My dog suddenly drinks and pees a lot. What causes kidney issues?

Updated On September 23rd, 2025

Pet's info: Dog | Italian Greyhound | Female | spayed | 9 years and 5 months old | 14 lbs

Did an IDEXX, all levels normal except low albumin, low total protein, high amylase, and high BUN. The urinalysis (creatine?) ratio is 5. I was told normal is 1. Did IDEXX same time last year and everything was completely normal. Only symptoms frequent urination and drinking of water. Doing a culture on monday to rule out kidney infection. Any idea what could cause a sudden issue with kidneys? Other blood wastes are normal. Is the outlook treatable or fatal? Clean teeth, healthy dog otherwise.

There are many possible causes but age related kidney failure or interstitial nephritis would be most common in an otherwise well dog. Diet manipulation and monitoring of salts in blood can minimise the progression of disease
