The common bear spray has a range of 15-30 feet (depending on variant), but may come with restrictions re: use against humans.

Just some thoughts.

Be very careful with stun guns. Youngest son bought one home from a local "Trade Center" where merchants rent tables and sell and these were sold openly.
However, Mich. law considers the carry of one, absent LEOs, COs, etc., to be a Felony.
