Dogs use their mouths a lot like humans use their hands. Their sense of touch is experienced through their mouths; they love to chew on toys, treats, clothing, shoes, furniture, sticks, bones, etc.
Some chewing is natural, such as when puppies are teething or dogs are playing “fetch.”
Some chewing is destructive. And some is darn dangerous and can lead to broken teeth, lacerations, foreign bodies, electrical shock, etc.
