The witch doctor has several "pets" that can take damage, zombie dogs and gargantuan, but what about the other spells with rune effects?
Zombie wall has a rune that has 3 zombies emerge completely from the ground that attack (I assume for the duration of the spell which is 5 seconds)
Corpse spiders I haven't seen attacked, but what about the Spider queen rune?
There are some others, such as the acid blob summoned from acid cloud, or the spectre from spirit barrage, but I assume that those are both immune to damage

Also Does anyone know if fetishes are attackable?
The only other "pet" you forgot to mention that I can think of is the toad of hugeness.
