Trying to solve the problem of dogs needing protection from air pollution threats has been an important topic for military leaders throughout the 20th century and into the current 21st century. The main concern for military leaders has been chemical toxins being used on the battle field which affect human soldiers and canine service animals. 

To solve the problem of chemical warfare on the battlefield for soldiers there have always been adaptive innovation for dogs serving in the military. How can we effectively care for the needs of these dogs in a toxic chemical warfare crisis?

Here is a collection of historical images of military service dogs wearing a variety of gas masks to protect them from these threats. Gas or chemical masks for dogs continues to be an area of innovation for military leaders around the world.
