Dogs like to explore things with their mouths. They may also chew furniture or other objects out of boredom, anxiety or loneliness.
You can take steps to make the coffee table and other household items less attractive and accessible to your dog. Apply bitter spray on the furniture and put away any shoes or objects that your dog may chew on. The doors to areas that are off-limit should be kept closed.
There is a range of interesting toys that you can give your dog to chew on. These include rubber balls, teething rings and nylon bones. However, avoid giving the dog items that are similar to those that you are trying to keep him away from, such as old shoes or old clothing.
