Destructive behaviour is very common in young dogs. Puppies need to chew, especially during teething, as this soothes their aching or itching gums. It is also a way of exploring their world. Older dogs may also be destructive.
Puppies can be very destructive if not managed properly. If your puppy starts to chew furniture or doors, tell it 'no' firmly and give it one of its own toys to chew. Whenever you see it chewing its own toy, praise it. If the puppy persists, try using water pistol. Squirt the puppy in the face when it starts to chew. Do not say anything. It is best that the puppy associate the unpleasant event with the object it is chewing and not with you. Another option is to apply a deterrent such as bitter lime to objects that may be chewed.

• Train your new puppy to chew its own toys.
• Do not leave puppies or newly acquired older dogs alone with access to valuable furniture. Leave them in a laundry area with plenty of toys or maybe a bone to chew.
