I feel the need to point these mods out to people, I've seen a number of increased people spouting BS about the mod being broken due to being unable to tame certain Dragons (imho Toxic). These mods I'm about to list help with the taming of these Dragons that have bugged hunger bars that don't drop during knockout taming.

Not sure about this mod below, but it appears new items were added recently there seems to be a hunger depleter that was added but I haven't tested it. I suggest getting this mod anyways for after battle healing, you won't have to wait minutes upon minutes in order to heal the massive chunk of HP your Dragon lost during a battle with this mod.

These are other mods I've found that 'help' with taming as well. Though personally I haven't tested them.

Hope this helps you folks and prevents you from asking unneeded questions and annoying the mod dev about a issue he/she knows about already and is actively trying to resolve it.
