The kidneys perform the essential function of removing waste products from the blood and regulating the water fluid levels

When kidneys don't function properly, toxins build up in the blood and a dog will become ill. 

Any condition which damages the kidneys is referred to as kidney or renal disease. In some cases, dogs may show early warning signs of kidney disease.

However, signs of serious illness only appear after 75 percent of the kidneys' function has already been lost. This is the reason why early detection is so important, especially for dogs age 7 or older. It's very important to have blood and urine tests to detect kidney failure.

Dogs suffers from kidney failure if it remains dehydrated despite more fluid intake, has poor appetite, steadily loses weight, and little energy in moving around. 

He sleeps most of the day and night with only brief periods of wakefulness while vomiting frequently and cannot keep the food down. 

Symptoms also include elevated blood pressure, uncontrolled urination, breathing abnormally, and faster heart rate.

Kidney disease is common in dogs, but with early diagnosis and treatment, progression can be limited and many dogs go on to live happily for years after diagnosis.  

Kidney transplants are available for dogs and cats at several veterinary hospitals.

With treatment, pets with CRF may live months to years. It will all depend on how the body responds to the treatment.
