A photographer has created a series of paw-traits of hungry dogs pulling hilarious faces as they try and catch treats. Using a unique technique, the shots are captured at the exact moment the adorable pooches attempt to catch an airborne piece of food. The dogs appear surprised, happy, sad, confused – and sometimes even so blasé they miss the treat entirely. The images were taken by Christian Vieler, a photographer from Waltrop, Germany. Here: A labrador retriever. (Photo by Christian Vieler/Caters News)
