Woof was a member of the Jokerz.
Woof was a giggling criminal that was spliced with DNA from a hyena, and joined the gang of Jokerz lead by the resurrected Joker. He would often be paired with Ghoul, during various robberies committed at the request of their leader.
When the Jokerz broke into Gotham Shipping to steal one of the components for a satellite jammer system, Woof dispatched of the guard with two attacks, to which Ghoul stated that the guard "should have said 'heel.'" Shortly therefore, they were caught by Batman. Although Batman managed to fight on even ground against them, Woof managed to scratch him a few times as well as bite him on the shoulder, to which the latter injury caused Batman, AKA Terry McGinnis, to have a bad time during his date due to exhaustion.
In an alternate future, Woof and his old gang worked for Chronos. Woof had been physically altered to have robotic arms with metallic claws. Under Chronos's orders, the Jokerz attacked time displaced Justice League members Batman, Green Lantern and Wonder Woman, but they were interrupted by the JLU. During the Jokerz's final battle against the Justice League and JLU, Woof was able to pin down Warhawk. When he was about to deal the killing blow, Warhawk's father, John Stewart, blasted him with his ring.
Woof only has one speaking line in the entire DCAU (when he and the other Jokerz all say "Sorry, Lord Chronos" at once), along with a few growls. In Paul Dini's published screenplay for Return of the Joker, Woof has one line in the movie, a brief curse when the Jokerz are caught by the GPD while fleeing the Jolly Jack Candy Factory.
According to the DVD commentary for Return of the Joker, Woof's appearance as a spliced hyena was a deliberate nod to Bud and Lou, the "pet" hyenas kept by the Joker and Harley Quinn in Batman: The Animated Series.
