Hi! I hope your baby is going to be ok. Unfortunatly the pet insurance won't help if your dog has a liver shunt as this is not covered on insurance. My Teddi had a liver shunt and the insurance did not cover one dime of it. I would join this yahoo group:
Liver_Shunt_And_MVD_Support : Liver Shunt & MVD/HMD Support
the people on there are so knowledgeable. This group is a great resource and helped me a lot with Teddi.
