Actually even when Brannagh fully connected she never tried to do damage. The damage was from us silly humans pulling back suddenly and dragging her teeth. She tried to bite a lot granted...she actually connected very rarely and never left any real damage. I've said it before...I've been bit worse by my own kids LOL. Much of the work with Brann the Brat was just trying not to drop her as she torqued her body around in our grip. Hard to find that right grip...enough to hold her firm without feeling we were harming her. It got easier each time and she just finally got it through her snake brain that we weren't turning her loose till she calmed down.
Just stick with your little bp. Some don't like much handling but at least if he'll accept enough to allow for stress free husbandry then that's a nice step (or slither) forward. That's all we ever really expected from Brannagh, yet once she stopped actively trying to bite us...she just didn't have an attitude about much anything else anymore. She still retains her aggressive feed response but that's a good thing!
