How to treat acute and chronic renal failure in dogs?

Kidney failure is the most common kidney disease in dogs. When it is violated the excretory function of the kidneys. This process develops quickly and is accompanied by abrupt changes in water, acid-base and electrolyte balance.

The kidneys are less removed from the body of various substances and, as a result, they accumulate. At risk dogs older than 5 years.

Causes of Renal Failure

In most cases, renal failure occurs due to diseases affecting the blood vessels that filter the blood.

It can also be caused by prolonged exposure to kidney infections, birth defects in the form of a thickening of the internal structure of the kidney, inflammatory processes, and also cancerous tumors.

The cause of chronic renal failure in dogs are kidney diseases such as:

  • pyelonephritis,
  • glomerulonephritis,
  • renal dysplasia
  • heavy metal intoxication,
  • kidney amyloidosis


Symptoms of the disease often develop very slowly and may not appear even with complete damage to one kidney and damage to the second kidney by a third.

  • The disease manifests itself in the general depression of dogs.
  • The amount of urine changes dramatically. It can become much more due to the fact that the body can not hold fluid
  • There are frequent urination, which may be false
  • The animal constantly drinks, periodically the dog develops diarrhea and vomiting, it loses weight and appetite.
  • Edema may appear, pulse rate increases, mucous membranes turn pale
  • In some cases, you may experience stomatitis, tremors, muscle weakness.

Symptoms may not appear constantly and alone, so they are very important to consider and consult a veterinarian in time for the treatment to be effective.

The diagnosis is established on the basis of blood tests and ultrasound diagnostics.

Forms of the disease

Acute renal failure - a potentially reversible condition that is potentially treatable. Accurate and early diagnosis is very important for this. However, it is not easy to isolate this form at the moment, because it is possible that the disease did not appear now, but its chronic course that has not been previously identified has simply worsened.

Most often, veterinarians have to treat chronic renal failurewhich develops as a result of the irreversible and rapidly progressive loss of nephrons - the functional cells of the kidneys. This form is treated for a long time and does not always have an optimistic prognosis. It all depends on the degree of neglect of the disease. An incurable disease is a disease in which out of 800 thousand nephrons, 500 thousand are damaged.

Treatment of kidney failure in dogs

  1. In case of emergency, intensive methods are used: a liquid is administered intravenously through a dropper and a special diet is established.
  2. A dog is prescribed medications that improve blood composition, normalize the chemical balance of substances and, if necessary, relieve some symptoms, for example, stop vomiting.
  3. For problems with urination, the dog is provided with a free flow of urine using a catheter or even surgery.
  4. Also prescribed drugs that improve blood microcirculation in the tissues of the kidneys, diuretic drugs intravenously.

During the period of treatment, it is constantly necessary to monitor the vital functions of the animal's body, therefore, in acute periods, the animal is best left in the hospital. With the relief of the condition, the dog can be taken home, but to provide it with a benign mode: avoid stress, rest more, eat right.

Diet for renal failure

The diet for this disease should have a low content of phosphorus, proteins and calcium.

It is better to feed the pet often, but in small portions and to provide constant access to fresh water.

Do not give the dog:

  • vegetable oils,
  • fish fat,
  • egg yolks,
  • bones,
  • meat offal,
  • cheese

Fat meat, butter and egg whites at first give a little, gradually increasing to normal. The ideal source of protein in the diet of a sick dog is an unpeeled scar, especially its “book”. Even if you always feed your dog dry food, in the early stages of the disease, it is better to add fresh protein foods to your diet: raw meat, egg whites, tripe.

Approximately half of the diet should be carbohydrates: fresh ground vegetables (especially white potatoes), white rice, sticky varieties, semolina. Occasionally you can give oatmeal, brown rice, wheat, millet and other whole grains. To reduce the phosphorus in the body, you can add ground egg shells - half a teaspoon per pound of food.
