We have been led to believe that dogs are colorblind but they have a wonderful sense of smell. I pretty much agree with this but I'm wondering if they don't have an enhanced level of smell that we humans have no clue of. Sort of like a color degree of smell that we humans have never experienced. I read yesterday that the dog's sense of smell is 100,000 times more than a humans. I find this hard to believe. A hundred times better maybe but I have my doubts. A thousand times makes me question the person, or persons making these claims. How could they know? Do they count nerve endings in our noses? 

I make the claim that instead of 100,000 times the sensitivity there is a aspect of odors that we so called advanced apes can not comprehend. Imagine smelling someones butt as the dogs do and getting a 100,000 times the jolt. I think that would be more than simple sensory overload. It would knock us into next year. 

I make no claims of being a zoologist but I do posses a pretty strong common sense. Just sayin'. Maybe stuff like this doesn't keep you awake at night. Actually nothing keeps me awake at night but I know there are gangs of  worrywarts out there to take up the slack. So keep calm and carry on.
