If you have a dog, expect him to chew. Provide him with his own toys and teach him to use them or he will chew anything available, such as your furniture and clothing. Dogs do not chew your house and belongings because they are angry, jealous or spiteful. They do it because they are dogs. They may be lonely, bored, frustrated or anxious, but they are not malicious, vindictive or petty.
Active dogs can become restless when left alone for long periods.
If you always come home at a certain time and you are late, your dog may become anxious. Your dog does not punish you for being late by chewing. The dog chews as a form of occupational therapy to relieve stress and release energy. If you come home and find that your dog has destroyed something, do not punish the dog. Passive Training Until your dog can be trusted not to destroy your home and yard, do not give him free, unsupervised run of your house.
