“I decided not to give the antibiotics and immediately took her off of the food. I went back to the natural health food store”
In my opinion, that is where you made a mistake. You listen to anonymous strangers, pet supply store employees and who knows who on the internet instead of a veterinary healthcare professional, a veterinarian that has gone to school for over 8 years (as much as an MD) and has examined hundreds of animals?
Seriously, I would take the pup back to the vet that has examined the dog and is trying to help.
I would do exactly as he recommends, no one else. If no results within a reasonable time, consider consulting a internal medicine veterinary specialist.
Good luck.
