Canine stroke is very rare among dogs; however it does occur when the blood flow to the brain is disrupted due to a blocked artery or a possible hemorrhage. There are two main types of stroke in dogs.
Ischemic stroke, just like humans, is a condition caused due to the lack of blood flow to the brain. This happens because there is a block in the artery. This stroke is directly linked to some of the below mentioned conditions:
- Kidney diseases
- Heart diseases
- Cushing diseases
- Malfunctioning thyroid glands
Hemorrhagic strokes are also common in dogs. It is caused due to the improper blood flow in the brain. These episodes may be caused due to kidney diseases, heart diseases, and/or thyroid diseases. They can also be caused due to high blood pressure. A particular type of lung worm called angiostrongylosis can cause hemorrhagic strokes in dogs. Rodent poisons may also cause strokes if the dog swallows it. Arterial inflammation if existent in the dog may cause it. Immune related thrombocytopenia and a brain tumor are some of the causes. A typical blood vessel that develops in the brain and a head trauma can cause this type of stroke in dogs.
Symptoms of canine stroke are very similar to humans. However, the diagnosis could be more complicated in canines. If you notice your dog to be less attentive, the head is tilted and see loss of bowel or bladder control, then contact the vet immediately. It is quite possible that your dog may be suffering from a stroke.
