Introduction
Canine influenza is an extremely contagious virus, and to date there are no vaccines available that will protect dogs from canine influenza. Early diagnosis and treatment drastically increases the chances of a complete and successful recovery. Early diagnosis and treatment can also help to prevent the further spread of canine influenza virus.
Symptoms of Canine Influenza
Symptoms of canine influenza often appear suddenly, and the severity of the symptoms depends on how the virus affected the dog. Many dogs experience mild symptoms of canine influenza such as a persistent cough, which can last for up to three weeks, in addition to yellow-green nasal discharge. The cough is sometimes confused with a condition known as kennel cough. In about 20 percent of canine influenza cases, dogs may not show any symptoms at all or the symptoms may be so slight they are missed completely.
Severe Canine Influenza
In some severe cases, dogs with canine influenza may experience the following:
- High fever
- Lethargy
- Depression
- Increased respiratory rate
- Loss of appetite
- Secondary infections such as pneumonia may develop if medical treatments are not administered
While the fatality rate for this virus is low, antibiotic medications are needed to control secondary infections and prevent further infection from developing.
If your dog shows any symptoms of canine influenza, particularly a sudden and persistent cough, contact your veterinarian immediately. As this virus is highly contagious, other dogs in the household are at risk for developing the disease. Until you find out what is causing your dog’s symptoms, try to keep your dog isolated from other dogs and always wash your hands thoroughly after petting or treating your dog.
