Wolf Infection
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Mod Description
Wolf Infection turns Minecraft’s loyal canines into a rapidly spreading, pack-building menace. With this mod, wolves will hunt and attack every mob they see — passive, neutral, or hostile.
And the twist? Any mob killed by a wolf is reborn as another wolf. The infection spreads. The pack grows. Nature fights back.
Features:
- Wolves now attack all mobs
- When a mob dies to a wolf they become another wolf
