Population dynamics of dogs in the Mnisi area, Hluvukani, South Africa

Abstract

The aim of this study is to determine how the dog population is formed in Hluvukani, South Africa. It is part of a baseline pilot study to see whether a temporary sterilization can be of use to stabilize or decrease the Hluvukani dog population. A lower turnover rate of the population will help to achieve a better vaccination grade against rabies. The ultimate goal is to eradicate rabies, to prevent human victims. During several rounds of house to house visits, research information about the dog population has been collected. People were questioned about their dogs and their willingness for female dog contraception. In 2011 the dog population consisted of 799 dogs. In 2013 it has increased to 870 dogs. The population increased with 5,9% over 12 months. Despite the free castrating campaigns only 10 female castrated dogs were found in 2011 and 12 female castrated dogs in 2013. The density of dogs in 2011 was 77/km2 and 83,9/km2 in 2013. A male:female ratio of 1,32 (2011) and 1,47 (2013) was found. To determine the population turnover rate more research is needed. The best method will be a Leslie matrix of the population. With the Leslie matrix it will be possible to run an computer stimulation to see the effect of Gonacon™ injection in female dogs on the dog population in Hluvukani.
