On a list I'm on a trainer who calls himself "Captain Haggerty" said (to the effect) that "all military dogs should be trained to used gas masks."
I've only been in dogs for a short time, about 25 years, and I've never heard of a gas mask for dogs; so I called some people with vast experience in working K9's to get their take on this. One of them who must go unnamed just finished a classified study with an unnamed federal agency that has every possible implement used in the training and deployment of dogs and they didn't have any gas masks for them. Another couldn't stop laughing.
Thinking about a K-9 gas mask brought up some thoughts.
First there is a problem of getting the mask to seal around the dog's fur. Probably impossible without some sort of liquid or semi-liquid gel.
We know that dogs aren't susceptible to CN or CS gas. I've worked dogs in a pepper spray (OC) environment and know that it doesn't interfere significantly with their olfaction. Sometimes they sneeze a bit as they do from a direct application of the spray, but it doesn't affect them in the same way that it does most humans.
There is a problem with smoke agents because those are particulate in nature. They can actually stop olfaction, just as extreme conditions of dust can. But the dogs just sneeze or blow them out of their noses and go on.
Of course if the concentration of any of these is so high that oxygen is occluded there could be a problem, but a gas mask won't do anything for that problem. For that we need SCBA as worn by firefighter in smoke-filled environments.
If the mask is to protect against nuclear contaminants, the dog had better be in a lead-lined suit or the material that lands on his hair will take him out; they don't need to be inhaled to do damage. Just standing near some nuclear materials can cause death or injury from radiation sickness.
How about chemical agents? Things like mustard gas as might be seen in a military environment? Those also don't need to be inhaled, contact with the dog's skin or his pads will cause injury and possibly death.
Then there are the biologicals such as smallpox, anthrax, or botulinum. Neither of the first two affect dogs. The last might though. I guess the enemy could spray the area with the agent that causes kennel cough or parvo but I've never heard of any WMD programs developing those.
The very idea of using a gas mask seems to me to override some of the main reasons that we use K-9’s in the first place. The ability to scent, their ability to bite, their speed and agility. If the dog is wearing a mask that has filters that stop the influx of gas then the rafts and the associated gas also won't be passed, so the dog can't "sniff." If the mask makes biting possible it can't protect against the inhalation, via panting, of the materials the dog needs to be protected from. Anything you attach to the dog's head will surely cut down on his speed and agility.
But all of this being said, there may still be someone who knows something of canine gas masks or perhaps research done on the topic. Anyone? Anyone? Bueller?
