Interesting Discoveries

Pets usually recognize their owner by their voice, features, smell, etc. In the National Geographic article by Liz Langley, she discovered that dogs are not able to recognize their owners while looking at a phone or table screen. Do you think its because they are not able to sense their owner's presence? It makes me think if dogs understand what is really going on while looking at their owners through a phone screen. I think this new discovery is very interesting. What do you think?
