A puppy pen should be in every house where there is a dog, because all pets need a place of their own, a place where no one else can enter. Dogs do not like it when there is much noise and agitation; this can happen quite often in families with children or that have guests very often. Under such circumstances, it is wise to create a special place for your dog, where he feels protected and safe. It is your responsibility to keep your pet safe, to make sure he is comfortable and he has a suitable place to retreat when things are too much for him.
