When my pup was that young I would pick up water 2 hours before bedtime and would give water back at 7am. Feedings were at 7am, 12:30, and 5:30 I gave him 15-20 minutes whatever he didn't eat I would pick up. I wouldn't scold when accidents occurred they're you're fault for not taking the pup out enough
if she has an accident take a step back in duration. For example you take the pup out every two hours for a few days -no accidents awesome! Push it to three hours oops! Pup had an accident you went too fast you're fault. Step it back to two hours for a few days. As for the chewing just keep up with redirecting to appropriate items to chew. She chews on your shoes your fault for leaving them out
take the shoe from her give her one of her toys get her engaged in her toy and praise praise! She will get it eventually she's still a baby and has only been here on this earth for 13 weeks (3 weeks in your home) she will learn the rules as long as you stay consistent good luck!
