3. **Vomiting or Diarrhea**: Occasional vomiting or diarrhea can be normal, but if it persists or is accompanied by other symptoms, it could indicate a health issue.
4. **Changes in Drinking Habits**: Drinking more or less water than usual can be a sign of various health problems. Pay attention to any significant changes.
5. **Coughing or Difficulty Breathing**: Persistent coughing, wheezing, or labored breathing can indicate respiratory issues and should be evaluated by a vet.
6. **Behavioral Changes**: If your dog is more aggressive, anxious, or withdrawn than usual, it may be experiencing discomfort or pain.
