Horner’s syndrome in dogs, also known as oculosympathetic syndrome, is a neurological disorder affecting the eye and surrounding facial muscles. While not typically painful, Horner’s syndrome can be a symptom of a more serious underlying health issue. This comprehensive guide delves into the causes, symptoms, diagnosis, and treatment of Horner’s syndrome in dogs, empowering owners with the knowledge to recognize and address this condition.
Understanding Horner’s Syndrome in Dogs
Horner’s syndrome disrupts the nerve pathways that control certain eye and facial functions. This disruption results in a characteristic set of symptoms, most noticeably affecting one side of the dog’s face. The condition can affect dogs of any breed, age, or size. Recognizing the signs early is crucial for determining the underlying cause and implementing appropriate treatment.
Identifying the Symptoms of Horner’s Syndrome

- Miosis (Constricted Pupil): The affected pupil appears smaller than the pupil in the other eye.
- Ptosis (Drooping Eyelid): The upper eyelid on the affected side droops, partially covering the eye.
- Enophthalmos (Sunken Eye): The eye on the affected side may appear sunken or recessed into the eye socket.
- Protrusion of the Third Eyelid: The third eyelid, located in the inner corner of the eye, becomes more visible and may partially cover the eye.
- Changes in Facial Sweating: In some cases, the affected side of the face may have reduced sweating or changes in skin temperature.
