Basically the tittle.

Currently, mobs crafted by the player like the Iron Golem and tamed like the wolf are passive towards the player, but can become become hostile to each other if attacked. This can results in troubles if you accidentally hit your own Iron Golem by accident, causing tamed wolves to attack and Iron Golems to retaliate.

So, Tamed Wolves shouldn’t attack player’s pets or crafted golems even if the player hits them, nor should crafted Iron Golems, foxes or tamed wolves ever attack an Snow Golem even if struck by accident.
