This article is about a concept, not a mask.
This article has been written about something that is not a specific model of mask, but a concept relating to CBRN warfare or the engineering behind gas masks.
Animals have always been an essential part of a well-built army, from the knight in shining armor on his horse to the bomb sniffing dogs in Iraq and Afghanistan.
This was especially true during the trench warfare of WWI when gas attacks were common. Animals lived right by the soldiers in the
trenches, and they too needed protection from the poisonous gases seen in WWI. It wasn't until 196 when the last model of animal gas mask, the M6-12-8, was declared unfit and no longer used.
Protection for Canines Edit
During WWI, dogs were used for many purposes such as delivering messages, helping the wounded, scouting for enemies, or just simply comforting the soldiers. Despite this, the dog gas masks in WWI were very simplistic. They didn't even have a filter, making it somewhat like the PH hood.
An experimental dog gas mask, the E1R1, was made in 1926.
After a long break from development, several dog gas masks such as the E3R4, E6R2, E4R3, and E5R1 were made. Development stopped, and the M6-12-8 was declared obsolete in 1969. No further development has been made.
Protection for Pigeons Edit
Pigeons were used in WWI to deliver messages, so gas proof boxes were made to protect the birds while they were not flying.
Protection for Horses Edit
The last groups of cavalry were used during WWI. (Due to technological advances such as tanks, cavalry was rendered ineffective after WWI.)
Goggles were made for horses to protect their eyes during a chemical attack, but few soldiers put the goggles on their horses because they fogged up and prevented the horse from seeing well. WWI horses gas masks were very simple; the Armed Forces Museum describes them as, "...a flannelette bag with a corresponding canvas mouthpiece, which would be inserted into the horse’s mouth". The US Army M4 and M5 Horse Gas Masks were used during WWII.
