Why does my dog sleep in and eat her poop?

My dog is a 6-7 month old lab/pit/shepherded mix (as per the shelter). She was extremely sick when I got her (she was treated for parvo but did not have it and got better). I taker her out every hour for a walk so she can go poddy, additionally if she is gassy or wipers at the door I take her out. She has several behavioral issues such as, eating everything, peeing/pooping off pee pads, eating her filled and empty pee pads, biting me, getting extremely rough while playing, and going crazy on the leash while walking. I have been working with her to stop the negative behaviors (they started all the sudden without warring). I have tried kenneling her at night and when I leave for work, giving her a routine,and locking her in the bathroom for punishment. I should also note I play with her until she goes into her crazy semi-aggressive mode and starts to biting/jumping on me hard (often hurting me and making me bleed). I am not sure what else to do. But not with her eating and sleeping in her own poop (this started today) I am at then end of what I can handle. Since I rent an apartment I cannot afford for her to completely destroy my place. I have also used every carpet cleaner to take the smell out, At the time of cleaning I will not smell a thing but it always come back. I love her with all my hart and want it to all work out.
