You should consider that a puppy has an absolute right to chew whatever they can get at in your absence. You must put the puppy where either it cannot do any damage, or you do not care about the possible damage. Puppies can eat kitchen cabinets, destroy furniture, chew on carpet and damage a wide variety of other things. Besides the destruction, the puppy may well injure itself, even seriously. Please put your pup in an environment it can't destroy.
Puppies are too immature to handle temptations.
Depending on the breed, most dogs begin to gain the maturity to handle short stints with mild temptations when they're about 6 months old. Consider the analogy with a baby, where you keep it in a crib, stroller, or pen if you are not holding it. It is essential to puppy-proof your home. You should think of it in the same way as child-proofing your house but be more thorough about it. Puppies are smaller and more active than babies and have sharp teeth and claws.
