Vestibular Disease in Dogs: Symptoms and Treatment
It’s understandably frightening when your dog suddenly develops symptoms of vestibular disease, such as head tilt, loss of balance, or rapid eye movements, because these symptoms can resemble a stroke or neurologic emergency. Luckily, while canine vestibular disease can have a very dramatic appearance, most cases tend to improve significantly with supportive care, time, and patience.
Here, we’ll answer your questions about vestibular disease in dogs.
Q1: What is vestibular disease in dogs?
The dog’s vestibular system, which involves the brain and the structures of the inner ear, controls the dog’s balance, coordination, and spatial orientation.
When the vestibular system becomes disrupted, the dog develops vestibular disease. With peripheral vestibular disease, the structures of the inner ear are affected. With central vestibular disease, the issue involves the brain.
When the cause is unknown, the condition is called idiopathic vestibular syndrome in dogs. Idiopathic vestibular disease is the most common form of vestibular disease in dogs, especially middle-aged to older dogs. For this reason, it’s sometimes called old dog vestibular syndrome.
Q2: What are the symptoms of vestibular disease in dogs?
Symptoms of vestibular disease in dogs often appear suddenly, so they can be quite frightening for pet parent and dog alike.
These symptoms include:
- Head tilt
- Loss of balance or falling over
- Circling or stumbling
- Rapid eye movements (nystagmus)
- Difficulty standing or walking
- Nausea or vomiting from dizziness
With central vestibular disease, the dog may appear depressed or stuporous. Occasionally, they may be comatose. This is because the brain is affected.
With peripheral vestibular disease, the dog is usually alert and responsive even though they appear disoriented.
Q3: What causes vestibular disease in dogs?
In most cases, especially in senior dogs, the exact cause of vestibular disease isn’t known. In these cases, the dog usually has idiopathic vestibular disease or old dog vestibular disease.
Other causes of vestibular disease in dogs include:
- Inner ear infections
- Tumors within the ear or brain
- Conditions causing brain inflammation, such as meningoencephalitis of unknown origin (MUO)
- Certain infections, like canine distemper virus or tickborne rickettsial diseases
- Traumatic injuries
- Certain medications that are toxic to the ear
- Hypothyroidism
The veterinarian may recommend testing (more on this in the next section) to determine the cause and rule out more serious underlying conditions.
Q4: How is vestibular disease diagnosed?
The veterinarian will perform a complete physical and neurological examination. During the neurological examination, they’ll look at your dog’s nerve responses, reflexes, and gait. This can help differentiate peripheral vestibular disease from central vestibular disease.
Diagnostics that may be recommended include:
- Bloodwork to assess overall health
- Testing for tickborne diseases
- Ear examination to rule out infection
- Skull x-rays
- Imaging such as MRI or CT scan
- Cerebrospinal fluid analysis
Not every dog will require advanced testing. The veterinarian is more likely to recommend advanced testing if your dog shows no improvement or has worsening signs, if the signs appear to be brain-related (central vestibular disease), or if signs are recurrent.
Q5: How is vestibular disease treated?
Treatment will depend on the underlying cause.
If your dog has idiopathic vestibular disease, supportive care is the mainstay of treatment. Most dogs will improve over 1 to 2 weeks, and no specific treatment appears to speed recovery. Antinausea medications and anti-anxiety medications may be recommended.
Make sure to consider your dog’s safety in the home! They’re at risk of falling, so stairs and heights should be avoided.
Inner ear infections are usually treated with antibiotics and/or antifungals for 6 to 8 weeks. In some cases, surgery is required to manage inner ear infections.
Some tumors may be surgically removed. For others, radiation therapy can provide relief. In these cases, your pet may be referred to a specialist, either in cancer (oncology) and/or surgery.
Some infections, such as tickborne rickettsial diseases like ehrlichiosis, are treated with antibiotics (e.g., doxycycline). Fungal infections require antifungals like fluconazole. Inflammatory or autoimmune conditions may respond to immunosuppressants. Dogs with hypothyroidism usually need levothyroxine to treat their condition.
Q6: What is the recovery and prognosis for dogs with vestibular disease?
Dogs with idiopathic vestibular disease usually have a good prognosis and begin to show improvement within several days to weeks. You’ll need to protect your dog from fall injuries, and your veterinarian may recommend antinausea or anti-anxiety medications to help keep them comfortable.
Most causes of peripheral vestibular disease—except cancer—come with a good prognosis, but treatment may take a while. Inner ear infections will need to be treated for 6 to 8 weeks.
Brain-related causes usually have a worse prognosis. Some may show improvement with treatment, but the signs are likely to recur or worsen over time.
If your dog’s symptoms worsen or do not improve within a week or two, seek follow-up care. Remember, although vestibular disease may look dramatic, many dogs recover and regain a good quality of life.
While vestibular disease often comes on suddenly and is quite alarming, many cases will improve with time and supportive care. Your veterinarian can help identify the cause of your dog’s vestibular symptoms and whether more targeted treatments are necessary. If you’re noticing balance problems or neurological symptoms, make sure to contact your veterinarian promptly to get a diagnosis. Most dogs with vestibular disease have idiopathic vestibular disease, and these dogs generally recover comfortably and continue to enjoy a good quality of life.
