My WIP hero is a retired Navy SEAL who brought home his trained war dog. I love doing research while writing. Here is a misconception about military trained war dogs. Yes, they are trained to bite, and this can result in missing teeth. They only bite on command. Replacing injured teeth with titanium (at a cost between $600-$2,000/tooth) is one way to help a dog continue its service. War dogs wear tactical body armor. A dog’s assault suit costs $89,000 with wireless cameras, radio communications. Infrared night cameras relay visuals from as far as a thousand yards away. Speakers are included so that handlers can communicate with the dogs! Approximately three thousand retired war dogs are adopted annually.
