Angry Dog

The Angry Dog is a rare Pre-Hardmode enemy that spawns in the Snow biome. It charges and rams into the player at high speeds, although it is slow at turning around. When damaged to health, it will curl up into a ball and roll towards the player with increased maneuverability. It also inflicts the Bleeding debuff on contact. It gets significantly stronger after Cryogen has been defeated, with boosts to its damage, maximum life, and defense.
