Nala is chewing things that she shouldn't, not anything that would hurt her, things like shoes and other human type items. We can't catch her at it to disipline her then, and am not sure sure if disiplining her "after the fact" is gonna work for any number of reasons. She is crated when we are gone from the house. This mostly happens at night when we are asleep as the dogs do have the run of the house. We need some ideas and suggestions please. Thank-you.
