What a sh*tty annoying boss. Here is how to defeat it if you play Glass Cannon, in which case it is horribly annoying boss, who will give you no time to do anything. When approaching the arena, right when gladiator starts to standing up, blast him with Crystal Soul Spear, twice, if you can. Wolves (fckng annoying btchs) will start approaching, swap to Soul Greatsword, it has great range and arc, so it will be fairly easy to slay the wolves (if anything, just run away, dodge, and catch the moment with the SG). Then, start slaying the gladiator, with SG it is most optimal. When this crying little cnt will call his turbo dog, you'll have some time to attack him, then, when doggo starts turbo jumping, dodge, and, catch it with Toxic Mist Pyromancy. When dog's health go to the point of stage 2, red eyes and super-turbo engine in the arse, upon swapping the stage it will cast AOE frostbite, standing motionless. Use this time to slay it with 2 Crystal Soul Spears. Dude, this turbo jumping sht is so unbalanced and annoying, it can jump through the pillars behind your back. And you better slay it right away in the start of the stage 2, because turbo jumping becomes also AOE frostbite attack.
