zPetProtect is a simple, straightforward response to this plugin request. It makes tamed wolves immune from any player damage coming from a player other than their owner.
Specifically, it blocks damage from the following sources:
Projectiles
Fire (in case they attempt to grief past this protection by putting a fire down)
Fire ticks (same as above)
Block explosions (placing TNT, again, to try and grief your puppy)
Entity Attacks of all types coming from players (not other entities)
To-Do
Cats & other tamable creatures options
"PvP" support that makes the pet wolves damageable if that wolf has damaged you (so wolves aren't invincible in PvP).
