did you have pre and post bile acids done? sounds like a shunt as puppy is young and after eating. What is protein amount on dog food? Tough as puppies have to have higher protein but if liver baby needs to be low protein. Once you have bile acids back that will give you a better idea --if post is over 100 then could be a shunt - i am leaning more towards shunt or mvd than epilepsy
when will blood work be back --- Shunts are fixable but the best person is dr tobias at ut and i would only have her do this surgery if it is a shunt.
Liver_Shunt_And_MVD_Support@yahoogroups.com is a group you want to join if it is liver shunt to learn everything you can before further testing. My dee dee is mild mvd and i learned alot about this while trying to figure out what to do with her but she has never showed symptoms of liver disease - just showed up on her blood work. Make sure no rosemary in dog food as that can trigger seizures in dogs as well - hang in there
