Mike, a radio host and musician from the USA, wanted to see what his dog Aaron was doing while he was gone. He bought a Go Pro and attached it on Aaron. What he saw both surprised Mike and broke his heart.
Aaron waited for Mike to come back for a while. He then looked through the window, waited at the door again, looked for somebody at home, and when he couldn't find anybody, he went on his owner's bed and started howling and crying with despair. Mike, who has had the dog for 6 years, was very surprised after watching the footage, because he had never seen him howling before.
