The howling of an Alaskan wolf represents boredom, loneliness, hunger, dissatisfaction, or physical discomfort. Under normal circumstances, Alaskan wolves will not howl casually, so when a dog howls, carefully observe whether there is any abnormality in the dog's body. If the dog has symptoms such as poor energy, vomiting and diarrhea, it is best to go to the pet hospital for examination immediately; if the dog has no abnormal symptoms, you can spend more time with the dog.
