Thank you.
I was actually thinking about the efficacy of cadaver dogs on a landfill site, rather than H&S.
But thank you anyway. Now I know of an instance where a cadaver dog has been deployed. I live and learn.
My understanding is that it is not a popular deployment for the dogs and I think that is as much from the H&S point of view than efficacy.
Land fill sites are dangerous places to be and in the USA many of the cadaver dogs are privately owned and their owners are volunteers who do not go out of their way to put their dog at risk. I've read some discussion about boots being essential protection for the dogs' pads from broken glass etc.
The Canadian dog used by the Saskatoon officers was a police dog and the circumstances of the search might have been more favourable since the baby had been recently disposed of and the area of search might have been more feasible.
I don't think there is much these dogs find daunting as far as noses are concerned the problem arises when conveying what they know ... or don't ... to humans.
Doesn't your dog stand looking quizzically at you wondering why you're not getting what he's plainly telling you? mine does it all the time.
