What exactly is Horner syndrome in dogs and how do I know if that's what my dog has?

I've noticed some odd changes in my dog's eyes and face recently, like drooping of the eyelid and a smaller pupil in one eye. I stumbled across something called Horner syndrome online and I'm worried that these could be the signs. Can you explain more about what Horner syndrome is in dogs and how I can tell if that's what's affecting my dog?

Answer

It can be concerning to notice changes in your dog's eyes and face. Horner syndrome could be the cause, characterized by drooping eyelids, a smaller pupil in one eye, and other symptoms.

  • Recognizable symptoms include drooping of the eyelid and a smaller pupil.
  • Horner syndrome often affects one side of the face.
  • Consult a vet to confirm diagnosis and cause.

Horner syndrome in dogs is a neurological condition caused by disruption of the sympathetic nerves supplying the eyes and facial muscles. Symptoms can include a drooping eyelid, constricted pupil, sunken appearance of the eye, and a lack of sweating on the affected side of the face. These signs usually appear suddenly and may be due to underlying issues such as injury, inflammation, or tumors. It's important to get a veterinary examination to determine the precise cause and appropriate treatment for your pet.
