A dog suffering from cerebral thrombosis will have symptoms of unsteady walking, lethargy, listlessness, and uncoordinated limbs. Once the dog is found to be in an abnormal state, it needs to be checked and treated at the hospital as soon as possible. Cerebral thrombosis in dogs is a relatively serious disease that causes great damage to the brain. Severe cases can cause shock or death in dogs. If discovered early, active treatment can restore the condition.
