The dog 2.0: Lessons learned from the past

Abstract

In recent years, concerns have been raised on the diversity, health and welfare of our (pedigree) dog population. Somewhat justified, the popular sire effect, population bottlenecks, the founder effect and inbreeding have left their marks on the dog as we know it. In order to improve the health and welfare of the canine population in general, individual breeding programs should adhere to the concept of ethical breeding (i.e. “the use of healthy animals true to their species in behaviour and looks, and when applicable, showing a sustainable performance”) when population-specific breeding goals are defined. Even though every population has its own problems, the approach to get to possible solution(s) is similar. The starting point will always be the identification of which (un)desirable pheno- and genotypes are segregating and what their prevalence is, followed by an evaluation of the genetic diversity. Based on that information and, when applicable, additional criteria like breed standards, breeding goals can be defined. It is of critical importance that these goals are put forward with a long term vision in mind and with consensus from the stakeholders to ensure collaboration. Upon prioritization of the most important goals, when necessary with the help of specifically developed tools, the final step is choosing the most optimal combination of breeding strategies. This paper aims to provide a stepwise approach to identify and tackle population-specific problems encountered in breeding programs.
