Signs of Illness in a Dog

No matter how well you know your dog, he can’t tell you how he feels, so you may not notice right away when he’s ill. However, if you’re familiar with his usual behaviour and appearance, you’ll be more aware when changes occur that may warrant veterinary help.

A trip to the veterinarian is in order if you observe the following symptoms:

  • Loss of appetite for several consecutive days
  • Lameness
  • Blood in the urine
  • A hair coat with harsh feel or dull texture
  • Mucus or blood in the stool
  • Foul-smelling stools
  • Loose stools
  • Repeated vomiting over several days
  • A potbelly or marked loss of weight
  • A “bloated” or distended belly that’s firm to the touch
  • Lack of interest in the doings around him
  • Hiding in dark places
  • Persistent coughing; discharge from the eyes or nose
  • Scratching or chewing at feet, skin, or hair coat
  • Shaking head, scratching ears
  • Yellowing of the white around the eye; yellow gums
  • Dehydration
