Edidie is not sent in to search for blood but remnant cadaver scent (obviously in places where no body is there) ......he is a cadaver dog first and foremost even if he can smell blood......if he alerts then the blood dog is sent in to find forensics ie blood, that might shed light in a case, simple as that, no need to complicate matters
There's nothing complicated about it Red. Both dogs could detect blood, which is why Grime did not bother to send Keela in at all - if Eddie had made no alerts. Grime knew there was no need to send her in because if any blood
had been present Eddie would have detected it.
Eddie was trained to detect cadaverscent and blood. But there was no way he could tell his handler which one of the two odours he was alerting to - which is why Grime always sent Keela in afterwards.
Amaral's description of Eddie as only alerting to cadaverscent is completely wrong and therefore misleading.
