Stroke

Symptoms of a stroke in dogs

The symptoms of a stroke in dogs can vary depending on the type and severity of the stroke. There are two main types of strokes: ischemic and hemorrhagic. An ischemic stroke occurs when a blood clot or other blockage prevents blood flow to a part of the brain. A hemorrhagic stroke occurs when a blood vessel in the brain ruptures or bursts, causing bleeding.

The most common symptoms of a stroke in dogs are

• Head tilt
• Impaired balance or coordination
• Weakness or paralysis of one side of the body
• Disorientation or confusion
• Vomiting or nausea
• Visual disturbances or blindness
• Loss of consciousness or coma

If you notice one or more of these symptoms in your dog, you should see a vet immediately, as a stroke is a life-threatening emergency.

Causes and risk factors for a stroke in dogs

The exact causes of stroke in dogs are often unknown, but there are some factors that can increase the risk. These include:

• Age: Older dogs are more prone to strokes than younger ones.
• Pre-existing conditions: Conditions such as diabetes, kidney failure, heart disease, high blood pressure, Cushing's syndrome or cancer can increase the risk of stroke.
• Medications: Some medications, such as steroids, anticoagulants or chemotherapy, can affect blood clotting and increase the risk of stroke.
• Trauma: A head injury or shock can lead to a stroke.
• Infections: Bacterial or viral infections, such as leptospirosis, ehrlichiosis or distemper, can cause inflammation in the brain and trigger a stroke.

Treatment of a stroke in dogs

The treatment of a stroke in dogs depends on the type and extent of the damage. The vet will first carry out a thorough examination to confirm the diagnosis and determine the cause. This may include blood tests, x-rays, ultrasound or a magnetic resonance imaging (MRI) scan.

Treatment aims to restore the blood supply to the brain, stop the bleeding, reduce the inflammation and treat the underlying cause. This may include the following measures:

• Oxygen therapy: to increase oxygen levels in the blood to supply the brain.
• Fluid therapy : To stabilize blood pressure and prevent dehydration.
• Medication: To regulate blood clotting, stop bleeding, relieve inflammation or fight infection.
• Surgery : In rare cases, surgery may be necessary to remove a blood clot or stop bleeding.

The prognosis for a dog after a stroke depends on the severity and location of the damage. Some dogs may make a full recovery, while others may have permanent neurological deficits. Recovery can take weeks or months and requires intensive care and rehabilitation.

Preventing a stroke in dogs

There is no guarantee that a stroke in dogs can be prevented, but there are some steps you can take to reduce the risk. These include:

• Regular vet visits: to check and treat your dog for possible diseases that can cause a stroke.
• Healthy diet : To provide your dog with all the nutrients they need for a healthy heart and brain.
• Adequate exercise: To keep your dog fit and active and prevent obesity, high blood pressure or diabetes.
• Stress reduction : To protect your dog from anxiety or shock, which can trigger a stroke.
