Research & Methodology

Last updated: August 2026

DogCompatibility is built to help people look past appearance and popularity and understand what living with a particular breed is actually like. This page explains, in plain terms, where our information comes from and how our matching works.

Where our information comes from

Breed information and compatibility insights are synthesized from a network of reputable, publicly recognized types of sources, including:

• Established breed standards and descriptions maintained by recognized canine organizations.
• Veterinary references and canine-health resources.
• Peer-reviewed research on canine behavior, temperament, and welfare.
• Widely accepted, general knowledge about breed characteristics and care.

We combine and interpret these source types to describe general tendencies. We present this as our own synthesis rather than reproducing any single source verbatim.

Our compatibility framework

Our matching uses an original compatibility framework we developed. In simple terms, it works like this:

• You answer questions about your home, schedule, activity level, household, experience, and preferences.
• We describe each breed across a consistent set of compatibility factors, then compare your answers with those factors to surface where a match tends to be strong — and, just as importantly, where it may be difficult.

We deliberately show trade-offs, not just a single score. The goal is understanding, not a leaderboard, and rankings are never influenced by payment or sponsorship.

The 33 compatibility factors

Each breed is profiled across 33 compatibility factors that span the areas that matter most in day-to-day life with a dog:

• Energy & activity: energy level, exercise requirement, mental-stimulation need, and playfulness.
• Training & temperament: trainability, intelligence, stubbornness, sensitivity, protective instinct, and sociability with strangers.
• Household & social fit: compatibility with children (including young children), other dogs, cats, and general family-pet and affection fit.
• Home & lifestyle: apartment fit, adaptability, tolerance for time alone, and suitability for novice and senior owners.
• Care & upkeep: shedding level, grooming effort, drooling tendency, barking level, size, and estimated annual cost.
• Climate & health: heat and cold tolerance, hot- and cold-climate fit, working-role fit, and an overall health-risk consideration.

Every breed is scored on the same standardized set of factors using the same scales, so breeds can be compared on a consistent, like-for-like basis rather than on ad-hoc descriptions.

What the scores mean

A compatibility score represents relative fit between your answers and a breed’s typical profile — how well the breed tends to line up with what you described. It is not a prediction of how a specific dog will behave, and it is not a quality ranking of the breed itself.

Alongside matches we also show a Research Confidence indicator. This reflects the strength and consistency of the information available for a breed — how well-documented and widely agreed-upon its typical characteristics are — rather than mathematical precision or certainty about any individual dog.

Individual dogs vary

Every breed description reflects general tendencies, not guarantees. Any individual dog can differ significantly from its breed’s typical profile depending on genetics, early upbringing, training, socialization, health, and environment. A strong “match” is a starting point for research and conversation, not a promise about a specific animal.

Decision support, not a guarantee

DogCompatibility is a decision-support tool. It is intended to inform and complement — not replace — your own research and conversations with shelters, breeders, veterinarians, and trainers. It does not provide veterinary, medical, or other professional advice, and it does not guarantee any particular outcome.

Keeping it current

We periodically review and refine our breed descriptions and framework as our understanding improves. This page will be updated to reflect material changes to our approach.
