What could my dog be mixed with?

I got a puppy from the pound I've had him for about 4weeks he is Now about 5-6 months and weighs 31 pounds . I think he is part plott hound because he he has plot hound stripes on his head and legs and has floppy ears like all hounds do. His tail kinda curves up and he has a white spot on his chest and a little around his toes. His hair on his back is black, short and fine. I know there are many things he could be mixed with but if anyone has any guesses then let me know. I will put a pic of him if i figure out how to do it
