If you catch him with a pair of shoes that he was already able to ruin, just get rid of the shoes and move on. Make sure that you do not punish him or reprimand him, as this might be damaging for him, rather than correct his behavior, although you might think that you were able to let your dog understand that he did something bad. If you see him after he has destroyed something, you could say “What did you do?” using a firm tone. Your tone should be firm enough to let him know that he did a bad thing.

Remember that young puppies teethe at around 3 to 6 months of age and chewing would be the only thing they could do to satisfy them or to alleviate the pain. Eventually, as they get all their teeth, they will have a less urge to chew on stuff. Also make sure that you play with your dog a lot. The more time you give to interact with him, the more loved and important he will feel, thus making him less bored and less interested in chewing on stuff. Patience and love for your dog is the key.
