The latest series of dog photographer Christian Vieler features pairs basset hounds, border collies and labradors trying to catch a treat in mid-air. The amazing photographs capture a humorous range of expressions, from expectancy to surprise, disbelief to joy. Vieler, who hails from Germany, has been taking dog portraits since 2016, and is grateful to have the chance to work with these wonderful creatures. More of his work here and on Instagram.
