Obvious symptoms of Syncope

You should know that fainting is not a disease in itself. Rather, it is a reversible conjunctural condition or syndrome, which can hint at the existence of a secondary pathology that requires therapy.

It is generally involved with cardiomyopathy or a condition of the nervous system, so an early diagnosis is the best measure to preserve the health of our dog.

As a general rule, it usually occurs with the following symptoms:

  • Lack of knowledge or response to our claims.
  • Rigid extremities.
  • Lost look.
  • Urination (urine)
  • Muscle spasms that can be mistaken for a epilepsy episode.
  • Paleness of mucous membranes, whitish gums.

It is usually more frequent in older dogs and, in particular, in the breeds of Cocker Spaniel, Miniature Schnauzer, Boxer, German shepherd, Pug and Dachshund.

Why do these fainting spells occur?

There are many factors that can cause our dog to end up fainting, lose consciousness and even appear to have an epileptic fit.

The main triggers at general levels are:

  • Slow heart rate (bradycardia) or fast heart rate (tachycardia).
  • A cardiac tumor (not necessarily malignant).
  • Hypothermic ventilation.
  • Stress (one of the main causes)
  • Exposure to certain medications that lead to blood clots or thickening.
  • Hypoglycemia.
  • Calcium or sodium deficiency in the blood.

The so-called situational syncope deserves special attention. We refer to loss of consciousness caused by cough, difficulty swallowing, urinating, or defecating, as well as overstimulation of the carioid sinus, for example, by pulling the strap abruptly. In all of them the prognosis is usually positive and immediate recovery.

What should I do if my dog ​​suffers from syncope?

In a situation of this type, you should go to your vet as soon as possible. As it is an indicative medical condition, the specialist must determine the exact cause to prevent its progression and establish the corresponding treatment.

Remember to inform them about any past illness or about the medicine you are taking, if so.

It will be necessary to carry out a detailed medical examination with complete blood count, urinalysis and biochemical profile.. It may happen that the parameters are normal. However, if the cause is hypoglycemia it will be easily detectable, as well as low levels of calcium or sodium in the blood.

If cardiomyopathy is suspected to be the true cause of fainting, additional tests such as an electrocardiogram or echocardiogram will be performed. The same can be said of computed tomography or analysis of the cerebrospinal fluid, if it is estimated that the genesis lies in brain dysfunction.
