I like the OP's post by itself. Except for the following
[BOMBPROOF_%%]
Can we get some details here? Are you referring to the possibility of explosives being added? Or will they literally explode when scared and this tag is the % chance of them not exploding. If this is the case my fortress defense will consist of a drawbridge that drops dozens of kittens on the enemies.
[FEAR_FLAME_%%] subject will enter a panic state at the sight of fire.
Erm... Pretty sure all species are afraid of an unpredictable searing hot flame raging towards them. This is due to natural selection. Lighting strikes a tree, fire starts, all species who don't run die horribly. I hardly doubt a creature would toss a coin on 'run or die'. But Certain creatures should have a NO_FEAR_TO_FIRE tag or something.

This talk of trained animals getting scared by trained animals does not amuse me so much. I've been around horses most of my life, my family boards and raises them. They're scared by sudden movements and loud noises, they're more scared of the four legged barking ball of death charging at them rather than a dog itself. For example, my neighbor's pit bull can walk right up to the horses and sniff their legs without any panic. While my golden lab will crouch down, raise his tail and bark, scaring the horses out of their mind (which happens quite often
). So the way animals work, a horse wouldn't be scared of a dog unless the dog was fighting someone else nearby. This could change with herding dogs and such*. Though I can't remember if herding dogs are planned or not.
Maybe you could make a dog scare the animals from one pasture to another during certain times of the month! Animal caretakers would do the same job, but dogs would make it go much faster. The benefits would be that you would be able to keep big grazers like yaks and water buffalos from starving to death because they eat faster than the grass grows.
That said, animals can develop a fear reaction to certain objects or other animals, if a dog does attack them. They will be scared if they see a dog. If an army of goblins whack it with a sword, they will be afraid of goblins and swords. In which case you need to acclimate it to the object/species.
