I haven't witnessed any sadness or depression in a cadaver dog after they locate human remains, they're trained to detect body tissue and/or fluids of the deceased and necrosis is present and they don't affiliate the scent of the dead with the living, in other words they recognize the living by their scent which is a totally different scent of course but they are not able to rationalize that a human being smells one way when alive and another way when deceased, to them the deceased are not connected to the living in their mind. Now if they were to come into contact with a deceased person that they had been close to while the person was alive, they may react differently. The dogs are praised and rewarded when they do a good job, so for them it is a positive experience. I don't think that's an odd question though, Sarah, I've actually been asked that several times.
