Lost dog, Chandelle Court, 9S075, Naperville — shy male with a white wavy coat and tan markings

Charlie has a collar that says "Huck." We just adopted him a week ago. He is extremely shy and will run away if you approach him. He has a medium length wavy white coat with tan ears and tan patches on the side of his body. He has a multicolored collar on. He has returned to the house at night but is not going into his crate that we have set outside.
