Can someone elaborate on this for me? I don't get it.
The dogs come out at certain HP thresholds (I think it's every 10-15% roughly). Unlike all other bosses that have a shift in behavior when certain HP thresholds are breeched (i.e. 85%/55% on Titan/Twintania, 55% on Garuda, 70% on Cadecus, etc.) there's no transition period to signify that something's occurring. However, it isn't a "reverse DPS check" but just a fight where you can't ignore the adds like you can on Tyrant later on.
In fact the entire instance is just one massive "learn that dealing with adds can be different in how it's done". You need to kill the dogs quickly, pace yourself on Zu's eggs/hatchlings, can completely ignore Tyrant's adds, and prioritize the crawling zombies on Siren.
