On February 7, 1984, Dynamite Kid captured the WWF Junior Heavyweight Championship by winning a tournament. He defeated Davey Boy Smith earlier in the tournament, and would go on to defeat The Cobra in the finals.
Dynamite Kid made his WWF television debut on 29 August 1984, where he and Bret Hart defeated Iron Mike Sharpe and Troy Alexander in a match eventually shown on 15 September 1984. Kid would end up teaming with Davey Boy Smith as the British Bulldogs, while Bret would turn heel and team with Jim Neidhart as The Hart Foundation, and it led to matches between the two teams that usually ended in no contests. On 7 April 1986, accompanied by Captain Lou Albano and Ozzy Osbourne, the British Bulldogs won the WWF World Tag Team Titles from Greg Valentine and Brutus Beefcake at WrestleMania II.
Dynamite Kid would suffer a serious injury in a tag team match that took place in December 1986 in Hamilton, Ontario, Canada against Don Muraco and Bob Orton, Jr., and several wrestlers including Roddy Piper, Junkyard Dog and Billy Jack Haynes would substitute for him when tag title defenses were made.
The British Bulldogs lost the titles to the Hart Foundation on the February 7, 1987 edition of WWF Superstars of Wrestling. The match itself was an odd sight, as Dynamite could barely walk due to back surgery. Dynamite was knocked out by Jimmy Hart's megaphone early in the match, avoiding him having to wrestle much in the match for story purposes. From that point forward, the Bulldogs would not be a top-tier team anymore, and while they would not become straight jobbers, they would mostly wrestle to double disqualifications, double countouts or time-limit draws against the top teams in the WWF.
The Bulldogs wrestled their last WWF match at the 1988 Survivor Series. Although their team would win the match after team captains The Powers of Pain (The Barbarian and The Warlord) eliminated the last remaining opponents The Conquistadores, the Bulldogs had earlier been eliminated when Dynamite had been pinned by Smash of Demolition.
On December 5, 2018, Dynamite Kid passed away.
