K9 Thor (vcsok9thor) is excited to say Happy National K9 Veterans Day! Each year, on March 13, the service of American military and working dogs throughout history is honored and commemorated. K9 working dogs have been around 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 US Army and, on March 13, 1942, the US Army K9 Corps was established. #K9 #vcsok9thor #vcsheriff #nationalk9veteransday #workingdog
