    It is a Saturday morning．You have your breakfast，walk the dog，and then go to soccer practice on time．A few hours later, you return home，only to find that the dog has made your bedroom untidy．Your clothes are on the floor．．

    Before you get angry, you should stop and think．Your dog wasn't misbehaving(捣蛋)just for the fun of it．And he wasn't punishing(惩罚)for leaving． It's called separation anxiety(分离焦虑)

    Thank of it this way :Dogs ask where you're going or when you'll be back．All they know is that they want to be with you．Since you're not there，they need to find you．Dogs may suddenly develop separation anxiety．But with practice and patience(耐心)，you can teach your dog to be comfortable being left alone．

    Put on your jacket，and then sit down．After a while，walk out the door for 1 minute，then 2 and so on．Little by little your dog will learn that when you leave，you will return．

    Teach your dog a word or action that you use every time you leave，which tells your dog you'll be back．

    ·Before you leave，give your dog a toy(玩具).It will keep him busy while you're away．
