How the quiz produces a ranking
The quiz opens by asking what you want a dog for — family companion, working dog, sport partner, guarding or assistance. That answer selects a branch, and only the questions relevant to that branch are asked. A run is between 11 and 22 questions depending on which branch you take and which follow-ups your answers trigger.
Your answers become weights across the traits each breed is rated on: energy, size, trainability, friendliness, grooming, shedding, barking, child-friendliness, protectiveness, independence, adaptability and prey drive, plus typical lifespan. Every one of the 321 breeds is then scored against those weights and the list is ranked. The scoring is deterministic: the same answers always produce the same ranking. Nothing is randomised, and no breed is promoted for commercial reasons — there is nothing sold on this site.
What the match percentage means — and what it does not
The percentage is relative to your best match, not an absolute measure of fit. The top breed on your list is always shown as 100%, because every other score is expressed as a proportion of it. A second-place breed at 92% is 92% as close to your stated profile as the first — it is not a 92% probability of success, not an accuracy figure, and not a claim that the dog will suit you.
Read the ordering, not the number. The gap between positions tells you more than the value: a shortlist where the top five sit within a few points means several breeds fit you similarly well, and the choice is genuinely yours.
Where the breed ratings come from
The trait ratings behind every score were written in-house as editorial judgements, drawing on published breed descriptions and breed-standard temperament language. They are not taken from a registry dataset, a peer-reviewed study or a veterinary database, and they are not the output of any measurement. Our own database records their confidence level as insufficient, and we would rather print that here than imply a precision we do not have.
Practically: the ratings are reliable enough to separate a Great Dane from a Chihuahua on space needs, or a Border Collie from a Basset Hound on exercise. They are not reliable enough to split two similar breeds by a single point. Treat a one-step difference on any trait as noise.
Improving this is the main open piece of work on the site. If you have expertise in a breed and something here is wrong, tell us: support@doggyq.com.
What breed-level ratings can never tell you
Every rating on this site describes a tendency across a breed, not a promise about a dog. Within any breed, individual dogs vary more than the breeds differ from each other on most traits. Upbringing, training, health, socialisation and simple individual temperament routinely outweigh breed. A calm Border Collie and a hyperactive Basset Hound both exist.
So the quiz narrows the field. It does not pick your dog. Meet the individual animal, talk to whoever raised it, and weigh what you see in front of you above anything on this page.
How the ranked lists are scored
The lists under best dogs for… use the same ratings. Each list defines which traits matter for that situation and scores every breed on them — the apartment list weights size, energy and barking; the low-shedding list weights coat type and shedding. Some lists also apply a qualifying filter: a breed cannot appear on a guarding list without a genuine guarding instinct, and designer crossbreeds are excluded from working-dog lists where they would otherwise inherit their parents' scores.
Where scores tie — and they often do, because the scales are coarse — the more widely known breed is listed first. That is a readability choice, not a claim that it fits better.
Who has reviewed this
No veterinarian, behaviourist or breed expert has reviewed this site. We say so plainly because the alternative is to imply a review that has not happened. If that changes, this page will name the reviewer, their credentials and what they actually checked.

Find your perfect matchFrequently asked questions
- What does the DoggyQ match percentage mean?
- It is relative to your top match, which is always shown as 100%. A breed at 90% is 90% as close to your stated profile as your first match — it is not a probability, an accuracy figure or a guarantee of fit. Read the ordering rather than the number.
- Where does DoggyQ get its breed data?
- The trait ratings were written in-house as editorial judgements based on published breed descriptions and breed-standard temperament language. They are not drawn from a registry dataset, a study or a veterinary database. Breed photographs come from Wikimedia Commons under their stated licences, with the photographer credited on each page.
- Has a vet reviewed DoggyQ?
- No. No veterinarian, behaviourist or breed expert has reviewed this site. If that changes we will name the reviewer and their credentials on the methodology page.
- Can a breed quiz actually predict the right dog for me?
- No, and this one does not claim to. Breed ratings describe tendencies across a breed, while individual dogs vary more within a breed than breeds differ from each other on most traits. The quiz narrows a field of hundreds to a handful worth investigating; meeting the individual dog decides the rest.
