Q. I have a 1.5 yrs old male Shih Tzu-Terrier mix do. His Urea Nitrogen was 40 and his BUN/Creatinine Ratio was 44. What could be wrong?

Answered By

A. It would helpful to know units of BUN (mmol/l or mg/dl). It looks that your dog suffers from kidney disease. At such a young age kidney malfunction are usually due to genetic problem or intoxication. You should talk to your vet about kidneys scan and treatment options.
