While the human brain is dominated by a large visual cortex, the dog brain is dominated by an olfactory cortex. The olfactory bulb in dogs is roughly forty times bigger than the olfactory bulb in humans, relative to total brain size, with 125 to 220 million smell-sensitive receptors. The bloodhound exceeds this standard with nearly 300 million receptors.

Thing #04:

High Blood Sugar

Thinking of Diabetes? You’re spot on. Dogs are able to detect, using that nose, when blood sugar levels in the body of humans are becoming dangerously high. This is especially helpful for children with Diabetes who don’t always have a parent around to help monitor. These dogs can be used as service dogs to help keep their owners safe and healthy.
