The data were analysed to determine mean proportions,the Odds ratio was used as the measure of association between outcome variable and independent one was significant at P < 0.05 and logistic regression was used for modeling . STATA13 software was used for analysis of the data.
Results Three hundred and sixty households enrolled had a population of 498 dogs with 48.2% (n=240) dogs vaccinated against rabies within the last 12 month. The vaccination of dogs at household level were statistically significantly associated with history of being exposed to rabies (OR=3.6, 95% CI 1.29 - 10.05), Education,were by secondary education and above (OR=8.72, 95% CI 2.6 -29.5) , Proper feeding of dog (OR=4.0 95% CI 2.09-5.91), Availability of vaccine (OR=1.72 95% CI 1.08-2.75), Availability of Vet/Field officer (OR=9.64 95% CI 1.28-72.64) and Sex of dogs were more males were vaccinated than females (OR=1.5 95% CI 1.03-5.91).
