Plain-English summary
A 10-year-old Beagle was brought in for a droopy eyelid and a sunken eye on the right side of its face. The veterinarian diagnosed Horner's syndrome, a condition that can occur due to various underlying issues, including trauma or tumors. In this case, the cause of the syndrome was not determined, which is common, as the cause remains unknown in about half of the cases. Treatment options may vary depending on the underlying cause, but many pets can still lead normal lives despite the symptoms.

Abstract
The medical records of 74 dogs and 26 cats with Horner's syndrome (HS) that were admitted to the New York State College of Veterinary Medicine between January 1975 and October 1985 were reviewed. In dogs, but not cats, HS was associated significantly (P less than 0.01) with increasing age. Dogs with hypothyroidism (defined liberally but not rigorously), intracranial neoplasia, or thoracic neoplasia, cats with otitis media/interna (defined liberally), and dogs and cats with brachial plexus root avulsion were at greater risk for developing HS than were animals that were hit by a car. Dogs and cats with otitis externa were at less risk of developing HS than were animals that were hit by a car. The cause of HS could not be determined in 50% of dogs and 42.3% of cats. The results of topical adrenergic drug testing in dogs were inconclusive in localizing lesion site. In dogs and cats, HS appeared to be unassociated with gender, breed, or right vs left side. The important causes of HS in dogs and cats were trauma (hit by car), brachial plexus root avulsion, intracranial and thoracic neoplasia, and otitis media/interna.
