Dog fainting may be the result of disorders like epilepsy, or of conditions like narcolepsy or cataplexy. There are dozens of diseases and conditions that can cause dog fainting. Some of the most common include: 1  Hepatic encephalopathy, a disturbance in brain function caused by liver disease or deformity of the liver. 2  Hypocalcemia, or low blood calcium levels. 3  Hypoglycemia, or low blood sugar.
Low blood oxygen (hypoxia) will also cause your dog or cat to breath more rapidly. The two most common causes of low oxygen are heart failure and anemia. The most common causes of heart failure are heart valve failure in older pets and heartworms (usually in younger dogs).
