Signs of Illness or Disease

Dogs and cats need people who know what to look for to make sure they are in good health. Older animals may need specialized care and animal owners need to be aware when it is time to euthanize an animal, to relieve pain and prevent suffering. 

Some visible signs of illness to watch for in a dog or cat are:

  • Weight loss or gain.
  • Drinking excessively or not at all.
  • Lack of appetite.
  • Vomiting.
  • Diarrhea.
  • Lethargy (lack of energy, disinterest in toys, play and exercise). 
  • Loss of coordination, circling, paralysis.
  • Cloudy discharge from eyes/nose.
  • Increased heart rate and respiratory rate.
