4.1 Diagram illustrating the overlap between owned and free-roaming populations of dogs. The size of each compartment relates to the size of the respective populations, which varies greatly depending on the local situation. Note that some fully confined animals are not responsibly owned, and some unconfined animals may be responsibly owned. Shelter animals are, by definition, confined and may be responsibly or irresponsibly owned.

4.10 Geographical strategy for work. Map data: Google, Google Maps 2015; boundaries created using Google My Maps. (a) Divide the area of work into workable regions using maps (2–3 km). (b) Concentrate neutering/vaccination of dogs in a single or limited number of regions. Once staff suspect that the desired proportion of dogs has been neutered/vaccinated, or no more dogs can be caught, conduct a dog sight survey of the region counting the number of neutered/unneutered dogs. Calculate the percentage of neutered dogs by region and repeat capture of dogs from that area if below the desired threshold. (c) Repeat this process of capture–survey until the desired percentage of dogs has been neutered/vaccinated, then move to the next region. (d) Continue in this manner until all regions are complete to the desired percentage. Grey = incomplete; Pink = active; Green = complete. (© Mission Rabies)
