Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to stop howling dogs [title] Ignore your dog's howling. [step] Some dogs will howl in order to get your attention, or to " ask " for food, treats, toys, etc. To prevent this kind of howling behavior, you will first have to show your dog that howling is not a way to get your attention.

Ending1: [substeps] Don't scold or punish your dog when it howls, as it may find even this kind of attention rewarding. Simply do not touch, speak, or look at your dog when it howls to get your attention. Ending2: Yelling back to your dog may just make him think that you are too busy to respond to his howling. Plus, yelling back won't give him any effect. Ending3: [substeps] Yelling or hitting your dog will only cause it to howl. Ignoring, however, is best done in conjunction with its howling behavior. Ending4: You will also have to stop and listen to your dog carefully as it is howling. [substeps] Make sure that you are between the dog and two people in a car or apartment building when your dog yelps.
