Animals we respect the intelligence of - our pet dogs and cats, perhaps
monkeys used in experiments in laboratories, seem not to have the simple(to our minds) capability of understanding the function of a mirror, and know its themselves, or even an animal of a similar kind that's being reflected.
Similarly, at least the dogs I've had experience with, have always been
unresponsive to dogs barking or in pictures on TV. I have seen and heard of some exceptions.
I'd like to see a photo of your dog or cat, etc. that seems to understand a reflection or an image being related to him or her, on TV or in a mirror etc. I'm sure there are some examples. Do you think this understanding can be instilled by the pets owner though any training process ?
