missing quail

I woke up to a missing quail. came home from the city i unleashed jack dog turned around saw a brown ball in his mouth. guess what it was a quail. his body was badly tattered but he was still alive. his wounds looked superficial. I don't think jack did all the damage it was too short a time frame. he is missing feathers galore. I didn't see any puncture wounds. may have been Jill cat who did the damage and jack rescued the quail? put back the quail in the cage. hope he lives.
