Scientists have made a signifcant breakthrough in understanding how dogs can detect low blood sugar levels in diabetic people. The insight could lead to many new medical innovations relating to illness detection and sensory based signalling.
We all know how reliant dogs are on their noses over and above their eyes and this latest research has revealed how dogs see the world through their nose. Our canine pals can detect the very smallest smells when concentrations are as incredible as one part per trillion. This would be like asking a human if they could smell a teaspoon of sweetener in an area of water the same as two swimming pools.
See how they do it. Dogs, will they ever stop amazing us with their talent for making human life better!
