Highlight:
It's fascinating: dogs' noses represent some of the most sophisticated spectrographic analysis equipment available on the planet. Now dogs have been trained to actually "sniff out" bladder cancer by smelling the urine of patients....
Skin, bladder, lung cancers - dogs have been trained to find each. I saw one study where they could dtect early signs of arthritis too.

But before you can up your doctor, maybe your knee just smelled good that night. My current cat likes my deodorant - she'll climb up and start licking my armpits if she gets a chance.
