Dog Kidney Disease
Definition of Kidney Disease
Kidney disease, also called renal disease, is fairly common in dogs, especially as they age. The kidneys are responsible for filtering waste products from the blood. They also produce a number of important hormones and help regulate the body’s concentrations of hydrogen, sodium, calcium, potassium, phosphate and other key substances. One of the most troubling aspects of kidney disease is that affected dogs don’t show signs until about 75% of their kidneys are irreversibly damaged. Their symptoms appear suddenly, even when the disease has been progressing for some time. Signs stem from the kidneys’ fading ability to flush toxins out of circulation and are extremely varied. They include weakness, lethargy, increased water consumption and urine output, weight loss, abdominal distension and pain, oral ulcers, bad breath, vomiting, diarrhea and a bunch of other things. Dogs with end-stage kidney disease have high blood pressure, stop eating and ultimately collapse, go into a coma and even can die. Unfortunately, owners usually don’t detect kidney disease until the damage has become irreversible.
Canine kidney disorders can be classified into those that are chronic and those that are acute.Chronic kidney disorders are caused by long-term insult to the kidneys which, over time, damages their ability to adequately concentrate urine and remove wastes from circulation. As kidney function deteriorates, the dog retains nitrogen, acids, ammonia and other toxic substances in its blood and tissues, causing a condition called uremia. Chronic kidney disease can be caused by trauma, congenital abnormalities
Kidney disease or damage can be caused by a host of factors, including infection, drugs, or other chemical toxins, trauma, advanced age and even congenital kidney conditions. An annual blood screening test can help identify kidney problems as early as possible so that owners and veterinarians can do their best to manage progression of the disease.One of the most troubling aspects of chronic kidney disease is that affected animals usually do not show clinical signs
Kidney disease is fairly common in domestic dogs, particularly as they advance in age. While a number of things can contribute to kidney disease, the symptoms tend to be nonspecific. Early diagnosis and intervention may help curb progressive kidney damage in acute cases. However, especially in chronic cases, one or both kidneys usually are severely and irreparably damaged by the time observable signs appear.The symptoms of kidney disease result from the body’s attempt to compensate
Kidney disorders in dogs can occur for a variety of different reasons, and they can affect dogs in a number of different ways. Kidney diseases tend to be categorized into those that occur acutely and those that are more chronic in nature.Chronic renal disorders, often called chronic renal failure (CRF), results from long-term insult to the kidneys which, over time, damages their ability to adequately concentrate urine and remove nitrogenous wastes from circulation. Chronic kidney
Simple blood and urine tests are available to diagnose most cases of kidney dysfunction. The common blood tests are a complete blood count (CBC) and a serum biochemical profile. Dogs with kidney disease have elevated levels of blood urea nitrogen (BUN), creatinine, phosphorus, potassium and other electrolytes, caused by the kidneys’ progressively deteriorating ability to filter waste products from blood and excrete them in urine.The other main diagnostic tool for renal disease is a urinalysis.
Dogs with acute renal disease normally require hospitalization and prompt administration of intravenous fluids at carefully managed, above-maintenance levels, to restore hydration and promote urination. An indwelling urinary catheter may be inserted so that urine output can be quantified. If necessary, urine production can be enhanced by administration of certain drugs. If electrolyte or acid-base imbalances are present, the attending veterinarian can prescribe supplements to restore normal levels. Other medications are available to relieve abdominal
