The dog faints. What to do?

Fainting is a sudden loss of consciousness that occurs in a dog due to insufficient blood supply of the brain vessels (hypoxia) in combination with a decrease in blood pressure.

This condition may be short-lived or long-lasting.

Causes of fainting dogs

There are quite a few reasons for fainting. So,

  • overwork (especially as a result of long transportation in a stuffy and cramped car),
  • hypothermia
  • stuffiness
  • more than a week of hunger
  • nervous stress or intoxication of the body

lead to vascular disorders. Cerebral vessels dramatically expand or contract and faint. Other causes of fainting in a dog can be neurogenic changes in the central nervous system or a sharp drop in blood sugar levels. In any case, the causes of fainting should be sought in the work of the vessels, heart or blood.

The most dangerous are syncope, resulting from a violation of cardiac activity. They can be quite long (up to half an hour), which often leads to the sudden death of the animal.


Nausea or vomiting can be a harbinger of fainting.

  • The dog can not stand
  • coordination is disturbed,
  • the animal weakens and lies down.
  • The mucous membranes turn pale,
  • breathing becomes shallow, barely noticeable,
  • limbs get cold

When a sudden fainting dog falls, she felt a weak pulse, the animal does not respond to commands and nickname.

First Aid Dog Fainting

The owner of the dog should be able to provide first aid for fainting, because it is needed very quickly. If the dog has fainted, you must immediately move it to fresh air, to a cool place or a shade. If this happened in winter, you can’t put it on bare ground, you need to spread something or find a wooden bench, platform or something like that.

  1. The animal must be freed from the collar, muzzle, harness, leash and put on its side.
  2. Putting the dog is necessary so that the head is below. This will ensure blood flow to the brain.
  3. To ensure such a position, you need to raise the back of the torso and under it roll up the rolled up clothes.
  4. Also urgently need to pull out the tongue and check whether there is no vomit in the airways. If they are found, then you need to clean the mouth with a finger.
  5. A cold, damp cloth can be put on the dog's head, and in winter, snow or ice wrapped in a scarf or towel.
  6. In the heat, you can just pour water over the head of the animal.
  7. After the dog regains consciousness, it should be given cold water to drink.
  8. If it is too weak and cannot drink on its own, then water should be poured over the cheek in small portions. Having moved the animal to a more convenient place, it is worth it to drink warm, sweetened water.

You can feed no earlier than one hour after the restoration of the normal state. To stimulate the work of the heart and respiration, if the animal has a heart disease, it can be given Corvalol, Cordiamine and other similar drugs. Even if the dog fainted once, it needs to be examined, since such a condition could be caused not only by environmental factors (transportation, stuffiness, etc.), but also by serious pathologies and heart disease.
