If you dream of a dog, it might be a good sign if they are behaving and listening to you, especially if it is a puppy. However, if the dog is misbehaving, fighting or breaking things, it may mean that you will have trouble in your life soon, especially from untrustworthy people. If the dog bites you, then there could be someone out to get you. If dogs are barking or howling, it might mean illness or death in your family.
