Some new features and bugfixes were added by vkey ( https://github.com/vkey) and Igzak (Yurii) ( https://github.com/Igzak) on GitHub, those are listed below:

• Dogs sometimes lose stats on worldchange
• Owners can now no longer accidentally hurt their dogs
• Arrows can't hurt dogs (I've later made that configurable)
• Dogs can be revived, at a cost (I've later remade it and made it toggleable and the price per level can be adjusted)
• Only the dog owner can rename dogs
• [New Mode] Dogs can be in Attack or Defend mode (crouch right-click). On Attack mode, they will actively hunt mobs around a player.
• An error would appear when a dog got killed when the owner was not online

I've also fixed a bug where a dog's damage stat would not get applied right after taming, and updated the Spigot API to 1.19.2 (though I have yet to introduce the new mobs).
