Observe the mental state and physical condition of the Australian Shepherd. If the dog coughs along with sneezing and runny nose, it is a seasonal cold. It is not serious and only needs to be treated with cold medicine and anti-inflammatory drugs. That’s it; if the dog has difficulty breathing and decreased energy while coughing, it is an internal disease caused by respiratory disease, cardiopulmonary and vascular diseases, and the owner should send the Australian Shepherd to a nearby pet hospital for treatment.
