Sounds like what I'm going through with my baby
I got a lot of great advice here from the other YT members. Don't bother going to a vet, that was my mistake and I spent a lot of money there already when they didn't really do as much as they could of in my opinion. My dog had a lack of appetite, couldn't walk (or in other words walked like she was drunk, stumbled), screamed, but had normal sugar levels as well and they also said my puppy would be fine. My puppy is now in the pet hospital emergency room and is going to see a neurologist/specialist today. The doctor in the ER said it is possible that she may have a liver shunt, but there are still other possibilities of what it may be, but we won't know for sure until later tonight. So best of luck to you, hope your Molly feels better!
