What is fainting?
Fainting, also known as syncope, is a sudden and brief loss of consciousness caused by a reduced blood supply to the brain. Fainting can occur in humans and animals and is usually a sign of cardiovascular disease.
What are the causes of fainting in dogs?
There are many possible causes of fainting in dogs, ranging from harmless to life-threatening. Some of the most common are:
- Heart problems: Cardiac arrhythmias, heart valve defects, myocarditis, heart failure or heart attacks can cause the heart to not pump enough blood to the body and blood pressure to drop.
- Breathing problems: Airway constriction, pneumonia, asthma or pulmonary edema can affect the oxygen supply to the blood and lead to hypoxia (lack of oxygen).
- Nervous system problems: Epilepsy, stroke, brain tumor or meningitis can disrupt the function of the brain and lead to syncope.
- Metabolic problems: Diabetes, hypothyroidism, liver or kidney disease can upset blood sugar or electrolyte balance and lead to fainting.
- Other factors: Stress, anxiety, pain, heat, dehydration or medication can also trigger fainting.
