Some dogs deliberately seek attention with negative behaviors. You need to reinforce your dog for the good behaviors and ignore it for the bad ones. Also, remove all inappropriate objects and give your pet only its chewing toys. Disallow your dog to play with items that don't belong to it. Exercise your pet regularly so that it has sufficient play time.
Dogs investigate objects with their mouths.
If left unsupervised, they will certainly damage things. Don't punish your dog excessively for a chewing incident as this will increase its stress levels and cause it to chew destructively in your absence. Adult dogs may suffer from gum problems which they try to relieve by chewing. Have your vet check for dental problems. If your dog is hungry because it has no regular feeding times, it may also chew and destroy household objects.
