Did a similar thing where I had a neighbor who raised dobermans and rottweilers - it's a bit difficult to code with 8 or 9 large dogs barking in the yard outside your window. Set up an amp and speakers that would pump out ultrasonic noise when it heard the barking, sending them running to the other side of their house.
