The dogs..

[Im_Sexy]

So, the dogs arent dead, they just went insane or got infected by the Turngait virus, explaining all their strange scars and glowing eyes.

This is possible because the dogs got infected to a point that they cant smell Philip when hes around? I mean, you can only be spotted if they find you with their eyes. Also they are sensible to noise, ok coming from a dog. But the fact they cant smell...yet they can smell the bief aroma... I mean, if you are hiding from a dog behind a crate or box, we will find you because they can smell you

Why is this?
I know its a games thing, has a dog finding you by the "smell" isnt very easy to do, but it can be done on other aways like the "how close you are from them/range etc"...

but my point is if theres any explanation why they can smell the bief and not you.
