My 2 year old Moodle won't eat, I try her on meat mixed with rice and veggies, meat on its own, chicken wings. She may eat a few bites hand fed but she will go days without eating, I can hear her tummy grumbling. I'm extremely concerned, please help me

How "extremely conserned" are you? Concerned enough to take the dog to a vet? Because really, that's what you should be doing.

I have been to a vet and he disregarded it, will try another vet

If the vet doesn't care, you really should go to a different one.
