Carrie is a woman that Quagmire falls in love with in "Must Love Dogs".
During trick-or-treat night, Quagmire meets Carrie escorting her niece around and hits it off, but during a date out for coffee, he discovers that she's a dog lover and he finds himself trying to pose as one as well. After briefly considering buying one, he approaches Brian about posing as his dog, and, after Brian enjoys a good laugh at his expense, agrees to it. As Quagmire worries about Brian acting like a real dog, the latter admits he's really just waiting to see Quagmire crash and burn. He decides to help things along when Quagmire insists that she's the one by presenting an engagement ring to her, and she accepts. After the initial shock, Quagmire seems to accept the news well until she moves in with all of her rescue dogs. During their engagement dinner party, Quagmire accidentally uses the word 'walk' and causes a stampede. With the party ruined, Quagmire finally reaches his wits end and admits he lied and actually hates dogs, breaking up the relationship over his lie.
Carrie is voiced by Rachael MacFarlane.
