'ere we go again. It was all Amaral's fault. No back up to the statement whatever.
It's more than obvious that Amaral didn't understand them. He was under the impression that Eddie only alerted to dead bodies and had no idea that he also alerted to blood from living people. The following extract from his book proves that.
He's got the facts completely the wrong way round - as it is only when Eddie alerts and Keela doesn't that Grime deduces that blood may not be the reason for the alert.

Eddie is always the first to be brought onto a site. Once he has discerned the odour that he knows so well, it's Keela's turn to go into action, on the lookout for the slightest whiff of blood.
The simultaneous presence of the two elements in a given place - blood and cadaver odours - is taken to indicate that a body has been there and that it's probably there that the death occurred.Unquote
Both dogs alerted to the keyfob. Both dogs alert to blood from a living person. The forensic tests showed that it was Gerry's DNA that was present.
Amaral's description of how the dogs 'worked' in his book is simply not true.
