Stray Dog Population Control in Campus San Joaquín of the PUC University. An Ethically and Technically Feasibly Way

Through a stochastic simulation of the population of stray dogs in the main Campus of the Pontificia Universidad Católica de Chile, the impact of adoption and sterilization policies is analyzed. The data used as border conditions were collected with 3 yearly census. The model was contrasted with the effect of the policies taken by a local organization, validating the model. The main results of the sensibility analysis is that without action the population would be 1 dog/acre and if the sterilizing and adoption policies were raised in a 25% and 50% respectively, the population would be reduced to 0,6 dogs/acre and that if the policies were cancelled, the population would return to its original level in less than 12 months. It should be noted that in Santiago de Chile there are about 500.000 stray dogs and is urgent to solve this socio-environmental problem and that ethical ways are technically feasible.
