1. **Changes in Appetite**: If your dog suddenly loses interest in food or shows increased hunger, it could be a sign of underlying health issues.

3. **Vomiting or Diarrhea**: Occasional vomiting or diarrhea can happen, but if it persists for more than 24 hours or is accompanied by other symptoms, it’s time for a vet visit.
4. **Coughing or Difficulty Breathing**: Persistent coughing or any signs of respiratory distress, such as wheezing or labored breathing, should be evaluated by a vet.
5. **Changes in Urination**: If your dog is urinating more frequently, straining to urinate, or having accidents in the house, it could indicate a urinary tract infection or other issues.
6. **Unusual Behavior**: Any sudden changes in behavior, such as increased aggression, hiding, or excessive barking, can signal health problems.
7. **Weight Changes**: Sudden weight loss or gain can be a sign of health issues, such as diabetes or thyroid problems.
8. **Skin Issues**: Persistent itching, redness, swelling, or the presence of lumps or bumps on the skin should be checked by a vet.
9. **Joint Pain or Difficulty Moving**: If your dog is limping, showing reluctance to jump, or has difficulty getting up, it may be suffering from arthritis or an injury.
10. **Bad Breath**: While dogs can have a natural odor, extremely foul breath can indicate dental disease or other health issues.
