Filled with impossible situations and hilarious gags, this comic allegory follows the adventures of Wilby Daniels (Tommy Kirk) after he finds an ancient mysterious ring and unintentionally casts a hex on himself and turns into a huge sheepdog. The only other odd thing is that Wilby still has his voice intact. Back and forth he goes, constantly changing from the pooch to his human self. While this amuses his brother, it positively amazes his neighbors, the local police, and a brunette beauty on his street. As if his bad hair days weren't enough, Wilby soon learns that a group of spies has moved into the neighborhood. This initially bad news might turn into his chance to perform a final heroic act that could free him from the spell altogether.
