Dhole Cuon alpinus numbers are declining rapidly in the wild. Therefore, it is very important to have vital captive populations. European zoos have the largest collection of captive Dholes in the world but breeding success varies greatly between zoos. One of the biggest problems is high pup mortality owing to inexperience of adults and inadequate housing. Within the context of a dissertation about Dholes in captivity, the effects of different husbandry parameters on reproduction in the species have been studied over 4 years. As a result of information reported in the dissertation a European Endangered Species Programme for Dholes was launched in 2006 by the European Association of Zoos and Aquaria. Since then, all new packs that have been formed and housed according to the latest scientific results have started to reproduce without any problems.
