Control what he eats
You are the one to blame if your dog gnaws on your shoes. Provide your dog with chew toys and keep all valuables out of reach.
Over time he’ll get used to only chewing on toys and not your belongings.
Use voice commands to teach
If you find him chewing on something you left within his reach, you can use voice commands such as “No” and “Stop”, and then remove it from his mouth. Then give him his chewing toy.
After a few experiences, he will understand that he is able to chew on one thing but not the other.
The conclusion of the article is:
Spend time with your pet. Exercise him by taking him for runs.
Remember that tired dogs behave better.
