Keela was directed to search the master bedroom, and found no traces of blood other than a drawer containing women’s underwear. Grime noted that isn’t uncommon because of the scent of menstrual blood.

Interesting.
Morse also reacted in the bedroom as noted by Martin Grime.
“As soon as the dog entered the bedroom, he exhibited behavioural changes.”
http://loudounnow.com/2016/06/02/day-9-of-castillo-murder-trial-hones-in-on-phone-records/There are stringent rules re independent testing which allows dogs' evidence to be presented in American courts which Morse met and indeed exceeded.

At trial, FBI Canine Program Manager Rex Stockham testified as an expert in forensic canine operation. Stockham testified about the process of training and testing victim recovery dogs. Stockham's protocol called for regular single-and double-blind testing of dogs throughout their working lives. Stockham's program had three full-time handlers in its program, including Martin Grime. Stockham testified that he had tested Morse and Keela, Grime's dogs, and that both dogs had accuracy ratings in the high 90 percent range. Stockham testified that dogs have been able to smell the odor of decomposition as soon as 2 hours after a victim's death, or years after a victim's burial.

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.

The dogs do not get confused. They transmit a behavioural response inspired by the recognition of the odour for which they were trained.
http://www.mccannpjfiles.co.uk/PJ/MARTIN_GRIMES_RIGATORY.htmAccording to the handler it isn't considered unusual for the dog trained only to alert to blood to alert as in this case to a knicker drawer. I would presume the underwear therein had been laundered but was contaminated still, although not visible to the human eye or nose.
Why would it be strange or unusual for the VRD to react to scents it was trained to recognise?
Particularly in bedrooms where it would be possible for areas to be contaminated by bodily secretions such as semen to be recognised by the VRD but which is outside the parameters of the CSI trained only to blood.
