Dog vomitting and shaking

[omnivore]

Tonight, abnormally, our 5 mth old jack russel Joey wouldn't go to bed...he normally sleeps quite contently with us and out other jack russel Roxy...he threw up a couple times on our bed and floor, then we put him out...he releived himself, then when we gave him a bowl of water , he drank it all immediately...wanting more, we gave him more...he can't keep it down, and he seems to be shivering....we did manage to calm him enough to get about an hour's sleep, but then he woke us again to be let off of the bed to vomit again.....please help.

i am now also noticing that he seems to have a poor sense of balance or is just clumsy from weakness.

Your dog sounds like he has ingested something that is making me very ill, perhaps some type of poison. He needs vet care as soon as possible.
