I see that story's in the news again about dogs being able to detect cancer by smell.
I know it sounds like an April 1st story, but I actually think there is something in it.
When I was poorly with that thing growing on my right kidney, whenever I popped to the pub up the road, one of the doggies who lived there used to come sit with me ans pay me lots of attention.
After the tumour had been removed and I was well enough to go back up the pub, the little tyke had nothing to do with me.
Exactly what is is a dog's nose can detect, I have no idea, but from personal experience, I can't dismiss is as bunkum.
