Hi. Sorry to hear you are having problems with your pup. This is info I found on the web: Kidney failure occurs due to poisonings (antifreeze, ethylene glycol), changes in blood flow to the kidney (renal ischemia), obstructions to urine flow, infections, congenital defects and for no apparent reason.

My dog's liver shunt wasn't diagnosed until after she was spayed. She didn't handle the anesthesia well and futher testing was required. She was around 2 years old and showed no symptoms. Tests showed that she was very sick, but you'd never know it by the way she acted. Now she's being medically managed, liver protecting/regenerating meds and blood tests.

Hope this helps and I wish you the very best on your puppy's road to recovery.
