Advanced Kidney Disease in Dogs

Kidney disease is a serious condition that affects many dogs. Chronic kidney disease occurs over many years as dogs age and may lead to acute kidney failure.

  1. Identification

    • The kidneys are responsible for removing waste from the dog's body and also maintaining healthy levels of water and salt in the body. If the function of the kidneys decline, the dog's body becomes less efficient at removing these waste products. In an effort to keep the proper balance in the body, the kidneys begin to produce more urine and the dog will begin to urinate more frequently. This is known as renal (kidney) insufficiency or in advanced stages renal (kidney) failure.

    Causes

    • The most common cause of kidney disease in dogs is aging. Other conditions such as diabetes or cancer may also cause the kidneys to fail.

    Early Warning Signs

    • The early warning signs of kidney disease in dogs are excessive thirst, excessive urination, fatigue and decreased appetite.

    Advanced Symptoms

    • Symptoms of advanced kidney disease may include nausea, vomiting and diarrhea. Dehydration and weight loss may also occur. Dogs that have advanced kidney disease will look unhealthy.

    Diagnostic Tests

    • To determine if kidney disease is present in dogs, the veterinarian may run blood urea nitrogen and creatinine tests. The levels of nitrogen and creatinine in the dog's body, will help the veterinarian to determine the health of the kidneys. The higher the levels, the more advanced the kidney disease is.
