Is there a command or plug in to stop people from harming animals in Minecraft?

My friend in my server keeps killing my dog and I use coreprotect to bring him back, but is there any way to turn a specific users ability to do that? Thank you!

Solution 1:

There is no advanced permissions system in Vanilla Minecraft.

The best you can do on the player side is to give the player Weakness with a level of 4 or higher:

/effect give <name> weakness 2 3

But that way someone with a Sharpness 5 diamond axe and Strength 2 can deal 1½ hearts of damage with a critical hit. So you should probably modify the dog instead. This command makes the nearest dog or wolf invincible:

/data merge entity @e[type=wolf,sort=nearest,limit=1] {Invulnerable:1}
