Everyone always says they had trouble with the Defiled Watchdog. The worst, cheapest, most difficult fight, people say. Nothing is as hard as the Defiled Watchdog.
I don't get it. The only thing I can think of is that people rush into that dungeon supremely underleveled. This seems to be the case with a lot of chalice bosses, but particularly this one, because of how the damage works.
Good on you, and others, for beating a boss like that at what I can only assume is a really low level. It still took three hits to kill me by the time I was down there, and it's probably the slowest and most telegraphed boss in the game. You always know exactly what it's going to do. I had fought other Watchdogs twice already and the Defiled one was no problem for me.
However, Ludwig stonewalled me for days and I cried myself to sleep. Then I messed up my campaign and have to do it all over again. I wish I was never born.
