What is all this hype about dogs smelling and detecting cancer? And even at its earliest stage? Is it true? Yes, dogs can smell cancer because of their excellent sense of smell.
Olfactory cortex dominates a dog’s mind in opposition to our dominant visual cortex. Dogs are guided by the scent rather than the sight of their targets, for example, dogs cannot distinguish between green and red objects but can smell the target object.
Studies show that dogs can smell the missing amino acids in their foods; and may skip meals1. Then, how can we doubt their cancer smelling abilities?
