Have you forgotten what it said in the article I give you a link to already?
In the article it states that an alert by a cadaver dog needs to be taken with caution as someone could have left a bloody rag or a sanitary pad in the spot where the dog is alerting.
Isn't it strange how some don't like criticism of Grime yet are quick to laugh and mock at what other experts at training cadaver dogs say.
edited to add -
Unfortunately, in such a situation the trier of fact may easily be misled as to both the accuracy and precision of the dog's actions: Accuracy in the sense that the dog (depending upon its level of training) may be reacting to something other than residual scent from decomposed human tissue; precision in that the dog may be reacting correctly to the scent of decomposed human tissue, but imprecise in the sense that the dog is not differentiating between whose decomposed human tissue is giving the scent. Further, there may be legitimate reasons for the scent being there: someone may have been injured and left bloody clothing there, someone may have left a used sanitary napkin, etc. Our research demonstrates that residual scent from decomposed human tissue persists in a closed building for many months at levels sufficient to cause a trained dog to alert.
I do not know which link you refer to as there have been so many asserting this that or the other. In the end, they are for various cadaver dogs worldwide with different handlers, training and way of working, alerts, performance and results. We are talking about Eddie the EVRD dog and Mr Grime specifically has stated
Eddie was NOT trained for "live human" odours. He was trained on decomposing piglets initially and then mainly on human corpses.Decomposing teeth, nails, human tissue, blood ,urine, nappy pooh and all the rest, etc from live humans do not develop the same scent as corpse decomposition.
See his rogatory interview.
BTW There is no reference anywhere to
Eddie ever being a search and rescue dog. The above should show that. No mention of cross training either. No mention or record of deployment to find missing live people.
