Bulldog is an intense womanizer, and has casual affairs with many women - whom he usually dumps just as casually - but has somewhat of a lingering crush on Roz. Following a short affair with her, Bulldog reveals his feelings towards Roz to be genuine, but they prove to be unrequited. After his show is cancelled and he is fired by the station at the end of Season 6, he returns shortly thereafter to work in the station's archives vault.
Contrary to his overbearing "machismo", Bulldog has a fear of reptiles and once jumped on a desk in panic when a small lizard got loose in the studio. He also used a pregnant Roz and later his elderly mother as human shields to protect himself from gunmen - the first incident being an attempted hold-up at the coffee shop for which Bulldog was given, and enthusiastically accepted, undeserved praise for his role in foiling, and the second a false shout by Martin to expose this cowardice at an awards ceremony for Bulldog's 'bravery', after Frasier's more subtle attempts to have Bulldog come clean failed miserably.
Bulldog was credited as a regular cast member in several episodes from seasons four through to six, until the character was fired from KACL. His last appearance is in Season 11 episode 'Frasier Lite'. He does not appear in the series finale.
