Rabies is one of the most dreadful infectious diseases that could be transmitted from<br />

animals to humans through saliva of the infected animals. In this project, we consider a<br />

mathematical model to examine the transmission dynamics of rabies virus among dogs<br />

and from dog to human populations. This model will assist in predicting the spread of<br />

rabies in both human and dog populations. The basic reproduction number of the system<br />

is derived using the next generation matrix approach. The existence of disease free and<br />

endemic equilibria is studied and its stability is analyzed. The disease-free equilibrium is<br />

locally stable whenever the basic reproduction number R 0 < 1. Otherwise, the endemic<br />

equilibrium achieves local stability. Moreover, numerical simulations are performed to<br />

depict the dynamics of disease transmission. We find that by increasing the immunization<br />

rate and decreasing the annual dog birth rate, there is a possibility that rabies will die off.<br />
