Not sure, I no I talked with a guy that handles and owns a arson dog, and their working time is about 5-7 years. Those dogs get a piece of food everytime they smell accelerant. Yes that's right 1 piece of food everytime they smell gas. So that dog has to sniff that to eat every day, however many times it takes to get it's needed food intake. This dog sat when it "HIT". Your dog duck swimming across the marsh that abruptly sits because of out board residue on the water, may be a little rough to get through.
The amount of dogs that get washed out of the arson program is only second to seeing eye dog training. While I always say we don't give them near enough credit for how smart they are, I think this would be tough to pull off. It takes a ton of time just to make a good finished waterfowl dog. IMO
