The Pack Leader is a wolf that appears in The Sims 2: Pets. He has dark fur and glowing yellow eyes. He comes onto residential lots like any other stray, but only at night (unless cheats are used). Like other strays, he will not appear in college sub-neighborhoods. Pack Leaders have various names.
If a high enough relationship is built between a Sim and the wolf, the wolf will 'nibble' the Sim and the Sim will become a werewolf. Unlike other stray pets, the pack leader can only be adopted with the use of cheats. but will turn into a regular wolf.
Trivia
The use of the term 'Pack Leader' or 'Leader of the Pack' in game as opposed to 'Alpha', may be a reference to the 1964 song, 'Leader of the Pack' by the Shangri-Las.
