RevampedWolf

RevampedWolf mod fundamentally improves standard wolves in Minecraft, adding more depth and functionality to them. These mobs have become much more interesting thanks to enhanced artificial intelligence, the ability to wear armor, and other innovations.
Main Features
Wolves spawning in the wild now form packs with a leader. The entire group follows the leader and acts in coordination.
Wild wolves attack animals only when hungry, making their behavior more realistic. When they find meat, hungry wolves head towards it to satisfy their hunger.
A wolf armor system has been added to protect your pets in combat. A saturation-based healing system has also been implemented - wolves restore health by consuming accumulated saturation, similar to players.
Saturation-based Healing System
When you feed a wolf meat, its saturation level increases. If the wolf takes damage and has stored saturation, it automatically recovers health by consuming this resource.
