Horners syndrome is a rare condition that may affect canines, causing lack of control over the facial muscles. The facial muscles are controlled by the sympathetic nerves and when these are affected, the dog may display some unusual symptoms. The condition is treatable if the causes are detected and dealt with. Causes of Horners Syndrome Horner's syndrome in dogs occurs when a nerve going from the eye to the brain has been damaged. There are three things that can happen to cause the damage to the nerve In dogs, about half the cases of Horner's syndrome are idiopathic, meaning it has an no known cause. In cats, however, a cause is virtually always found, and idiopathic Horner's syndrome is very rare. With many cats that develop Horner's syndrome, there is a recent history of trauma, particularly being hit by a car Approximately 50% of dogs with sympathetic dysfunction (commonly termed Horner's syndrome) are diagnosed with idiopathic dysfunction. 3 The lesion may be located in the second or third order sympathetic neuron based on pharmacologic testing. 4-6 No treatment is indicated for these animals and many spontaneously recover.
Horner syndrome causes ptosis, miosis, and anhidrosis. It results from a central or peripheral lesion (preganglionic or postganglionic) that disrupts the cervical sympathetic pathway, which runs from the hypothalamus to the eye In general, Horner syndrome is a neurological condition of the facial muscles and eye that commonly happens in dogs, horses, cats, and many other pets.

Damage to these nerves anywhere along the pathway can lead to the parasympathetic nervous system taking over the normal functions of the sympathetic nervous system. Horner's Syndrome Average Cost.

.In dogs, Horner's Syndrome is 'idiopathic', which means it has an unknown cause, in about half the cases collis, ipsilateral Horner's syndrome, enophthalmia, and paradoxical vestibular syndrome.3,5-8 The auditory tube is controlled by the tensor tympani and tensor veli palatini muscles innervated by the trigeminal nerve and the levator veli palatini and salpingopharyngeus muscles innervated by the vagus nerve. Trigeminal nerve lesions therefore als Otitis media, an inflammatory disease process affecting the middle ear, is a frequent ailment recognized in small animal veterinary practices in both canine and feline patients. It results in damage to the tympanic membrane and bulla and a variety of clinical signs ranging from pain to vestibular signs. Otitis media can stem from either primary. Damage to this nerve can occur during overzealous cleaning by owners and can lead to a specific condition called Horner's Syndrome. In both dogs and cats, bite/fight wounds, burns and vehicular trauma can lead to secondary infections. Cats are more likely to have parasitic infestations due to the ear (Otodectes sp.) mites than dogs are Among children that experience relatively minor post-vaccination acute type 1 hypersensitivity reactions (e.g., angioedema), the risk of an adverse reaction tends to decrease with age. It is not known if this consistently occurs in dogs. Dogs experiencing a severe, type 1 hypersensitivity reaction (e.g., systemic anaphylaxis) must be monitored.
