Why is my outdoor Blue Heeler lethargic, breathing hard, discharge?

Updated On September 23rd, 2025

Pet's info: Dog | Blue Heeler | Female | spayed | 8 years and 5 months old | 35 lbs

Outside Blue Heeler, lost long time companion dog 2 weeks ago, nasal discharge, yellow thick eye discharge, weight loss, seems to be heavy breathing-has been 90's deg weather and humid, depressed, hasn't shed, seems stiff when walking. Responds and follows me but just seems lethargic, no excitement, doesn't run, just lays around. Wormed for roundworms 2 days ago, worming for tapes today.

There are several different things that I would be concerned about. It seems that she has sumptims of a respiratory infection with the eye and nasal discharge. This may be also causing the heavier breathing. However, with any outdoor dog, if she has not been diligently kept up to date on heart worm prevention- this could be a cause. This requires a blood test to diagnose. The stiffness, lack of energy may be stemming from the other issues, but she also maybe suffering from arthritis, tick borne diseases, or other generalized infections. It is important to take her to a veterinarian for a work up ASAP. I really don’t think that deworming her for intestinal parasites is going to make any difference.
