Canine Idiopathic Head Tremors (IHT): All You Need to Know

Canine idiopathic head tremors (IHT) is a neurological condition that causes involuntary, rhythmic shaking of the head in dogs. The condition is idiopathic, meaning that its exact cause is unknown. IHT typically affects dogs between the ages of 1 and 5 years, and it is more common in certain breeds, such as the Cavalier King Charles Spaniel, Maltese, and Yorkshire Terrier.

Symptoms of IHT

The most common symptom of IHT is head tremors. These tremors can be mild or severe, and they may be constant or intermittent. Other symptoms of IHT may include:

• Nystagmus (involuntary eye movements)
• Ataxia (difficulty walking or standing)
• Tremors in other parts of the body
• Seizures

Diagnosis of IHT

IHT is diagnosed based on the dog's clinical signs. There is no specific test for IHT, but your veterinarian may recommend blood tests, urine tests, or imaging studies to rule out other potential causes of the tremors.

Treatment of IHT

There is no cure for IHT, but the condition can be managed with medication. Medications that are commonly used to treat IHT include:

• Prednisone
• Cyclosporine
• Azathioprine

In some cases, surgery may be necessary to correct an underlying neurological abnormality that is causing the tremors.

Prognosis for IHT

The prognosis for dogs with IHT is generally good. Most dogs with IHT can live a normal life with medication. However, some dogs may experience progressive worsening of their symptoms over time.

How to Help Your Dog with IHT

If your dog has been diagnosed with IHT, there are a few things you can do to help manage the condition:

• Give your dog its medication as prescribed by your veterinarian.
• Keep your dog's environment calm and stress-free.
• Avoid activities that may trigger your dog's tremors, such as loud noises or sudden movements.
• Provide your dog with plenty of love and support.
