10 Causes of Kidney Failure in Dogs, The symptoms, and Treatment

Kidney failure in dogs is undoubtedly one of the terrifying things occurs to your pet. Like in human kidney, the dog kidney play the same role in the health such as expel the toxin from the body through the urination processes. A healthy kidney can make a large number of toxins are secreted in a little amount of water, thus making the urine are entirely concentrated. On the other hand, the kidney failure makes the body need a significant amount of water to expel the same amount of water.



Kidney failure in dogs usually occurs in the older dogs; it is affecting almost 10% canines in their lifetime. But some factors may appear in the early stage of life because of the genetic trait.  There is a lot of causes and have different consequences and also affecting the different group of ages.

10 Causes Kidney Failure In Dogs: Symptoms And Treatments

1. Glomerular damage

Canine kidney disease commonly caused by the damage of glomerulus that being responsible to the kidney filter mechanisms. There will be no symptoms of the early stages of kidney failure in dogs, but since the kidney failure that caused by the glomerular disease are originated from an infection such as cancer or lime disease. Over time the inflammation and the infection will get worse and damage the kidney tissue around the infection sites, creating a chronic illness.  That will make your dog feeling sick.

2. Pyelonephritis (Infection of Kidney Tissue)

The infection of Kidney that caused by fungal or bacteria are the most favorable outcome when it comes to the kidney failure, so maybe your veterinarian will look out for it first. Inflammation damaging by bacteria have to stop, and it is the goals in the treatment of Pyelonephritis, to kill the bacteria. When the bacteria are gone, it will assist the recovery of acute renal injury and should limit the development any chronic kidney disease.  To know the most suitable antibiotic or antifungal, you have to verify and identify the bacteria, and it can be by using the urine culture.

3. Nephrolithiasis or Kidney stones

Genetic, diseases and bacterial infection may be the cause that alters blood and urine characteristics, thus produce kidney stones in the renal tissue. This damage usually doesn't make your dogs feeling too much pain and sicks, but it is different if the nephron (kidney) and liths (stones) are blockages the urinal production as such as urinal flow in the renal ducts. It also change if the kidney stones contribute to the infection and inflammation, thus can make other damage to kidney tissue.

4. Ureteral obstruction with Hydronephrosis

Kidney stones can lodge in the ureter ( a long narrow tube that connects urinary bladder and kidney), causing the complete or partial blockage. It is the primary concern to the kidney. However, the fragment of kidney stones also causing pain when it transferred within the ureter. The obstruction makes the urine cannot exit, and it backs up to the kidney, which makes the kidney to swell. It can become kidney enlarge (hydronephrosis) and damage, and it makes things more severe if there is also occurs ureter obstruct. 

5. Tubulointerstitial disease (Kidney Tubules damage)

Chronic kidney disease may be caused by damage and inflammation to the supporting tissue and kidney tubules. There is no specific treatment because not many identified a cause for that matter. This type of kidney failure in dogs can be confirmed only by biopsies to examine the kidney tissue in the microscope.

6. Leptospirosis (Infection of bacteria)

Leptospires are the cause of dogs renal failure and other organ challenges in dogs and another organism including people around the world. The effect of Leptospirosis is normally causing an acute renal injury. Occasionally, this bacterial infection may cause chronic kidney failure. The early recognition of symptoms of kidney disease in dogs makes the better outcome for the treatment.

7. Toxins

You know dogs like to eat stuff, lick stuff bathe in stuff or roll in stuff, it may put the dogs in the real risks. There are a lot of items that can damage the kidney, like ordinary food such as OTC medication like aspirin and other nonsteroidal, jerky treat product, antifreeze and even raisins and grapes. To reduce the risk of dogs renal failure, you may want to limit its free-roaming behavior and considering every medication you want to give without the veterinarian discussion first.

8. Cancer

Kidney cancer, fortunately, is not common in dogs. But, the problem is kidney cancer treatment in dogs also limited. The treatment for solitary tumor may be can do with the surgery, if cancer was not spreading to the other sites. If it is already spread, as usually occurs in the lymphosarcoma the biopsies may be needed to examine the kidney sample and to choose the suitable methods for the treatment.

9. Amyloidosis (Protein issue)

The dog that has amyloidosis may lose function of the certain parts of the body, including renal, thus make the kidney failure in dogs. It may be genetically programmed on the certain dog's breeds. Amyloid makes the protein deposits replace the healthy tissue and cannot be cleared. The prognosis is not good because the kidney tissue that loses its function cannot be returned.

10. Hereditary

Genetic links to some traits that the dogs have. In some unfortunate cases, there are some dogs that fail to have a healthy kidney and have the kidney with the grape-like and fluid-filled cysts. This heredity may appear in the younger dogs, or in the adult's dogs. For the best solution, you need to bring your dogs to the veterinarian at the first place. Make sure they are treated by the expert one to prevent them suffering from any other severe diseases.

Not every kidney failure in dogs caused are known or understood, nor every case of the dog's renal failure can be prevented or controlled. But maybe you can start to give the pup’s the balanced, species-appropriate diet than give it a commercial one. Also, you may be cautious of the symptoms of kidney disease in dogs by noting the behavior of the pets such as appetite, behavior, thirst and energy level.
