A 6 year old, 15#. small mixed breed dog recently had a urinary obstruction and went to emergency. Liver small on u/s, the stone was ammonium acid urate, liver values normal but resing bile acids was 24.8 (<13 wnl) , post prandial normal.
I'm thinking microvascular shunt. He has a great appetite so not SP deficient. I'm finding that the herbals suggested for urolithiasis or microvascular shunt in your big red book don't seem to fit for him and ammonium stones not noted at all that I could find (I checked your book with Susan Wynn also)
I have not seen him to do a tongue and pulse yet.
I appreciate your recommendations.
