Ehrlichiosis is a serious tick-borne disease caused by the Ehrlichia bacterium, primarily affecting dogs but also seen in cats. This illness can lead to severe health complications if not detected and treated early. Here’s a concise guide to help you protect your pet.
✅ What is Ehrlichiosis?
Ehrlichiosis is transmitted through the bite of infected ticks, most commonly the Brown Dog Tick (Rhipicephalus sanguineus). Once infected, the bacteria attack white blood cells, weakening the immune system and leaving pets vulnerable to further illnesses.
🚨 Symptoms to Watch For
Symptoms vary depending on the stage of infection:
- Early Stage (Acute): Fever, lethargy, swollen lymph nodes, and loss of appetite.
- Subclinical Stage: Often symptomless but still dangerous, silently weakening the body.
- Advanced Stage (Chronic): Weight loss, anemia, bleeding disorders, lameness, and possible organ failure.
🩺 Diagnosis and Treatment
Veterinarians diagnose Ehrlichiosis through blood tests, including PCR testing. Treatment typically involves antibiotics such as Doxycycline. Most pets recover well if treated early, but severe cases may require hospitalization, supportive care, and ongoing monitoring.
🤔 How to Prevent Ehrlichiosis
- Use vet-approved tick prevention products year-round.
- Regularly check your pet for ticks, especially after outdoor activities.
- Keep your yard tidy and free of tall grasses and leaf litter where ticks thrive.
- Schedule routine veterinary check-ups to catch potential infections early.
- Consider blood tests twice a year to detect subclinical infections before symptoms appear.
