Pulmonary edema in the dog symptoms

Lung edema is a critical condition of the body. Edema can develop as an independent disease or be a consequence of other serious illnesses. With this pathology, the capillaries are filled with blood, and formation of exudate is observed, which subsequently enters the intermediate lung tissue and the alveoli. Lung edema leads to violations of breathing and gas exchange. This pathology may resemble asphyxia.

Most often, the edema and sports dogs suffer from the edema of the lungs. Such statistics are explained by the fact that it is these breeds of dogs who suffer severe physical stresses.

Causes of pulmonary edema

Pulmonary edema is a serious pathology that can be caused by a number of serious diseases and disorders in the body, among which:

  • Diseases and heart defects (for example, endocarditis andcramping), intravenous infusion. The above diseases affect the hydrostatic pressure in the vessels of the animal. It rises rapidly and leads to a violation of the permeability of the capillary and the release of blood into the lung tissue.
  • Hypoproteinemia is a disease that triggersmechanism of reduction of oncotic pressure. This creates an imbalance between the oncotic pressure of the intercellular fluid and a similar blood pressure. The organism tries to eliminate this difference, so the liquid leaves the vessel in the interstitium.
  • Inflammation of the lungs, intoxication of the body. These diseases lead to a sharp increase in the permeability of capillary membranes and alveoli. This, in turn, provokes damage to the very protein structure of the membranes. The fluid (as in the case of hypoproteinemia) thus leaves in the interstices.
  • Renal failure.
  • Head injury.
  • Overheating of the body.
  • Races for long distances.
  • Inhalation of excessively hot air.
  • Electric shock.
  • Poisoning into the body (eg, snake).

Symptoms accompanying pulmonary edema in dogs

Pulmonary edema is a condition that iscritical and requires immediate professional intervention. About pulmonary edema is also evidenced by a number of other symptoms, including rapid pulse and breathing, severe shortness of breath, blueing of the mucous in the dog's mouth, fussiness and chaotic behavior, and tachycardia. Often when swelling of the lungs from the mouth of the pet, a substance that looks like foam, saliva fluid or vomiting is released. These clinical signs may manifest themselves in different ways, depending on the cause of edema. They usually provoke acute respiratory failure, which can pose a serious danger to the life of the dog.

Diagnosis of pulmonary edema in dogs

The diagnosis of such a phenomenon is based ona detailed analysis of all the symptoms, listening to the organ, as well as the data of X-ray research. In this case, wet rales should be seen in the dog's chest. A general blood test, in turn, indicates an increased activity of liver enzymes, leukocytosis, and also hyperaemia. Also, the veterinarian often conducts an echocardiographic study that allows you to drop all possible cardiac disorders that are quite capable of leading to pulmonary edema.

As for the chest X-rayanimal, with suspected pulmonary edema, this procedure is carried out in two perpendicular projections. Pathology is detected if the picture shows a marked decrease in the transparency of lung tissue, as well as indistinctness and increase in their roots. Such violations can be traced in all parts of the organ, or be focal, which, however, is observed rarely.

The task of veterinarians, as a rule, is complicated by the fact,that pulmonary edema should be separated from various pathologies that have a similar symptomatology. Among such critical conditions of the body is the collapse of the trachea, various neoplasms, laryngeal paralysis, and airway obstruction.

Treatment of pulmonary edema in dogs

The effective treatment of edema depends on bothveterinarian, and the owner of the animal. The dog should be given complete rest, as much as possible to limit physical activity, and also whenever possible to protect it from any stress. With pulmonary edema, oxygen inhalation and medication are also administered. The latter, in turn, involves the use of glucocorticoids, vasodilators, bronchodilators and diuretics. If the sick dog is very nervous, the veterinarian prescribes sedatives, for example, acepromazine. Bloodletting can also be used. Intravenous dog is given calcium chloride and glucose solution. To maintain the normal operation of the heart, Cordiamin or caffeine is used. In some cases diuretics are prescribed.

If there is a non-cardiogenic edema, first of all, measures aimed at treating the underlying disease are applied.

Pulmonary edema is a critical condition, andthen the pet is most often transferred to a hospital. This allows you to constantly monitor the animal, as well as conduct surveys and take resuscitative measures, if necessary.

Special rules for the prevention of pulmonary edema simplydoes not exist. Reduce the risk of pathology will allow the correct maintenance of the dog, moderate physical activity, as well as avoiding overheating of the animal. If the main symptom of edema is shortness of breath, then you should immediately contact a veterinary clinic.
