Why is my dog circling, lethargic, and eating grass? Should I worry?

Updated On September 23rd, 2025

My Labradoodle who is 9 y.o. is having a second episode of an odd movement where she turns left in a circle and her head stays looking left when she walks. She is also lethargic and not excited about her usual treat in the morning. We noticed she has been eating grass at least for a couple of days, but this unusual behavior started last evening. She was playing and energetic at the dog park day before yesterday. Also, this has happened once before and went away, thinking gone in 24 hours.

That is unusual behavior. I recommend to have Sandy examined by her veterinarian today. Also try to record the behavior before your visit so that the veterinarian can see it as well. The most common causes for a pet to exhibit this abnormal movement are inner ear infections, damage to ear drum or a foreign object stuck in the ear. Other potential causes that would be less common would be meningitis, an infection in the nervous system, a brain tumor, toxin ingestion or canine vestibular disease. The doctor will perform a thorough physical exam. They will try to determine if there is any signs of neurologic involvement and check the ear canals very well. From there they may recommend further diagnostics depending upon the physical exam findings. I hope she gets back to her regular self quickly and please feel free to post any additional questions.
