This material can become lodged in a blood vessel, preventing blood and oxygen flow, which causes the tissue around the blood vessel to die. Most strokes involve blood clots, but some are caused by tumor cells, bacteria, and parasites. Dogs will exhibit different neurological signs depending on damage severity and the part of the brain affected. What is a stroke?Ī stroke occurs when a blood vessel becomes blocked or narrows so blood and oxygen no longer are carried to the brain, causing brain cells to die. Unfortunately, pets usually experience strokes on a grander scale than people and require immediate veterinary attention. Pet owners often don’t notice signs of a mild stroke in their companions since animals can’t tell you when they feel dizzy, lose sight in one eye, or have memory problems. Cats and dogs can have strokes, but they seem to occur less frequently in pets than in people.
