Dogs occupy diverse roles in society, from companions to working animals, making their behavioral study central to both science and welfare. With nearly 400 recognized breeds, scientists often compare dog behavior across breeds, but how these breeds are selected for studies can critically affect research outcomes.
Pongrácz and Dobos (2024) reviewed 97 behavioral studies and evaluated their methodology. They identified three common strategies for breed selection: convenience sampling, ancestry-based sampling, and functional sampling. Each method has strengths, but also limitations that may reduce the biological meaning of the results if not aligned with research goals.
Using the SWOT framework (Strengths, Weaknesses, Opportunities, Threats), the authors demonstrated when mismatches between breed choice and study design produced weak or misleading conclusions. For example, convenience sampling may bias results toward popular companion breeds, while ignoring working lineages with different behavioral profiles.
The review urges researchers to adopt ecologically valid approaches that consider the evolutionary, functional, and social contexts of different breeds. By doing so, future studies can generate findings that better inform both scientific understanding and canine welfare practices.
