Dogs that howl excessively when their owners are not at home are most likely experiencing separation anxiety. As pack animals, canines frequently feel significant anxiety when left alone. Dogs also howl in response to other howling dogs that are within their range of hearing. That range is usually far greater than the hearing range of humans. Train horns, sirens and certain musical instruments may also invoke a dog's howl.
Pet owners whose dogs howl excessively should first rule out any type of medical condition that may cause the animal to attempt to communicate distress through howling. A professional dog trainer can help identify and address all other forms of excessive howling.Learn more about Dogs
