Dogs like to chew underwear, one because puppies need to sharpen their teeth, so they like to chew things. For another, the underpants have the owner’s smell on them, and in order to show that they are close and like them, they will chew them. There is also a possibility that the dog is deficient in trace elements and has xenophilia. For dogs that need to sharpen their teeth, owners should prepare some dog chews and such. The dog will eat some non-nutritious things, such as plastic bags, paper towels, dirt, sand, etc. The owner should pay attention to replenish trace elements.
