Plain-English summary
Seven Collies, both male and female, showed signs of Horner's syndrome, which included a droopy eyelid, a smaller pupil, and a third eyelid that was more visible. After thorough examinations and tests, including blood work and imaging, the exact cause of their symptoms couldn't be determined. However, treatment with a medication called phenylephrine helped improve their condition within 20 to 40 minutes. Most of the dogs fully recovered within 4 to 16 weeks after their symptoms first appeared.

Abstract
Seven cases of idiopathic Horner’s Syndrome in the Collie are described. Five males and two females presented with unilateral miosis, ptosis of the upper eyelid, enophthalmos and protrusion of the third eyelid. Thorough examination, pharmacological testing with phenylephrine, complete blood counts and radiography of the tympanic bullae and thorax were performed. The etiology was not identified in any of the cases. Clinical signs improved with pharmacologic testing within 20–40 min. In five dogs, total resolution of clinical signs was observed at 4 and 16 weeks after their initial appearance. Pharmacological testing suggested that the deficit could be at the preganglionic neuron.
