No matter how much his owners would try to console him, there is no helping this guy. Simply said, seeing your ex in public like that makes recovery difficult. See this man's face; he is completely horrified. He finds what he is seeing hardly believable. His brain is still processing what he is seeing before him while his heart has dropped all the way to his jeans.
The intense emotion seen in this picture tells volumes about universal events spanning species lines. The dog's face captures exactly that moment of panic and incredulity that accompany unexpected meetings: the wide eyes, the slightly agape mouth, and that unmistakable look of "I can't believe this is happening right now." It's funny how canine expressions might so precisely reflect human emotions, particularly in social awkwardness. Anyone who has ever had an awkward public interaction will relate to the dog's seeming search for solace from its owners looking extremely ashamed at the same time. The dog's size adds even more humour to the expression; seeing such a big, presumably dignified animal appearing so completely discombobulated makes one laugh especially. This picture shows that even our four-legged pals experience those embarrassing social situations that cause us to wish to hide behind the closest fire hydrant.
