1. **Coughing**: A persistent cough is often one of the first signs. It may sound dry or wet, and you might notice your dog coughing more often, especially after exercise or during excitement.
2. **Nasal Discharge**: Look for any discharge from the nose. It can be clear, cloudy, or even colored, depending on the type of infection.
3. **Difficulty Breathing**: If your dog is breathing faster than usual or appears to be struggling to breathe, this is a serious sign that requires immediate veterinary attention.
4. **Lethargy**: If your dog seems unusually tired, less active, or is sleeping more than normal, this can indicate they are not feeling well.
5. **Loss of Appetite**: A decrease in appetite or refusal to eat can be a strong indicator of illness.
6. **Fever**: If you notice your dog feels warmer than usual or is shivering, they might have a fever. A vet can confirm this with a thermometer.
7. **Gagging or Retching**: Some dogs may gag or retch, which can be a sign of irritation in the throat or airway.
8. **Changes in Barking**: If your dog’s bark sounds hoarse or different, it could indicate a problem with their respiratory system.
If you observe any combination of these symptoms, it’s essential to consult with your veterinarian as soon as possible. Early diagnosis and treatment can prevent more serious complications. Treatments may include medications, rest, and supportive care, depending on the severity and type of infection.
