Going through something quite similar with my dog. Back & forth to the vet. Blood tests were inconclusive, and may have to be done again. I am fortunate that I have a vet friend who lives miles away, and emailed him the lab reports along with details of any medication prescribed. He assured me my vet was doing everything he possibly could, and NOT to change vets.
I'm lucky I have her insured so only pay a percentage. The blood tests may give you some answers hopefully.
My dad spent 40 years mastering his craft, and last week someone half his age told him how to eat.😠
too, Bluebelle!
