What are the main symptoms of canine influenza virus?

Canine influenza virus, also known as dog flu, is an infectious respiratory disease caused by influenza A viruses. There are two primary strains affecting dogs in the United States: H3N8 (originating from horses) and H3N2 (originating from birds). Here are the key symptoms associated with canine influenza:

  1. Cough: Dogs with flu may develop a persistent cough that can last 10 to 30 days. This cough often does not respond well to antibiotic or cough suppressant therapy.
  2. Runny Nose: Some infected dogs experience a greenish nasal discharge.
  3. Fever: Elevated body temperature is common during the illness.
  4. Eye Discharge: Dogs may have goopy or mucus-like eye discharge.
  5. Reduced Appetite: A decrease in appetite is observed in many cases.
  6. Lethargy: Severe illness can lead to lethargy, indicating a more critical condition.
  7. Trouble Breathing: Difficulty breathing may occur in severe cases.

It’s essential to note that not all dogs infected with the virus show symptoms. Approximately 20-25% of infected dogs remain asymptomatic but can still spread the disease. Canine influenza spreads through respiratory secretions, contaminated objects, and close contact with infected dogs. Isolation and quarantine measures are recommended to prevent transmission ¹²³. If you suspect your dog has flu-like symptoms, consult your veterinarian promptly or get tested using a rapid test product. 🐾.
