I'm so sorry to hear about your dog. I would definitely join this group:
Liver_Shunt_And_MVD_Support : Liver Shunt & MVD/HMD Support
My Teddi had LS surgery 1 year ago. She had absolutely NO symptoms for one year and then I came home one day and found her drooling and then started our adventure. The people on that group are so knowledgeable and will be your best bet for help with this. Good luck!!
Here is Teddi's story:
