Stress and anxiety caused by stressful living conditions or to much scolding or punishment.

Teething just like teething babies puppies need to chew to cut their teeth just giving your puppy a chew toy that he can chew will solve this usually.

Puppy proof your home move all expensive items out of puppies reach. Move all electric cables and other dangerous items away from puppy.

Provide him with plenty of chew toys so that he does not have to chew your personal items, praise him when he chews the toys, some toys hold treats inside this makes it a game for the puppy finding how to get the treat out.
