Dogs can suffer from strokes, but the symptoms differ from what we see in people. Find out the possible symptoms and the current treatment options available with this guide.
Can dogs have strokes?
Yes, dogs can have strokes, although they are thought to be a lot less common than in humans. While in people, symptoms include paralysis on one side of the body, and facial drooping, these symptoms are extremely rare in pets. In fact, many of the symptoms of stroke in dogs are relatively non-specific and can be indications of a variety of other medical conditions. This means that diagnosis can be challenging, and in many cases, we might never know the underlying cause.

What is a stroke?
A stroke is the result of reduced blood flow to the brain which deprives the brain cells of sufficient oxygen, resulting in cell death or injury. Usually, a stroke will occur very suddenly, and the damage caused can range from mild to severe, which may depend on which part of the brain is affected. Some mild strokes can even go undetected.
Causes of strokes in dogs
To understand the different causes of strokes in dogs, it is helpful to learn about the two broad categories. Firstly, there are ischemic strokes which can be caused by blood clots, tumours, bacteria or parasites. In the event of an ischemic stroke, there is a blockage in a blood vessel, disrupting blood and oxygen supply to the brain. The other type of stroke is referred to as a haemorrhagic stroke, which is where blood vessels rupture and leak blood into the brain. This type can be caused by trauma, and some diseases or clotting disorders.
All dog breeds can suffer from a stroke, but there are certain breeds which are more predisposed to the underlying causes, including King Charles Cavalier Spaniels and Greyhounds.
