I know they make some rubber bludgeon tips meant for small game. Aim for a meaty muscle so that there is lower risk of impact injury, and so that you don't kill or maim by hitting it in the head. I imagine it would hurt like hell, but wouldn't think it would do any real damage. For some dogs, it is nothing to roam over several miles from their home in the course of a day.

God shall never burden us with more than we are capable of carrying. Remember, a walk in the park for some, may be a seemingly insurmountable task. No one can wear another's shoes. The reward is not to be found in this life, but the next. Amen.
