[Breed] Does anyone have experience with pointer/pitbull terrier mix?

I am adopting a dog for the first time, and there is a 3 year old male pointer/pit mix that I'm interested in rescuing. Does anyone have any experience with what this mixed breed is like? Personality, temperament, energy level, and train-ability, etc.. via /r/dogs http://ift.tt/2qUge4f
