Is it practical or possible to give a dog a test that will predict how he is likely to behave in real life situations

Is it practical or even possible to give a dog a test that will predict how he is likely to behave in real life situations? Is there a need for such a test, particularly regarding whether he is likely to get into harmful conflicts with people? This new entry in our research library is our attempt to summarize what the best science to date has to say about these questions. We report here on the work of researchers of varying backgrounds and expertise examining behavior evaluations from different viewpoints. The picture that is emerging is one that reveals behavior evaluations as too often unreliable and invalid. Moreover, a recent statistical analysis (Patronek & Bradley, 2016)[1] demonstrates that even in the very unlikely event that test validity reached standards that would be considered high in human medical diagnostic tests, the outcome would be unacceptable for dogs, among whom dangerous biting behavior is rare. So many false positives would result that the test would be no better than flipping a coin. Considering the consequences – passing or failing such a test can mean the difference between a dog in a shelter being made available for adoption or being euthanized – the welfare issue is clear.

Rather than a traditional literature review, our work here is a critical analysis of the most commonly cited and the most methodologically strong attempts to answer the key questions. Where works exist that can be considered seminal, these are included. For a description of just how wrong uncritical uses of sources, particularly secondary sources, can go, consider Patronek, Bradley, & Cleary’s “Who is Minding the Bibliography?” in a 2016 issue of the Journal of Veterinary Behavior [2,3]. We hope you’ll take a look at this new version of a literature review on a topic with profound implications for dogs in shelters and beyond.
