Vet’s 2025 Guide to Canine Stroke (Cerebrovascular Accident) 🧠🩺

By Dr. Duncan Houston BVSc

💡 What Is a Stroke in Dogs?

A canine stroke, or cerebrovascular accident (CVA), happens when a blood vessel in the brain is blocked (ischemic) or ruptures (hemorrhagic), interrupting oxygen flow. This impairs brain function, potentially leading to sudden neurological signs and serious outcomes if left untreated.

🚩 Why It’s an Emergency

• 🆘 A stroke is life-threatening—immediate veterinary attention is vital.
• ⏱️ Neurological damage stabilizes within 24–72 hours, so early intervention supports recovery.
• 🔎 Identifying underlying causes (e.g. heart disease, clotting disorders, cancer, endocrine disease) is crucial to prevent recurrence.

👀 When to Suspect a Stroke

Sudden onset of any of the following neurological signs could indicate a stroke:

• 🚶♂️ Sudden collapse or inability to stand.
• 🔄 Circling, falling to one side, or loss of balance/coordination.
• 🧠 Head tilt, compulsive pacing.
• 👁️ Abnormal eye movements or sudden blindness.
• ✋ Weakness or paralysis affecting one or more limbs.
• 🧩 Seizures, disorientation, abrupt behavior changes.
• 🚫 Loss of bladder/bowel control may occur in severe cases.

🔍 Diagnostic Process

1. Immediately assess and stabilize: physical and neurological exam, blood pressure, bloodwork (CBC, chem, clotting), urinalysis, chest X-ray.
2. Advanced imaging: MRI (preferred) or CT scan under anesthesia to confirm stroke and rule out tumors or bleeding.
3. Cardiac & systemic screening: ECG, echo, endocrine tests (thyroid, Cushing’s), blood pressure.
4. CSF analysis: used when infection or inflammation is suspected.

🛠 Treatment & Supportive Care

• 🏥 Hospitalization with IV fluids, oxygen support, seizure control, and intracranial pressure management if needed.
• 🩸 Anticoagulants like clopidogrel may reduce recurrence risk.
• 💊 Treat underlying disease: blood pressure abatement, endocrine control, cancer therapy.
• 🤸 Rehabilitation: physical therapy, range-of-motion exercises, slings, assistive devices.

📈 Recovery & Prognosis

• 🟢 Many dogs show significant improvement within weeks to months; first 30 days are critical.
• 🟡 Persistent deficits—such as mild imbalance, blindness, or personality changes—are possible.
• 🔁 Risk of recurrence exists if underlying conditions aren’t managed.

🏡 Ask A Vet App Home‑Monitoring Tools 📲🐶

• 📆 Schedule reminders for medications and vet checkups.
• 📊 Log neurological signs—circling, balance, appetite, elimination.
• 📷 Upload photos/videos of head tilt, eye position, gait.
• 🔔 Receive alerts for red flags like seizures or worsening imbalance.
• 📘 Access resources: stroke recovery exercises, and mobility support guides.

🔑 Key Takeaways 🧠✅

• Strokes are neurological emergencies—early veterinary care saves lives.
• Signs vary: weakness, circling, head tilt, seizures, blindness.
• Quick diagnosis (MRI, labs) and supportive care improve outcomes.
• Rehab is vital: aftercare includes therapy, assistive aids, lifestyle adjustments.
• Managing underlying conditions reduces future risk.
• Ask A Vet tools support recovery through proactive monitoring and communication.
