It sounds like she is acting like a puppy and the best way to approach this would be to react in the same way.
Initially, keep things she is not allowed to chew out of her way. It is important however, to give her things that she can chew. Chew toys come in all shapes and sizes so it is best to try a few to find her favorite. If you catch her chewing something she shouldn`t, say a nice firm NO! and swap what she is chewing for something she is allowed to chew.
As for the toilet training, we need to go back to basics here. Every time you put something in the front end, something is likely to come out of the back end. So every time she eats and every time she drinks, try and take her outside to potty. If she does go to the bathroom outside, give her lots of praise. Be as goofy as you can, make a really big deal of it and give her lots of fuss. If you catch her toileting in the house take her outside immediately.
Dogs learn much much quicker with positive reinforcement rather than punishment, so scalding her for doing something wrong is likely less productive than praising for things she is doing right. Also, for her to link peeing with going outside, if she is peeing in the house, she needs to be taken out immediately to associate the two things. If you wait a few minutes and then take her out, she won`t connect the two events.
