Progress in Eliminating One-Year Dog Studies for the Safety Assessment of Pesticides

Abstract

We reviewed six key peer-reviewed publications that assessed the need for one-year studies of pesticide toxicity in dogs. Each of the six papers took a different approach to comparing the value of one-year studies relative to three-month studies, and despite the adoption of different databases and approaches, each study reached the same conclusion: the recommended limit to the testing of pesticide toxicity in dogs should be three months.

Therefore, the present review supports the conclusion that the routine inclusion of a one-year dog study should not be a mandatory requirement for the safety assessment of pesticides, since it is scientifically no longer justifiable. We recommend that the OECD should adapt a harmonized approach that is in line with the legislation in Europe and the USA.
