First I apologize for the writing, I used a translator
Second, I thought about these points to make the game more realistic in terms of pvp
Trained dog, broke a tile built from another player's house, death
Zombies do not enter through structures broken by another player while the player is away (dog defends with absent owner)
NPC for dog and food trade, obtained by exchanging food or weapon/tool ("x" amount of hunger or durability)
Dog whistle, stays on owner's key ring, if used within 1 min after opening the door with the "house key", the dog does not kill
Don't kill anyone in movement/action (accuracy 0), unless pvp is enabled
Activated Pvp gives 50% more damage and health
