Episode Title:
Shades of Gray.
Episode Description:
Danny has difficulty with a ghost dog, and every time it appears, it causes trouble. Within the Axion building, the ghost dog goes out of control, and both Danny Phantom and the building's security system (designed by Valerie Gray's father) prove unable to stop the ghost dog from destroying the lab. As Valerie's life turns upside down because of Danny Phantom, a "generous benefactor" (revealed to be Vlad Masters/Vlad Plasmius himself) helps Valerie exact revenge on Danny Phantom by turning her into a professional ghost hunter.
