My dog is regurgitating, shaking and can't fully bend/move his limbs?

I took my Jack Terrier to the vet today (so I'm looking for extra opinions).

Yesterday my Grandmother fed my dog a turkey bone. He didn't eat it all and vomited the rest (actually vomited not just regurgitating). Some hours went by and he started regurgitating bile/yellow thick-ish water. He can't keep down food. He keeps down SOME water.

We took him to the vet. They took ex-rays and didn't see any bones and gave him a anti-nausea injection and sent him home. His symptoms have been very on/off. He walked out to my living room but a few minutes ago he couldn't bend his limbs or his head to drink out of his water bowl and started shaking. (Sometimes when he walks he can't really bend his legs and starts to wobble over until he falls.) He seems to only shake when he tries to exert himself physically. I know these are neurological symptoms, but I have no idea what to do.

Does anyone know what this might be, or if he will survive?
