What Causes Kidney Failure in Dogs?

Kidney disease is a common problem of older dogs, affecting an estimated 10% of canines in their lifetimes1. There are a number of causes that may affect different age groups and have different consequences, ultimately though, chronic kidney disease (occurs over time) or acute kidney injury (occurs suddenly) will always have the same resultone sick pup. The signs of illness in your dog reflect the failure of the kidneys to do their many jobs well enough.

A bacterial urine culture and susceptibility can verify the infection and identify which antibiotic might work the best.3. They are probably painful during their transit, but the bigger concern is the consequence to the kidney if they become lodged there, causing partial or complete blockage.

Quick recognition of this highly treatable disease should lead to a better outcome and protect your dogs friends and family (YOU!) Ordinary table foods like grapes and raisins; certain commercial jerky treat products; common OTC medications like aspirin or other nonsteroidals (NSAIDs); or prescribed medications can all cause kidney disease. To reduce your buddys risk of kidney injury, consider limiting his free-roaming behaviors and refrain from giving him any medications without discussing it first with your veterinarian.

Microscopic analysis of a biopsy or small needle sample is needed for the correct diagnosis of cancer and appropriate treatment plans. Amyloid deposits cannot be cleared away, and the functional kidney tissue that is lost cannot be replaced, so the prognosis is not good. HereditaryThere are genetic links to various kinds of kidney disease for many purebred dogs.

Other dogs with congenital problems of the glomerulus or with a predisposition to amyloidosis might only show signs or symptoms of kidney disease when theyre adults.

What foods cause kidney failure in dogs?

Ordinary table foods like grapes and raisins ; certain commercial jerky treat products; common OTC medications like aspirin or other nonsteroidals (NSAIDs); or prescribed medications can all cause kidney disease. Venoms, pesticides and heavy metals are less common toxins.

What would cause sudden kidney failure in a dog?

Severe infections in the kidney from bacteria can cause sudden kidney failure. Although kidney infections can occur spontaneously, usually there is a preexisting condition that reduces an animal’s ability to fight infection easily – such as kidney stones, partial urine blockage or chronic kidney disease.

Can a dog recover from kidney failure?

Sadly, many dogs with acute renal failure will not survive more than several days. 2 However, if caught early enough and treated aggressively, some dogs can fully recover. Treatment generally involves intravenous fluid therapy and supportive medications.

What are the early signs of kidney failure in dogs?

Significant weight loss..Vomiting..Pale gums..Drunken behavior or uncoordinated movement such as stumbling..Breath that smells like chemicals..Significant decrease in appetite..Increase or decrease in water consumption..Increase or decrease in volume of urine.

The kidneys have many functions. They principally act to remove waste products from the blood stream, regulate the levels of certain essential minerals such potassium and sodium, conserve water, and produce urine.

After approximately 2/3 of the kidney tissue is destroyed, there is a rapid rise in waste products in the bloodstream and an apparent sudden onset of severe disease. The clinical signs of more advanced kidney failure include loss of appetite, depression, vomiting, diarrhea, and very bad breath.

If a major stress such as illness or surgery occurs, the kidneys may fail, sending the blood test values up quickly. This flushing process is called diuresis and helps mildly damaged kidney cells to function again by removing the toxic metabolites and creating a healthier environment for healing. “If enough functional kidney cells remain, they may be able to adequately meet the body’s needs for filtration and waste removal.”

Other important aspects of initial treatment include proper nutrition and medication to control vomiting and diarrhea if present. The ideal diet for a dog in the advanced stages of kidney failure is lower in protein, low in phosphorus, and is not acidified. This type of diet helps reduce the amount of protein wastes or metabolic toxins that may make your pet feel sick and lethargic.

Certain drugs will bind excess phosphates in the intestinal tract so they are not absorbed into the bloodstream, resulting in lower blood levels of phosphorus. This serves to prevent dehydration, helps continually flush toxins from the kidneys and provides additional levels of electrolytes. Therefore, many dogs in kidney failure will be unable to produce erythropoietin and have anemia or a low red blood cell count.

Synthetic erythropoietin may stimulate the bone marrow to make red blood cells and correct the anemia in most dogs. Treatment and follow-up care is relatively easy and inexpensive and extending the length and quality of life for their faithful companion represents the ultimate reward for many clients.

Renal failure (also referred to as kidney failure) can be caused by many conditions that negatively affect the health and functioning of the kidneys and its related organs.

This type of infection can cause the kidneys to become inflamed and renal cells to be destroyed. The elevation of blood waste product and abnormalities in urine, including the presence of protein, can indicate the severity of chronic kidney disease.

Its best if some treatments are started when the pet is at a specific stage of chronic kidney disease. Median survival time for Stage 4 kidney disease ranges from 14 to 80 days, according to IRIS. Signs of chronic disease in dogs can vary from subtle and slowly progressive to severe.

Drinking too much and producing large volumes of urine General depression associated with elevation of waste products in blood Overall weakness caused by low potassium in the blood Increased volume of urine in the bladder By the time a dog experiences renal failure, the disease has advanced and you may notice such signs as: Blood in urine Lethargy Pale gums Ulcers in the mouth Intestinal seizures Significant weight loss Drunken behavior or uncoordinated movement such as stumbling Significant decrease in appetite Breath that smells like chemicals Vomiting

Factors to be considered may include the type of renal failure your dog may be experiencing, the extend of loss of function in the kidneys, progression of the condition and its underlying causes. Your veterinarian will perform diagnostic blood and urine tests to detect the presence of any abnormalities. While a diagnosis of renal disease or failure can usually be made based on physical examination, in addition to the blood and urine tests.

Aggressive treatments may include hospitalization for fluid therapy, dialysis or a kidney transplant. As your dog progresses through stages of renal disease, survival time is likely to grow shorter. Your dogs initial response to conservative therapy may be relatively slow it may take weeks or months to see progress.

The kidneys perform many vital functions, including the removal of various toxins from the body. These toxins are waste products from normal cell functions.

Antifreeze (radiator fluid, ethylene glycol) Lily plants (cats only) Raisins and grapes Certain drugs, including pain pills such as aspirin or ibuprofen (Advil or Motrin) Heatstroke or other disorders causing massive damage to body tissues, such as bee stings or snakebites, can also lead to kidney failure.

Stomach or intestinal ulcers may develop which will result in either a black or tarry stool or vomiting of digested blood (which looks like coffee grounds). Blood and urine tests are used to diagnose acute kidney failure and to assess the severity of disease. These fluids are used to restore good hydration and to flush out the substances that the kidneys should be removing from the bloodstream.

Temporary Feeding Tube: because kidney failure drains the bodys resources, and pets with kidney failure frequently refuse to eat, a temporary feeding tube may be recommended. Careful Monitoring: the clinical condition of dogs and cats with acute kidney failure can change rapidly. The increased potassium level slows the heartbeat and can cause the heart to stop.

This may manifest itself as increased body weight, belly bloating, swollen legs, or shortness of breath if fluid builds up in the lungs. Initially, this procedure requires a doctor or nurse 24 hours a day to keep flushing the fluid in and out. Despite all the advances in the treatment of acute kidney failure, it remains a serious and often fatal disease.

About 60% of dogs and cats with this disease either die or are humanely euthanized because of failure to respond to supportive care. In those patients, 50% may recover with dialysis, depending on the underlying cause of kidney failure.

What do my dog’s kidneys do?

The kidneys have many functions. They principally act to remove waste products from the blood stream, regulate the levels of certain essential minerals such potassium and sodium, conserve water, and produce urine.

Acute Renal Failure: Symptoms, Diagnosis and Treatment

The kidneys perform many vital functions, including the removal of various toxins from the body. These toxins are waste products from normal cell functions.When kidneys fail, they can no longer remove these toxins. “Acute” renal (kidney) failure means that the problem developed relatively quickly.

Symptoms

Many things can cause acute kidney failure. Certain poisons are well known for their ability to damage the kidney. These poisons include:Severe infections in the kidney from bacteria can cause sudden kidney failure. Although kidney infections can occur spontaneously, usually there is a preexisting condition that reduces an animal’s ability to fight infection easily – such as kidney stones, partial urine blockage or chronic kidney disease.Leptospirosis is a bacterial infection (Anything that decreases blood flow through the kidney can cause kidney failure. This includes dehydration from any cause (such as severe vomiting and diarrhea). Heatstroke or other disorders causing massive damage to body tissues, such as bee stings or snakebites, can also lead to kidney failure.

Diagnosis

Blood and urine tests are used to diagnose acute kidney failure and to assess the severity of disease. Other tests, such as radiographs (X-rays), ultrasound and special blood tests are usually necessary to help determine what might have caused the kidney failure. Sometimes a biopsy of the kidney is recommended.However, the cause of kidney failure is not always easily discovered and may never be determined.

Advanced Therapies

Potassium is an electrolyte normally found in the blood in low levels. With acute kidney failure, potassium levels may increase to dangerous levels, unlike in chronic kidney failure when levels tend to decrease. The increased potassium level slows the heartbeat and can cause the heart to stop. Alternatively, very high blood pressure could also develop because of the kidney failure, so blood pressure medication is frequently needed. High blood pressure can cause blood vessels in the eye or brain to burst.
Fluid retention may occur if urine production is less than IV fluid input. This may manifest itself as increased body weight, belly bloating, swollen legs, or shortness of breath if fluid builds up in the lungs.
