It is, indeed, simple pathfinder.

Why do you suppose Grime was asked, in his rogatory interview whether Eddie would react to blood?

The ones asking the questions are not dog experts.

"The dog EVRD is trained using whole and disintegrated material, blood, bone tissue, teeth, etc. and decomposed cross-contaminants. The dog will recognize all or parts of a human cadaver. He is not trained for 'live' human odours; no trained dog will recognize the smell of 'fresh blood'. They find, however, and give the alert for dried blood from a live human being."

Same for Morse, Buster, all cadaver dogs. Eddie is no different.

You are aware that dead human beings don't bleed?

They very well could bleed while they are dying.

They certainly do immediately after death.

And if the lower part of the cadavar where the blood has settled, has been damaged as it is moved etc., it will bleed Cadavar blood according to one article I read.

So Cadavars do sometimes lose blood.  A cadavar dog will alert to this, even if the blood has been cleaned up.

That sounds spot on the mark Sadie.

No cadaver dogs alert to fresh blood scent. They all alert to dried blood.

To get any dog to alert to anything, you have to introduce the dog to the scent you want the dog to alert to and reward the dog for alerting.

If you don't want a dog to alert to that scent, you simply skip the step of introducing the dog to the scent and rewarding the dog for alerting to it.

Then the dog won't.

Having two dogs that both alert to the same scent is, well, plain barking.

Always the weak link in the Eddie-and-Keela combination.

There was always a weak link with Eddie.  He was trained in one way, and then expected to understand another.  And Martin Grime did know this.

But even properly trained Cadaver Dogs will alert to a weaker scent if there is nothing else.

This, I think, is a useful link.

It seems Australia has followed the American lead in allowing an American-style 'bodyfarm'.

http://www.dogforceaustralia.com.au/police-dog-handler-detection/

Its course on cadaver dog-training lists these components of training:

Quote
Cadaver (Human Remains) Detection Dogs will be fully accredited on the following odours:

human tissue (in varying states of decomposition)
blood
bone

Note that human tissue, bone and blood are all listed separately.

The process of teaching a dog to react to, distinct from detecting (which it does, automatically and instinctively without training) the odour of blood is a separate and distinct step that the dog must be taught.

If you don't teach the dog that step, then, while the dog will of course, still detect the scent of blood, the dog won't react to it unless it is mixed with something else the dog is taught to react to.

Email that to an expert and post their response. "A cadaver dog won't alert to blood on its own?" Let's see their reply. I can't wait.

Dogs trained to react to blood will do so.

But not otherwise.

Ditto dogs trained to react to drugs.

Or trained to react to explosives.

Or trained  to react to cancer cells in humans.

But in each of the above-listed cases, not otherwise.
