Do animals have free Will?

They can smell you for starters. Dogs rely heavily on scent in many aspects. They know where you are from scent rather than sight immediately.

In what way do you mean you figure they are looking at themselves? In what way does their behaviour change from being aware the image has no scent.

The mirror test is a bit shaky to be honest, but I'd be interested to know.

I would agree with the scent if it took place outside and a breeze was blowing toward them from me, could be a thing to try. However in my home my scent is prevalent everywhere so they do not use that scenting aspect in the house, that is unless the wife is cooking.
After they have seen themselves the first time and try to scent for a different dog, they will stand and look at themselves every time after that until they get board, which really doesn't take a rottie long.
