Causes of fainting in dogs:

Canine fainting occurs in many different forms, and therefore there are many causes of fainting.

1. Cardiovascular system: Canine fainting may be related to problems with the heart or other organs of the body, and exercise-related fainting may be related to underlying heart problems. Heart problems include: abnormally low or high heart rate, damage to the heart muscle or valves, heartworm and heart tumors, etc. Heart disease can prevent sufficient blood oxygen from reaching the brain, causing fainting.

2. Vascular and vagal syncope: Sudden stimulation or pressure causes a short-term drop in blood pressure and stimulates the vagus nerve, leading to fainting.

3. Postural fainting: Dogs may faint due to coughing, defecating, urinating or swallowing.

4. Other reasons: hypoglycemia (hypoglycemia) and drugs (special drugs that affect blood pressure), etc.

Treatment for fainting in dogs:

1. Reduce the possibility of dizziness, minimize exercise or stimulation, and use stool softeners to reduce the stimulation of defecation.

2. Special drug therapy can be used to improve heart function and minimize vasovagal syncope. Any drugs that may cause syncope should be discontinued or avoided.
