The only thing of any concern really is the Vengeful spirits, you need to keep your pet away from them, or typically they'll just get mend pet aggro'd to you and then it doesn't matter. They will kill your pet, though, if he has threat on them and you don't pull him away.
The Isle of Giants devilsaurs however, hit far, far harder than warbringers. I haven't found a viable way to pet tank them. They can however, be kited. There's also a screwy way to kill them involving the cave where the bone collector is and distracting shot glyph to ping-pong them between your pet in the cave and you above the cave. There are probably youtube videos on it. I've solo'd a good number of them as well using that tactic.
