Sadie, sorry but that post is rubbish. Martin Grime was explicit that Eddie wouldn't alert to cooked pork. The alert was not up the wall but in the area of the wardrobe. You are making excuses by using some hypothetical ashes and pyjamas. Keela had an excellent nose for detecting the smallest drop of blood. All in all I have to disagree with everything you have posted.
From Martin Grime.
"'Eddie' The Enhanced Victim Recovery Dog (E.V.R.D.) will search for and
locate human remains and body fluids including blood in any environment or
terrain. The initial training of the dog was conducted using human blood and
stil born decomposing piglets. The importance of this is that the dog is
introduced to the scent of a decomposing body NOT FOODSTUFF. This
ensures that the dog disregards the 'bacon sandwich' and 'kebab' etc that is
ever present in the background environment. Therefore the dog would
remain efficient searching for a cadaver in a café where the clientele were sat
eating bacon sandwiches. He has additionally trained exclusively using
human remains in the U.S.A. in association with the F.B.I. The enhanced
training of the dog has also involved the use of collection of 'cadaver scent'
odor from human corpses using remote technical equipment which does not
contact the subject. This method is comparable to the simulation of cross
contamination. It does however differ in that the remote scent samples
recovery does not involve subject matter and therefore is a 'pure' scent
sample. The dog has since initial training gained considerable experience in
successfully operationally locating human remains and evidential forensic
material."
Feel a song coming on.
