Unless there is some reason you can't use one, I would put a fence charger on my fence. They are non-lethal, and can be turned off when not needed.
Animals quickly learn to stay away from them ( as do people)
If you are in an area where there are people walking around your fence, this is probably not going to be a solution to your problem, as you wouldn't want anyone to get shocked.(Unless they were undercover PETA members)
