Behavior
On a world with pvp=false tamed Dogs attack another player when it is accidentaly hit/shot by him.
Background
It is nearly impossible to avoid accidentaly hitting/shooting dogs from time to time (especially in Pillager Raids and since swords are doing cleave-damage) when playing together with a party of four.
Expected Behavior
Since tamed Dogs are like an attachment to a player I would expect them to not be hittable/shootable by friendly players or (since that may cause other problems) at least not attack them back when hit/shot.
PvP is Player vs Player you want PvE off if you don't want wolfs to attack
