Minecraft wiki entry for Creeper, associated text: Creepers are not targeted by tamed wolves, iron golems or zoglins. However, they are still attacked by withers, snow golems, vindicators named "Johnny", and goats. For snow golems, this was reported as a bug and is listed as either "unresolved"[2] or "works as intended"[3]. When hit by a stray projectile (like a drowned's trident), a creeper retaliates if not already chasing a player, unless said projectile is a skeleton's arrow. When attacked by a goat, or poisoned by a pufferfish, a creeper does not retaliate.
