Regulations, Field Manuals, bulletins, policy memos and other documents pertaining to the military working dog program can be found in the AKO folder at the link. The library is not yet entirely inclusive or exhaustive and will be updated frequently.
Note: The MWD Handbook is still undergoing revision. We are looking to add more information regarding blast injury and behavior changes related to deployment. Unfortunately, new version is not projected to be published until June 2012.
