Little is known about Dexie other than the fact she is owned by McIntosh.
Events of GTA V
During the events of Grand Theft Auto V, Trevor Philips, is ordered by Nigel and Mrs. Thornhill to collect Dexie's collar as a souvenir, which results her fleeing at the sight of Trevor when approached, much to the dismay of McIntosh. After following Dexie to a stop, he approaches Dexie and takes her jewel-encrusted collar. Dexie then flees from Trevor, presumably returning to her owner.
- Although the player is able to aim at Dexie in the mission Vinewood Souvenirs - Kerry, shooting Dexie will fail the mission.
- Dexie's name might be a reference to the drug Dexedrine, a popular brand of dextroamphetamine.
- Dexie, along with Puddles, Hugo, Chop and Valentino, are the only named dogs in the entire GTA series.
