Overview of Canine Influenza
Canine influenza, also known as dog flu, is a contagious respiratory disease that affects canines. There are two main types of canine influenza: H3N8 and H3N2. The H3N8 strain was first identified in the United States in 2004 and is believed to have originated from horses. The H3N2 strain emerged in 2015 and is of avian origin. Both types of canine influenza can cause mild to severe respiratory symptoms in dogs.
Types of Canine Influenza
Canine influenza is caused by two different types of influenza viruses: H3N8 and H3N2. The H3N8 strain was initially a horse influenza virus that was able to adapt and transfer to dogs. The H3N2 strain is believed to have originated in Asia and is of avian origin. Both strains can cause similar clinical signs and symptoms in dogs, including coughing, sneezing, nasal discharge, lethargy, and fever.
Transmission of Canine Influenza
Canine influenza is highly contagious and can spread easily among dogs. The virus is primarily transmitted through respiratory secretions from infected dogs. When an infected dog coughs or sneezes, the virus becomes airborne and can be inhaled by other dogs in close proximity. The virus can also be transmitted indirectly through contact with contaminated surfaces such as food and water bowls, toys, and clothing. Additionally, humans can inadvertently transmit the virus from one dog to another if they come into contact with an infected dog and then touch or handle another dog without proper hand hygiene.
Symptoms of Canine Influenza
Dogs infected with canine influenza may show a range of symptoms. The most common signs include coughing, sneezing, nasal discharge, lethargy, and fever. Some dogs may also experience a reduced appetite, difficulty breathing, or have a moist or dry cough. In some cases, severe complications such as pneumonia can arise, especially in dogs with weakened immune systems or underlying health conditions. It is important to note that while most dogs recover from canine influenza within two to three weeks, some may develop more severe illness or complications.
