Fainting, also known as syncope, is a medical condition characterized by a temporary loss of consciousness. There are a number of possible causes for fainting in cats and dogs, some of which can be serious or potentially life-threatening if left untreated. If your pet faints, it is important to take them to your veterinarian as soon as possible so the cause of the condition can be diagnosed and treated.
Causes of Fainting
Most cases of fainting in pets are neurologic (related to the nervous system) or cardiac (related to the heart). Neurologic problems which can lead to fainting include abnormal brain activity and seizures. Cardiac issues associated with the condition include heart tumors, heart disease, abnormal heart rhythms, and heart blockages.
Fainting is most often seen in older pets, and certain breeds of dog including Boxers and German Shepherds appear to be more susceptible. Episodes of fainting often happen in certain situations such as when a pet is overexcited.
Symptoms of Fainting
Fainting is characterized by sudden collapse and loss of consciousness. During an episode of fainting your pet will be unresponsive to your voice or touch and their limbs will usually become stiff and rigid.
If your pet faints, remain calm and place your hands gently over their heart to see if you can detect an abnormal rhythm. If possible, it is also a good idea to take a video of the episode to show to your veterinarian. This information can be very useful for determining the underlying cause of your pet’s condition.
Diagnosis of Fainting
Your veterinarian will ask you a series of questions about the onset of your pet’s symptoms. They will then perform a thorough physical examination to check for abnormalities such as an irregular heartbeat. Blood tests, urinalysis, and other routine diagnostic tests will be performed to check for possible underlying causes of your pet’s condition.
If a heart problem is suspected, specialized tests such as an electrocardiogram (ECG) or echocardiography may be performed. In addition, your veterinarian may choose to carry out other diagnostic tests such as X-rays or ultrasounds to identify possible causes of fainting.
Treatment of Fainting
Treatment of fainting will focus on addressing the underlying cause of the condition. If your pet has heart problems, your veterinarian may prescribe medications or implant a pacemaker to regulate their heartbeat. In other cases, your pet may be withdrawn from medications that are contributing to spells of fainting. Please follow your veterinarian’s advice closely to help your pet recover fully.
Prevention of Fainting
Although fainting in dogs and cats is relatively rare, some pets are more susceptible than others. If your pet is prone to episodes of fainting take care to avoid too much stress and excitement. It is also vital to exercise your pet gently and schedule regular checkups with your veterinarian.
