Dog With A Dry Cough And Dry Heaving. The condition of dry cough is entirely different from heaving. However, all pet owners do not vaccinate their dogs as they should, so distemper can be a reason for an unproductive dry cough and dry heaving.

Robitussin dm at a 1/4 teaspoon per 5 pounds can be used to control the cough. Dogs with kennel cough should be quarantined from other canines to prevent the spread of this disease. It’s your dog’s normal response to irritation, the same as you coughing or clearing your throat.
