Monroe's Police K9 has been outfitted with a bullet and stab protective vest. For every 15 vests purchased through the non-profit organization "Vested Interest in K9s", one free vest is awarded. K9 Murphy's new vest has a five-year warranty, and weighs 4 to 5 pounds. The non-profit was established in 2009 to assist law enforcement agencies with this potentially lifesaving body armor for their four-legged K9 officers. "Vested Interest in K9s" has provided over 2,300 protective vests, in 50 states at a cost of over $1.9 million. All vests are custom made in Michigan.
