I don't believe in self awareness, it's either you know the reflection of your image process, or in the case of the monkey, you'll figure out that the movements in the mirror are the same in the non virtual world, I also don't believe that monkeys and humans are the only beings that knowledge and identify them self in the mirror, don't forget that mirrors and very frequently present in nature (water, ice, shadows...) I support the idea of testing it on your dog, if he gets familiar with the mirror, I'm sure he'll identify itself in it.
