The following breeds are prone to chronic renal failure :
– Bull Terrier
– Cairn Terrier

Diagnosis of Kidney Failure in Dogs
Your dog will undergo a complete blood profile, including a chemical blood profile, a complete blood count, and a urinalysis. Dogs with chronic renal failure may have anemia, abnormal electrolyte levels, and elevated blood pressure. The levels of certain protein enzymes and chemicals such as creatinine and blood urea nitrogen (BUN) will also be high.
Another good indicator of chronic renal failure is urine that is either concentrated or dilute, thus indicating the kidney’s inability to process the urine correctly. X-ray or ultrasound imaging may also be used to observe the size and shape of the dog’s kidney(s) to see if there are any visibly noticeable abnormalities. Often, chronic renal failure causes kidneys to become abnormally small.
