I agree that the bile acids are more indicative of MVD, i don't really feel like an ultrasound is the best way to diagnose a liver shunt. Have you done a protien C test? that would be my next step.

You can still have an MVD dog neuterd. Like previous posters stated, just take all the extra precautions. I am having Copper neuterd in about a month and a half and he has MVD. My vet is very optomistic about the surgery. I did have to switch vets with him in the process of diagnosis, to one who had more exp. with liver compromised dogs. I would finish diagnosis before doing surgery and be sure that you are confident in your vet.
