A Heartwarming Photo Series That Captures a Dog’s Goofy Grinned Excitement for an Incoming Treat

German photographer Christian Vieler created a really wonderfully heartwarming photo series that captures the pure excitement and goofy grins on the faces of different dogs as they reached out their hopeful heads for an incoming treat. A collection of these photos are being released as a book, aptly entitled Treat, in April 2017.

Treat is an irresistible collection of sixty charming dogs captured at one of their favorite moments–snack time. Photographer Christian Vieler caught these eager dogs anticipating, catching–some more successfully than others–and enjoying a scrumptious tidbit.
