The exercise ball needs to be put somewhere inaccessible to the dog. Plenty of walks/exercise and toys he can chew relieve boredom and the urge to chew things he should not chew. We trained our dog to stay off the furniture by putting a piece of cardboard in front of the chair across the opening, some folks use aluminum foil most dogs don't like either. Hitting the dog or kicking him is never a good idea, it will produce a dog that cowers and fears you and most likely will not correct the undesired behavior. These days you may get a visit from the ASPCA if you're observed hitting/kicking your dog.
