Stroke Symptoms in Dogs
Stroke Symptoms in Dogs
A stroke, which is also referred to as a cerebrovascular accident, is a medical condition wherein distressing neurological symptoms occur due to disruption of blood supply to a part of the brain. This condition can also affect dogs. Though this condition is not commonly observed in dogs, it may occur as a result of an underlying disease.
Symptoms
A stroke can lead to a sudden deterioration in the dogs health. Here are some of the common symptoms that are indicative of a canine stroke:
- A stroke can cause tilting of the head on one side
- The dog may turn the wrong way on being called
- Loss of balance
- Sudden behavioral changes
- Lethargy
- Circling, house soiling and falling over very often
- Difficulty in walking
- Loss of control over bladder and bowel
- Vomiting
- Eyes may roll back and forth
- Confusion
- Loss of vision
Canine strokes are categorized into two types; ischemic and hemorrhagic. Ischemic stroke occurs when there is a lack of blood supply to the brain. This could be due to the formation of a blood clot or blockage that prevents blood from reaching the brain. Hypertension, diabetes, obesity, tumors or medical conditions associated with the heart, kidney and liver could increase the risk of ischemic stroke. On the other hand, a hemorrhagic stroke occurs when blood vessels in the brain rupture, thereby causing blood to leak. Traumatic injury, vasculitis, lung worm, brain tumor or abnormalities in the blood vessels in the brain could increase the risk for this kind of stroke. Such a leakage of blood could adversely affect the blood supply to the brain. Physical and neurological symptoms appear when blood enriched with nutrients and oxygen doesnt reach the brain. Bulldogs and pugs are more susceptible to such a condition. It is believed that their narrow respiratory pathways increases the risk of strokes. Hence, extra precautions should be taken by people who have such kinds of dogs as their pets. Very old and very young dogs are also susceptible to strokes.
Treatment
There is not much that can be done at home for the treatment of stroke in dogs. So, take your dog to a veterinarian without wasting any time. What can be done at home is proper feeding and anything that may improve your dogs quality of life. So, if you observe any of the aforementioned symptoms in your pet, it would be best to take your dog to the vet. Diagnostic tests such as the CT scan and MRI can certainly help in identifying the underlying cause. Though the damage caused by this condition could be irreversible, pet owners can at least make the necessary changes and take steps to prevent another stroke in future. Once the underlying medical condition has been identified, the veterinarian can suggest the best treatment option. The prognosis of stroke is definitely better in dogs than in humans. The affected dog may be able to recover motor functions within a few weeks. However, the time a dog could take to recover would vary depending on the intensity of the stroke. Once a dog has had a stroke, the dog owners must be ready to accept the behavioral changes and help the dog.
Prevention is always better than cure. So, do take your dog for regular checkups. Several diseases can increase the risk of canine stroke, so make sure that you give your dog good quality dog food. Exercise is also essential, so make sure that your dog stays active. This will help to lower the risk of obesity in dogs. If the dog receives proper treatment without any delay, it can recover completely within weeks and can live a healthy life.

Canine Stroke Prognosis
Canine Stroke Prognosis
The condition of stroke was considered as one of the rare medical occurrences in canines. However, with the advent and improvement of specialist tests, it has been found that this condition is fairly common in most types of dogs. So what is a stroke exactly. This disorder is defined as a condition wherein, part of the brain is devoid of adequate blood supply thus, causing a dearth in oxygen in the brain tissues and cells, eventually causing them to die. A stroke can occur in two forms; ischemic stroke and hemorrhagic stroke. The former type is known to be the most common types of strokes. It occurs when the brain arteries are narrowed and blocked (usually caused by a blood clot) thus keeping the brain from receiving enough blood to survive. And a less common occurrence is the other type, wherein, a blood vessel in the brain is caused to leak or rupture. Speaking of canine stroke prognosis, it basically refers to a prediction about how the condition would develop and what could be the most possible repercussion. And this prediction is done based on the experiences of hundreds of other dogs with the same condition.
What Influences the Prognosis of Canine Stroke?
Factors such as symptoms may give a clue about the current course of the condition, and the cause, about the severity. Also the complications of the problem may help to determine about how well the treatment can go, and the treatment itself can help in predicting the survival rate of the affected dog.
Symptoms
So how do you know if your pet has contracted this condition. When compared to human beings, canine stroke symptoms are different. Some of the most common symptoms which may indicate that the pet has had a stoke include:
- The animal may be seen tilting its head to a side, or walking in a leaning posture. According to experts, the side of the brain that has damaged is the side to which the dog may lean towards or tilt its head.
- The animal may become weak and appear so, as well
- Losing balance is one important symptom that must be watched out for
- The affected dog might turn to the wrong way when called
- Losing control of bladder and bowel is another classic symptom of a dog that has suffered a stroke. So you may find your pet voiding in unexpected or unwanted places
- Loss of appetite, lethargy, and behaving abnormally are the other symptoms
There could be many factors which can lead to the development of stroke in canines. The ones that vet commonly come across may include:
- Disease of the kidneys
- Diabetes
- Disease of the heart
- Parasitic infection
- Tumors
- Hypertension
- Hyperthyroidism or hypothyroidism
- Vasculitis
- Injuries and trauma
Complications
Depending upon the cause, the complications may vary. First, the symptoms which have been mentioned above may become permanent or stay for a temporary period, depending on how severe was the stroke. In addition to these, some dogs might become blind or develop paralysis. Also, the part of the brain that has been affected, and the underlying cause determine the severity of the condition.
Treatment
The treatment aims at correcting what has caused the stroke in your canine. Determining the specific cause or causes, not only help in the present situation, but also in preventing future strokes. For instance, if the cause is a parasitic infection, then worming the animal would be good enough for dealing with the condition. And if the cause is a chronic one, lets say, diabetes, then long-term treatment to control it may be put in place.
Prognosis
After studying the symptoms and knowing about what has caused the condition, a vet is able to predict the outcome of the condition. For instance, if the cause is a chronic one, then it is most unlikely that the animal would have a duly recovery. Dogs who receive prompt treatment, needless to say, have a brighter prognosis. Also, the same depends on how long has the animal survived after having diagnosed with the condition. Animals who have a longer survival, are known to have a better prognosis. In most cases, dogs are known to recover on their own within a few weeks. However, if the stroke has damaged a vital part of the brain, then the recovery and the prognosis may look bleak, depending on whether the condition can be treated properly.
What has to be understood is, prognosis is a mere prediction and must not be deemed to stand true always. It may happen that a dog whose prognosis is not a bright one, may have a full recovery, while one who was thought to be otherwise, did not show any positive results.
