Q. I got a Golden Retriever age 11. got diagnosed with Horner’s Syndrome but has yet to find the issue, so far blood test normal except hypothyroidism

Answered By
DAVID ELBEZE, DVM, MRCVS

A. Approximately 40-50% of the cases of Horner's Syndrome in dogs are idiopathic, which means we might never know what is the cause. if this is the only symptom your dog has, it might remain like that or get better with time, but the cause might never be found.

other possible reasons for Horner's:

Bite wounds
Intervertebral (IV) disc disease in the neck area
Infections of the middle ear
Disease of the orbit (area behind the eye)
Cancer involving the brain or chest
As a result of a treatment (e.g.; ear cleaning) or medication
