This is a picture of Riley... and it has not been doctored.
Riley is a bichon frise/poodle mix who seems to grin with both his mouth and his eyes. According to his owner, Maureen Ravelo, of San Jose CA, Riley has such humanlike facial expressions, she frequently forgets he is a dog. In addition to his grin, Riley also flashes a snobbish and a curious look.
Ms. Ravelo said, "The most unique part about him is he thinks he’s human like us,... He loves to sit up on chairs while we’re eating dinner and sleeps with us in bed... Sometimes, I wonder if he realizes he’s really a dog..."
Cute as he is, I think that having a dog look at me like that would creep me out.
