I'm sorry that you are seeing those numbers...Anesthesia causes some toxic build-up, so millk thistle is highly recommended after surgery to help detoxify.
Odds and Ends Milk Thistle given before and after surgery may also help protect the liver from any effects of anesthesia.
As I mentioned in a previous post, Azodyl is an excellent supplement for dogs with kidney issues because it helps normalize the urea cycle and lower the BUN by helping control the toxic build-up.
Vetoquinol Azodyl Azodyl administered orally on a daily basis has the potential to decrease BUN and creatinine levels...
