Ehrlichiosis in dogs is a tick-borne disease caused by the bacterium Ehrlichia canis. This disease is primarily transmitted through the bite of an infected brown dog tick (Rhipicephalus sanguineus).

Symptoms

Dogs infected with Ehrlichia canis may exhibit a variety of symptoms, which can be categorized into three stages: acute, subclinical, and chronic.

• Acute stage: This stage occurs 1-3 weeks after the tick bite. Symptoms include fever, lethargy, swollen lymph nodes, and bleeding disorders such as nosebleeds or bruising.
• Subclinical stage: In this stage, the dog may appear healthy, but the infection persists in the body. This stage can last for months or even years.
• Chronic stage: Dogs may develop more severe symptoms such as weight loss, anemia, neurological signs, and severe bleeding disorders.

Diagnosis

Diagnosis of canine ehrlichiosis is typically made through a combination of clinical signs and laboratory tests. Blood tests such as a complete blood count (CBC) and serology can indicate infection. Polymerase chain reaction (PCR) tests can confirm the presence of Ehrlichia canis DNA in the blood.

Treatment

The primary treatment for ehrlichiosis in dogs is the administration of antibiotics, with doxycycline being the most commonly used. Treatment usually lasts for several weeks. Supportive care may also be necessary for dogs with severe symptoms.

Prevention

Preventing ehrlichiosis involves controlling tick exposure. This can be achieved through the use of tick prevention products, regular tick checks, and maintaining a tick-free environment.
