Star athlete Jack Wheeler went to college on a football scholarship. After an injury forced him off the team, he dropped out, unable to afford tuition. He opted instead for a tour of duty with the U.S. Marines, which ended in tragedy when most of his comrades were killed by a terrorist bomb. Disheartened, Wheeler left the Marines and returned to Quad Cities, Iowa, taking night classes at State University. He also fell in love with Claire Smith -- only to see her struck down by a gunman. The police investigation revealed that her last name was really Carmonti and that she was the daughter of a recently killed Chicago mob boss. She was not a random victim, but a target. Something inside Wheeler snapped. Donning a hockey-mask, khakis, and a State U. T-Shirt, he became the crime fighter "Wild Dog". He was soon a local hero, even though wanted by the police for his ruthless vigilantism. Wheeler spent his days as an auto-mechanic, and his nights as a protector of the innocent.
Wild Dog was present at the great summit during Invasion! when the heroes of the world gathered underneath the leadership of Captain Atom to strike back at the Alien Alliance. The time that Lobo came to New York City and fought against DC Comics editor Mike Carlin, Wild Dog was part of a team of seldom-used heroes and villains sent after him. This random selection also included Black Condor, El Diablo, Garryn Bek, Human Flea, Strata, Velvet Tiger and Wotan. He also took part in the Battle of Metropolis during Infinite Crisis where he teamed up with Crimson Avenger and Vigilante to take down Madmen and the Trigger Twins. They gunned them down from the rooftops.
Booster Gold created an alternate timeline when he went back in history to save his friend Blue Beetle from being murdered by Maxwell Lord. In this world, Lord had taken over the planet using a mentally controlled Superman and his personal army of OMACs. There was a small resistance force of heroes still fighting to stay alive, led by Green Arrow and Hawkman including Anthro and Pantha, along with Wild Dog. They made their final assault on Checkmate Headquarters, but during the fighting Lord used his mind control abilities to force Wild Dog to shoot Pantha and then himself in the face. Beetle eventually sacrificed himself to repair the timestream.
