Dog flu, or canine influenza, can present with various symptoms that may resemble those of a common cold or flu in humans. Here are some common symptoms to watch for:

1. **Coughing**: A frequent, dry cough is one of the most prevalent signs of dog flu. It may sound similar to a honking noise.

2. **Sneezing**: Dogs may sneeze more than usual, indicating irritation in the respiratory tract.

3. **Nasal Discharge**: You may notice a clear or colored discharge coming from your dog's nose.

4. **Fever**: A dog with the flu may have a higher than normal body temperature. A fever in dogs is generally considered to be above 102.5°F (39.2°C).

5. **Lethargy**: Affected dogs may show signs of fatigue or reduced energy levels, becoming less active than usual.

6. **Loss of Appetite**: Dogs with flu may not want to eat or drink, which can lead to dehydration if not monitored.

7. **Difficulty Breathing**: In more severe cases, dogs might exhibit labored breathing or wheezing.

If you notice these symptoms in your dog, it's essential to consult your veterinarian for a proper diagnosis and treatment plan. Early intervention can help prevent complications and ensure your dog recovers quickly. Additionally, keeping your dog away from other dogs during illness can help prevent the spread of the virus.
