How to get my dog to stop chewing things.?

He is about 1 yr. He chews rugs, phone chargers, wooden gates, leather couches, shoes, and doors. He lives in chew toy heaven. My family and I have had him since early feburary. He's a really sweet dog, got him from the shelter. Not really sure what happened before that. The people at the shelter suggest he couldn't be kept. We have two other dogs. Fritz (the chewer) and Mimi and both daushaunds. Our other dog JJ is a lasopso. He also digs a lot but I heard that's a daushchand thing. We just got him potty trained and are trying to get him to remember the commands we taught him when we got him. Is there anything I can do to make him stop chewing things?
