My dog is experiencing episodes of syncope, which is fainting in dogs.

My Dog Is Fainting - Syncope in Dogs

When a dog faints, they briefly lose both consciousness and their physical abilities, particularly their ability to move their muscles. Even while they only last a brief amount of time, they can be extremely unsettling, particularly if the dog repeatedly faints over time. We must consider the situation in order to comprehend why my dog is dizzy. Exercise and excitement are two major triggers for fainting, though there are other situations as well. AnimalWised provides information on the causes of canine fainting as well as available treatments. 

What causes canine syncope? 

We must be certain of its definition before we can discuss syncope in dogs. Syncope, also referred to as fainting, is a momentary loss of consciousness accompanied by a decline in muscle power. As a result, the dog will collapse and tip over. This loss is typically brought on by a reduction in brain oxygenation as a result of decreased blood flow. It could be accompanied by twitching of the muscles. 

Loss of consciousness, which is one of the primary symptoms used to diagnose syncope, is crucial. While fainting is a transitory condition, its durations might vary. A dog may faint so swiftly that they wouldn’t even have time to trip over themselves. Other times, a person may experience a loss of consciousness 

We must distinguish between fainting and other forms of consciousness loss. A dog, for instance, may lose consciousness if they experience toxic shock because their body is shutting down. This is extremely risky and might even be fatal. Dogs with epilepsy are another example; during a fit, the dog will appear to lose consciousness.

causes of canine syncope 

The following two categories can be used to differentiate the causes of syncope or fainting in dogs: 

Extracardiac origin:

This category covers neurological conditions like encephalitis, bleeding, and epilepsy. Metabolic causes include hypoglycemia, hypocalcemia, hypoadrenocorticism, or anemia; pulmonary causes include pulmonary hypertension; and situational factors include persistent coughing. 

The most typical cause of syncope in dogs, along with hypoglycemia, may be cardiac problems. The latter is brought on by a decline in blood sugar. It is concerning if the dog experiences arrhythmias since a sudden episode of fainting could be caused by cardiac arrest. We must be extremely cautious with our dog’s health and activity if they have been identified as having a heart murmur, congestive heart failure, or another type of congenital heart disease.

When thrilled, my dog passes out.

Dogs who experience high levels of excitement may experience syncope. A fight with another animal, making a lot of effort when walking, exercising excessively, or engaging in other activities that raise blood pressure are a few examples. If a dog has serious heart issues, even slight effort, like straining to urinate, might make them pass out. 

The cause is that tachycardia is brought on by increased physical exertion. This causes syncope, stimulates the vagal system, and slows down heart rate. In canines, this is referred to as vasovagal syncope. 

Elderly dogs are much more prone to fainting. The body begins to deteriorate as a result of an extended existence. Minor actions become more difficult to do. Blood pressure may drop and the dog may become more susceptible to fainting if the heart muscles have also deteriorated. 

The fact that some dogs are more likely to faint than others should be noticed. Breeds of brachycephalic dogs like Pugs and Boxers are among them. Since their morphology confines airways, this is frequently caused by coughing. Then, the thorax’s pressure rises, putting strain on the heart’s muscles. Blood flow is reduced as a result, which causes syncope. 

In comparison to larger dog breeds, smaller dog breeds are also more likely to faint. When agitated, dogs like Chihuahuas and Yorkshire terriers can have hypoglycemia, which frequently causes them to faint. This is especially true for these breeds’ young puppies. These breeds are also more vulnerable to tracheal collapse. This is a stoppage of airflow through the trachea, which can occasionally cause syncope. 

Canine syncope symptoms 

The dog may exhibit symptoms of dizziness prior to syncope. Our dog is more prone to faint if they exhibit any of the following symptoms: 

Sudden and temporary loss of consciousness 

Loss of posture 

Lies on its side 

Legs are stiff 

Emit vocalizations 

Urinates on themselves 

The dog usually recovers quickly from syncope, which typically lasts for approximately a minute. Because of this, it is typical to see dogs faint for a few seconds at a time. If our dog has collapsed, we must call our veterinarian and provide them with all the information necessary for

them to make a diagnosis. As previously mentioned, there are other potential causes of a dog losing consciousness, some of which are potentially fatal. 

We must examine the dog’s behavior both before and after the incident. If our dog is being treated for a sickness or has a condition, we must also let the vet know. The examination of the cardiovascular, pulmonary, and nervous systems will take up most of the time. Dogs are subjected to blood and urine tests to look for endocrine or metabolic causes of syncope.What should I do if my dog faints? 

A syncope has a variety of reasons, as we have already mentioned, and it is not an illness in and of itself. We should take them to the vet to find out the underlying problem, even if they have only had one episode. Exercise, tension, excitement, fear, pain, and other situational triggers should all be avoided to the greatest extent feasible if they are the cause. The vet will need to decide on the best course of action and medication in cases involving disease. 

Tests such an electrocardiogram, blood pressure measurement, ultrasound, etc. will be required in order to identify the reason and cure fainting in dogs. The canine may need to take blood pressure medicine, and the signs may need to be maintained for the rest of their lives.
