Help Identify My Rescue?

My rescue looks like part Catahoula and ? She is hyper, runs like the wind. She has a 36 inch vertical jump, chews, and digs. She loves children, but seems to be somewhat protective. Delta weighs 38 lbs and is almost a year old. She is definitely an alpha, but sweet. Any guesses what might be part of her mix? Thanks.
