At my most recent Colorado Dog Trainers Network meeting, we were fortunate enough to have Christine Hardy , DVM, MBA, MPH from the CSU Animal Cancer Center speak with us about cancer in dogs and cats.

She provided us with the Top Ten Warning Signs of Cancer in Pet Animals:

  1. Abnormal swellings that persist or continue to grow.
  2. Sores that do not heal.
  3. Weight loss
  4. Loss of appetite
  5. Bleeding or discharge from any body opening
  6. Offensive odor
  7. Difficulty eating or swallowing
  8. Hesitation to exercise or loss of stamina
  9. Persistent lameness
  10. Difficulty breathing, urinating, or defecating

Many of these signs can be due to issues other than cancer, but if you notice any of these signs, it’s a good idea to see your veterinarian.
