Signs that your dog is sick

Changes in Appetite: A sudden loss of appetite or a significant increase in food consumption can be a sign of illness. 

Vomiting or Diarrhea: Occasional vomiting or diarrhea can be normal, but if it persists or is accompanied by blood, mucus, or a change in color, it's a cause for concern. 

Lethargy: If your normally active dog becomes lethargic, lacks energy, or seems excessively tired, it could be a sign of illness. 

Coughing or Sneezing: Persistent coughing, sneezing, or nasal discharge may indicate a respiratory infection or allergy. 

Changes in Thirst or Urination: An increase in thirst and urination can be a sign of diabetes or kidney disease, while a decrease may indicate dehydration or other health issues. 

Fever: Dogs can develop a fever when they are sick. You can check for a fever by using a rectal thermometer.
