Ill grant you, BCIs are kinda sissy but an AfRock is quite gutsy.
“Disengaging” is the issue.
Recurved teeth prevent them from “immediately letting go” even if they desperately want to.
I would ~hope~ it would cause them to cease constricting fast enough to save the pet but I really don’t know.
Thankfully, I’ve never had to face this situation and in spite of having an insanely secure yard, my dogs are not allowed out unless I am there to watch over them.
Stuff happens and if my dogs came back inside in lame, sick or whatever, I’d want to know precisely *why* they did so to easier facilitate vet effective treatment.
I live in a Copperhead/Rattler area but they stay up on the ridges.
Hopefully, they always will.
