dog vomiting

Question
My chi-ah-ah/ yorkie ablout 12 lbs. has been throwing up white foam for about 12 hrs. I've tried to give him strawberry gatorade, but he's not drinking it, his breath smells, like his stomach is upset and he's listless and sad. Toy is 2 yrs old

Answer
Jackie, Can you bring him to the vet for some blood work?  He may even need an I.V. for fluids.
JUST so many things can be going on here.  I do have suggestions but would rather you see the vet first.  Contact me after you call the VET ..
Good luck
