I would say definitely not a purebred. I know from experience that pounds arent a;ways even close. Here's why::: When we got Jake from the pound, they told us he was a neutered pit bull, shepard mix. Two weeks late, Jake escaped and ended up back at the pound. When I picked him up, they said he was unneutered shepard lab mix. I had to argue with them that he was mine. They kept saying "Well, are you sure he's fixed?" I explained that they are the ones that told me that. After extensive research, I've decided he is most likely a Rodesian Ridgeback/Harrier mix (and neutered LOL). Your best bet is just to research yourself. And, unless you are planning on breeding, papers and such shouldn't an issue. Good luck.
