Estimation of Owned and Street Dog Population by Quesionnire Survey and Mark-Recapture Method in Three Urban Areas: Bishoftu, Dukem and Modjo Towns

Abstract

The understanding of the structure of free-roaming and owning dog population’s estimation is of extreme importance for the planning and monitoring of dog population control strategies, animal welfare and health. The methods used to estimate the abundance of this group of dogs are more complex than the ones used with domiciled owned dogs. We point to enhancements necessary for the implementation of the studies and to potential updates and revisions to the recommendations of the World Health Organization with respect to the estimation of free-ranging and owning dog populations. Rabies is a fatal viral disease of animals and people. People usually infected via bites from an infected animal (e.g. dog). Post Exposure Prophylaxis (PEP) has to initiate immediately after bite wounds of suspected rabid animals in order to avoid fatalities. The situation of rabies poorly known in Ethiopia. Questionnaire survey was conducted in selected blocks in Dukem, Bishoftu and Modjo towns in order to capture information on dog population size estimates using mark-resight surveys has provided useful baseline data for understanding the population dynamics of dogs at the study sites. Mark-resight surveys provide useful information for designing and managing the logistics of dog vaccination or assessing vaccination coverage and for evaluating the impact of neutering programs on the size and structure of dogs’ populations over time. As part of a dog born zoonosis disease risk assessment project, surveys conducted to estimate the size of the dog population and to describe dog management practices of households belonging to different ethnic groups. A markedrecapture method employed and the number of unowned dogs estimated. A total of 599 dog owning households and 276 non-dog household interviewed from at selected 19 blocks at study sites. Owned dogs were more likely male, local breed and for the purpose of used to guard. These households kept their dogs either fully restricted, semi and free roaming but full restriction have reported only at the higher percentage of the total dog households. By counted method, study the ownerless dogs higher than owning and semi-restricted dogs.
