I don't and never have after many, many years. People often learn under the most tragic circumstances that what works some of the time doesn't work all of the time. They are terriers and all it takes is a rabbit or squirrel to come along to distract them and they're off and running. Some people can manage intensive training, but they are few and far between. There are so many predators as well, such as coyotes, big dogs running loose, hawks and owls that these little one's need protection from. Be very careful.
