The most common sign of dog flu is a persistent cough.
Some dogs have a soft, moist, “productive” cough, while others have a dry cough similar to that seen in dogs with canine cough—a respiratory condition that is caused by any of a number of other viruses and bacteria.

This similarity can make it hard for your veterinarian to diagnose which illness your dog has. About 80% of dogs that show signs will have a mild flu.

Signs in this case include:

- a low-grade fever
- runny nose
- lack of energy
- loss of appetite
- a cough that can last for up to a month

Usually mild, dog flu can become quite serious in about 20% of the cases,
with a high fever (104°F to 106°F) and pneumonia.
A small number of dogs have died from complications associated with the illness.
