This episode explains ehrlichiosis, a serious tick-borne disease newly established in parts of Australia. The discussion covers what the disease is, how it spreads, the regions at highest risk, the symptoms owners should watch for, how vets diagnose it, and why prevention and early treatment are essential for protecting dogs.
Podcast Summary: Understanding Ehrlichiosis in Dogs
- Ehrlichiosis is a blood-borne bacterial infection spread by the brown dog tick; dogs, dingoes, and foxes can all be affected.
- The disease was first detected in Australia in 2020 and is now established in the NT and northern WA, with emerging cases in remote regions.
- Brown dog ticks thrive in warm, dry climates — especially northern Australia — and dogs can pick up hundreds in heavily infested areas.
- Ehrlichia bacteria live inside white blood cells and can cause acute illness, chronic disease, or subclinical infection with no early symptoms.
- Symptoms vary widely and can include fever, lethargy, enlarged lymph nodes, bleeding disorders, bruising, nosebleeds, anaemia, and weight loss.
- Because symptoms mimic many other illnesses, vets must request specific laboratory testing (PCR or antibody tests) to confirm infection.
- Some dogs clear the infection naturally, but others develop chronic disease weeks to months later, including kidney and liver complications.
- Certain breeds such as German Shepherds and Dobermans may be genetically more prone to severe disease.
- Ehrlichiosis is treatable with a long course of antibiotics if caught early; severe cases may require blood or plasma transfusions.
- Prevention is critical — the infection occurs immediately when an infected tick bites, so fast-kill tick control and repellents are essential.
- Travelling dogs must be protected before entering high-risk regions, and WA has movement restrictions requiring documented tick prevention.
- Daily tick checks remain important, especially when travelling to northern or inland regions with known brown dog tick populations.
