A multifunction dog training collar for pet behavior modification is provided. The collar may operate in multiple modes including a remote training mode, a confinement mode, and an anti-bark mode. In the remote training mode, a dog trainer may use a hand-held remote to apply a stimulus to correct misbehavior. In the confinement mode, the collar will apply a stimulus when the dog approaches or crosses a pre-defined boundary. In the anti-bark mode, the collar will apply a stimulus when the dog barks.
