Pseudorabies (Aujeszky's Disease) in Dogs

Pseudorabies is a highly fatal viral disease caused by a herpes virus. Also referred to as Aujeszky's disease, this disease is usually associated with contact with swine (pigs) but can also be acquired by ingesting infected rats or eating contaminated, uncooked pork. For this reason, pseudorabies is more commonly seen in dogs that live on farms.

What to Watch For

Sudden change in behavior

Excessive salivation

Difficult or rapid breathing

Fever

Vomiting

Depression

Lethargy

Ataxia (difficulty walking due to poor coordination)

Convulsions

Reluctance to move

Intense pruritis (itching)

Self mutilation

Coma

Sudden death

This disease progresses rapidly, and death usually occurs within 48 hours.

Diagnosis

Compatible clinical signs and recent exposure to pigs is highly suggestive of pseudorabies infection. Baseline tests to include a complete blood count (CBC), biochemical profile, and urinalysis are recommended in all patients, and are often within normal limits. Additional tests may include:

Serologic testing. Blood tests that measure antibodies or the bodies response to an organism are the most frequent tests used to diagnose pseudorabies – if the animal recovers.

Antibody testing on brain tissue to test the body's microscopic response to an organism

Isolation of the viral organism

Treatment

There is no known effective treatment. Supportive care and prevention of self-injury is indicated. Death is the expected outcome.

Home Care and Prevention

There is mild potential for human infection. Take precautions when treating or handling infected dogs. Dog-to-dog transmission is unusual.

Preventing pseudorabies is aimed at avoidance of contaminated swine. Also, avoiding ingestion of raw or contaminated pork and infected rats is highly recommended.
