1. Bad breath: Healthy Australian Terriers generally do not have bad breath. If there is an abnormal smell, it is a sign of illness. Generally, there are dental problems such as periodontal disease, and there are also problems with internal organs.

2. Diarrhea or vomiting: If the Australian Terrier continues to vomit or have diarrhea several times a day , should draw attention. Common causes include gastrointestinal diseases, as well as internal parasitic diseases such as roundworms, whipworms, and hookworms.

3. Cough: Australian Terriers who have persistent cough should also see a veterinarian, as it may be a symptom of heart disease, lung disease or heartworm disease.
