I told you that dogs are way, way better at smelling things than people are? Well, even though everybody knows this is true, nobody knows exactly how much better dogs can smell stuff than humans can. One of my in-depth research sources said that a dog's sense of smell is 10,000 times better than a person's, and another in-depth source said it is 100,000 times better! So since there is a huge gap between these two numbers, I think this means that people just really can't understand at all what it's like to be a dog and to smell so many interesting things all the time.
But anyway, my point is that because dogs can smell so well, they can do all sorts of important work for people if they are just trained to know what people want them to do. So for instance, dogs can sniff out drugs and bombs and dead people and bedbugs, like I've already told you in some of my other blogs.
Marine was so good at this that she got the right answer 95 percent of the time with the breath samples, and when she sniffed poop samples, she was right 98 percent of the time. In the past, other dogs have been taught to identify cancer of the skin, bladder, lung, breast, and ovaries. And mostly they just do this by sniffing breath samples or urine samples or skin lesions.
I thought that maybe this discovery about how good dogs are at sniffing out cancer would mean that lots of dogs could get jobs in doctors' offices, which would help the canine unemployment situation. And also that dogs would have a bunch of money to buy yummy dog food and treats with. But it turns out that the scientists don't want to pay what it would cost to train that many dogs to have cancer-sniffing jobs. Instead, they want to build some kind of machine that can sniff cancer just like a dog can. Well, I say good luck with that!
