Chronic renal failure refers to a condition characterized by the inability of the kidneys to function adequately. Chronic renal failure is a slow, progressive disease, usually going unnoticed until a large portion of the kidneys are damaged. When approximately 75 percent of kidney tissue is damaged, symptoms of chronic renal failure appear.

Normal Kidney

The kidneys are essential for survival. They are responsible for regulating body fluid composition, helping in red blood cell production, filtering the blood, and eliminating waste products.

Kidney—Chronic Renal (Kidney) Failure

Symptoms of chronic renal failure are insidious and slow to appear. The first noticeable symptoms are an increase in thirst and an increase in urine production. Vomiting, diarrhea, decreased appetite, and depression are also very common. Animals are often weak, due to a decrease in red blood cell production.

Chronic renal failure is a progressive, irreversible condition. Presently, there is no treatment that reverses the damage done to the kidneys. Instead, treatment is aimed at controlling clinical symptoms and preventing further damage from occurring.

Management of chronic renal failure involves cooperation between the client, the veterinarian, and the veterinary staff. Regular veterinary visits, which include blood testing, are necessary to monitor the pet’s medical condition.
