The coating of the No-Hides, when moistened, could come off and soil light-colored carpets. You may want to limit chewing to tile or wood floors or give No-Hides to your dog when it is in its crate (which helps your dog build a very positive association with being in a crate). You can also easily teach your dog to lay on a mat or towel when it is chewing a No-Hide. The mat or towel can then easily be washed if necessary.
