I agree about the vet check, be sure ask for a complete thyroid antibody panel to be done.
If the vet cannot find anything medically wrong, then something is being missed. Dogs (IME) do not suddenly and drastically regress and act the way your dog is for no reason, so I can't see how going back to square one can possibly help reverse these serious issues, unless you know the cause of it and address that.
I am so sorry this must be very distressing for you.
