Pigs vs. dogs as truffle-hunters
"According to the few truffle hunters I’ve talked to, sows are actually
better truffle hunters than dogs, but dogs can be more easily trained
not to eat the truffle they find. Prodan told me the reason for porcine
superiority is that the truffle contains the steroidal pheromone
androstenone, which also happens to be produced in the saliva of male
pigs. Thus, female pigs, particularly when they’re in heat, go hog-wild
when they pick up the scent of a truffle."
