I saw this at the Plymouth Independent Film Festival, and I laughed and (almost) cried. A little dog barks at everything, and this animation short depicts why he barks at it. A little dark in some places, but hilarious in others. For example, he saw a girl with a jump rope while he and his owner were walking in the park, and he barked at her because he thought that that girl would give the jump rope to his owner, and the jump rope would start spinning and cuts his head off. This went on for many other innocent creatures (grasshopper, squirrel, butterfly, flower, etc.), and the dog began to bark around at everything in order to protect his master. At the end, his leash got tangled around the master and he killed him. I loved this. See it!
