Are you excited for National K9 Veterans Day this March 13, or are we barking up the wrong tree? Our little furry friends are already awesome as it is. But dogs who have been trained to serve our country are even more heroic. Plus, they look so cute and serious in their little uniforms. K9 dogs have been around ever since 1942, when an organization called Dogs for Defense was founded to train dogs to be sentries for supply depots. The program was approved by the U.S. Army in March 1942, the U.S. Army K9 Corps was founded on March 13, 1942, and the rest is history (literally). Get ready to celebrate America’s patriotic puppers!
