the same time. Sensitive, yet quick to recover. Reserved with strangers, but calm and emotionally stable. The Swedish system is designed to capture exactly these nuances.
And if you truly want to understand a dog, that's far more valuable than putting a neat little label on it and calling the job done.
What does BPH assess?
The dog follows a course made up of different everyday situations. There are no right or wrong answers.
The judges simply observe how the dog reacts, how long it takes to recover, and how it copes with each new experience.
1. Meeting a Stranger. A person the dog has never met before approaches, speaks to it and gently tries to pet it. The assessment focuses on: interest in people; confidence or caution around strangers; willingness to make social contact.
3. Food Motivation.
The dog is offered a food reward.
The assessment focuses on: interest in food;
speed of decision-making;
confidence when approaching the reward.
5. An Unexpected Noise. A sudden loud noise—usually a metallic one—is produced without warning.
The assessment focuses on: the dog's initial reaction;
its ability to recover; whether it voluntarily returns to investigate what caused the noise.
7. Different Walking Surfaces.
The dog is asked to walk across unusual surfaces, such as a tarp, a metal grate or an unstable platform.
The assessment focuses on:
confidence; self-assurance;
willingness to cope with something new.
2. Willingness to Play.
The dog is invited to play with a toy.
The assessment focuses on: interest in play;
initiative; ability to maintain interaction.
4. An Unexpected Surprise. Suddenly, an object or a strange figure appears that the dog was not expecting.
The assessment focuses on: the intensity of the startle response;
curiosity; whether the dog chooses to approach and investigate;
how quickly it regains its confidence.
6. A Stranger in Unusual Clothing.
A person wearing unusual clothing or with a striking appearance approaches the dog.
The assessment focuses on: caution; curiosity;
the dog's ability to adapt to an unfamiliar situation.
8. Sensitivity to Loud Sounds. In some versions of the BPH, the dog is exposed to a loud, sudden sound. The important point is not whether the dog is startled—most dogs are.
The assessment focuses on: how long the startle response lasts;
how quickly the dog regains its confidence;
whether it resumes exploring the environment naturally.
What Happens Next?
Like any scientific system, the BPH protocol is reviewed and updated regularly to incorporate new research in canine behaviour and improve the accuracy of its assessments. But the most interesting part begins after the course is over.
The dog has met strangers, played, been startled, investigated unusual objects and recovered from unexpected situations... What happens next? The judges don't simply declare the dog "pass" or "fail." Every response is recorded using a standardised protocol and combined into a behavioural profile. They evaluate the intensity of each reaction, how quickly the dog recovers, its curiosity, confidence, interest in people, willingness to play and readiness to explore unfamiliar situations. The result is neither a score nor an exam to pass or fail. It is an objective description of the dog's personality at that particular moment in its life.
And that's what makes BPH so different from many traditional temperament tests: it doesn't try to predict the future.
It simply aims to describe, as objectively as possible, the dog standing right in front of you.
