Puppies only love chewing your furniture, shoes, books, newspapers and homework so much because they can't find anything tastier to chew upon, and chewing is their natural urge especially to relieve teething pain.
Looking into their eyes you can tell there is no malice in their actions and healthy natural puppy treats and chews are ideal for them.
It is advisable to supervise dogs, and puppies especially, eating chewing snacks in case of choking.
