Jag skulle egentligen säga en kropp luktar lik relativt omedelbart som den dör, vilket en likhund kan känna. Så hade han inte sänkt ubåten hade troligen en likhund känt liklukt i ubåten.

Stämmer inte.
Nedan, test där vissa organ fortfarande fungerar. Men är alla organ "döda" blir det annorlunda.
"Several squares had been placed beneath a clothed corpse within three hours of death, when some organs and many cells of the human body are still functioning. Over the next month, the dogs did hundreds of trials in which they signalled the contaminated square with 98 per cent accuracy, falling to 94 per cent when the square had been in contact with the corpse for only two minutes. The research concluded that cadaver dogs were an "outstanding tool" for crime-scene investigation."
Sedan frågan om hur länge en yta måste exponeras:
" In a study published last year, the forensic pathologist Lars Oesterhelweg, then at the University of Bern in Switzerland, and colleagues tested the ability of three Hamburg State Police cadaver dogs to pick out – of a line-up of six new carpet squares – the one that had been exposed for no more than 10 minutes to a recently deceased person."

Sen då frågan hur snabbt en död kropp börjar utsöndra det speciella ämne decaverine som hundarna kan känna av. Decaverine uppstår när "decomposition" börjar.
"Decomposition begins several minutes after death, with a process called autolysis, or self-digestion."

Så, det är klart att det blir svårare tidigt, men troligen inte omöjligt.
