I was convinced my Lucy was dying when she was a tiny puppy - it was awful. She was ill after feeding her a can of beef dog food from a well-meaning neighbor.
I took her to the Vet and we determined she had mild liver issues; but she was still showing symptoms the entire week-end. Turns out - she ALSO had bad gas - which she reacted to by hiding, flopping over (seemed like seizures to me), and just acting crazy. I held her on my lap the whole week-end crying. I finally had my cousin come over and sit with her because I was afraid I was making her worse with my demeanor. I got out of the house for a day and knew she was in good hands. AND she was with someone who wasn't convinced she was on death's door.
She came out of it and my son jokes to this day that Lucy had to be rushed to the Vet for gas. I was convinced, though, that she was dying due to her behavior; not eating; not drinking; hiding; lethargic, etc.
OP, I hope that your little pup gets better and I see that you are willing to take whatever steps are necessary. That's good. It sounds like things are going in the right direction - especially if your vet seemed unconcerned.
