Just like the human law enforcement personnel he works next to, Montgomery County Sheriff’s Office K9 Flex is a potential target for criminals.   Now like the humans wearing the badge, Flex can spring into action with some protection. Non profit organization Vested Interest in K-9s has provided Flex a bullet and stab protective vest.   The passion for protecting police dogs reaches far beyond Mid-Illinois. The sponsor of K9 Flex’s vest comes from the capital city of Maryland. Deborah Kostakos of Annapolis is the sponor and the vest should arrive in mid to late May.    The potentially lifesaving body armor for four-legged K9 officers is U.S. made, custom fitted, and certified. Vested Interest in K9s, Inc. accepts tax-deductible contributions in any amount, while a single donation of $960 will sponsor one vest. Each vest has a value of $1,744-$2,283, weighs an average of 4-5 lb., and comes with a five-year warranty. For more information, or to learn about volunteer opportunities, please call 508-824-6978. Vested Interest in K9s, Inc. provides information, lists events, and accepts donations at www.vik9s.org, or you may mail your contribution to P.O. Box 9, East Taunton, MA 02718.
