Yes. Dogs and cats can have strokes, but sudden neurologic signs do not confirm one. Collapse, head tilt, circling, stumbling, blindness, or disorientation can also have other causes. If these signs appear, call your veterinarian or an emergency clinic promptly, describe what changed and when, and call ahead before you travel.
What a stroke looks like in a dog or cat
A stroke is a sudden interruption of blood supply to part of the brain. Its signs can begin abruptly and vary according to the affected brain region and the degree and duration of reduced blood and oxygen supply. Possible signs include:
- Collapse or sudden difficulty standing
- Head tilt, circling, or stumbling
- Blindness or disorientation
- Rapidly moving pupils
- An abrupt change in behavior
These signs are reasons for prompt veterinary assessment, not a way to diagnose a stroke at home. VCA describes strokes as rare in dogs and cats but does not provide a prevalence figure. Its cat resource reports cases in cats aged 2 to 21 and says no breed predisposition has been identified; its dog resource says Cavalier King Charles Spaniels and Greyhounds seem more likely to be affected. Those details are context, not a means of determining whether an individual pet has had a stroke. VCA: Stroke in Dogs; VCA: Stroke in Cats
What to do if signs start suddenly
- Call your veterinarian or an emergency clinic now. Explain which signs you see and when they began. Follow the clinic’s instructions for immediate care.
- Call ahead before traveling. This gives the team a chance to prepare and advise you about safe transport. The MSD Veterinary Manual’s emergency guidance advises calling the veterinarian, following instructions, and calling ahead.
- Do not try to treat a suspected stroke with medication at home. In particular, do not give human clot-busting drugs or other medicines unless a veterinarian specifically directs you. VCA says the use of thrombolytic drugs used in human medicine has not been established in animals.
How a veterinarian checks for a stroke
Several conditions can cause signs that resemble a stroke, so a veterinarian may need to investigate other explanations. Depending on the animal and the case, the workup may include blood tests, imaging, clotting analysis, investigation for infectious disease, or cerebrospinal fluid analysis. VCA identifies MRI as the ideal diagnostic test for a stroke and its consequences in the brain. VCA: Stroke in Dogs; VCA: Stroke in Cats

Causes, treatment, and recovery
A clot—a thrombus or embolus—can block an artery in the brain. Bleeding in the brain can also cause a stroke; VCA notes trauma and low platelet counts among possible contexts. In many cases, the cause is unknown. Treatment is complex and depends on the individual animal and any underlying cause the veterinarian identifies. There is no single home treatment or guaranteed outcome. Some animals regain much of their motor function, but prognosis varies with factors including the underlying disease and the brain region affected. VCA: Stroke in Dogs; VCA: Stroke in Cats

Sudden hind-limb weakness or paralysis in a cat—especially when the legs are painful and cold, the foot pads look pale or purple, or pulses in the hind limbs are weak or absent—may indicate feline arterial thromboembolism. This is a clot problem affecting circulation to the limbs, not a brain stroke, and it also needs emergency veterinary attention. VCA: Aortic Thromboembolism in Cats
