here is a schnauzer with vestibular and i know the vet said no but i keep going back to this as it looks like your dog
more than the liver shunt videos and she is not affected by eating. My guess is she has mild liver disease like mvd and her bile acids were slightly high but we will see as my vet said my dd had liver shunt and to have scintigraphy etc and everything and her bile acids were below 100 with no symptoms so sometimes they are trying to find answers so badly the throw it out there and keep running tests to figure it out. If those biles are not over 100 this is not liver related it is neurological - also i think someone posted that 2 days on lactulose if it is liver shunt related the symptoms should subside. Have you seen any of it subside at all since giving the lactulose?
