Pet Owner
The Pet Owner mod is a client-side Fabric addon that significantly simplifies identifying the owners of tamed animals in Minecraft. Now you just need to look at any animal to instantly see information about its owner.

This mod works exclusively on the client side, meaning there's no need to install it on the server. All multiplayer game participants can benefit from its advantages without additional configuration.

Currently, a version for Forge is not being developed, but enthusiasts can create their own port.
