serrated maw doesn’t stack like on other mobs since the dog is so busy bouncing off and running around - dog should stay pounced on monsters and it should continue to stack - it would making remote detonation work better.
serrated maw augment should continue stacking on pounced mobs as well, it currently falls off of pinned mobs shortly after - seems antithetical to the purpose. Interestingly enough voltiac mandible seems to continue to be applied despite the tool tip only saying 5 seconds.
