Bernie Gumsher is a lazy sheepdog who was briefly a part of the Scooby-Doo Detective Agency.
Bernie is a heavy-set brown dog with a black nose and a blue collar.
Though a coward like Scooby-Doo before him, Bernie is far more lazy and unmotivated.
While the gang was attempting to recapture Time Slime, Scooby-Doo was sucked into a temporal vortex and was so traumatized by the experience that he quit the ghost-hunting business. Despite the pleas of his friends, Scooby adamantly refused to return.
Putting the hunt for Time Slime on hold, the gang, after interviewing several anthropomorphic dogs to replace him, hired Bernie at Flim-Flam's insistence. Bernie quickly proved to be the worst possible candidate, and the gang was easily subdued by Time Slime.
Realizing the dire situation, Vincent Van Ghoul took Scooby into the future, showing him the horrible future that would come about if Scooby did not return to stop Time Slime. Horrified at the sight, Scooby decided to return and defeated Time Slime. The gang welcomed Scooby back with open arms, and Bernie was dismissed.
