Q. My dog has been sick going on 3 days, he wont eat hes very weak and hes vomiting up water like and green stuff. Hes never had any of his shots before
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. I'm very worried about your dog. 3 days of vomiting has likely seriously depleted his electrolytes, and at this point I'd guess he's severely dehydrated. Without any vaccinations my first suspicion would be parvo virus, a highly contagious GI virus of dogs, but many other things could be going on if that's not it. The bottom line is that he needs to get treated right away, and figure out what's going on with him so that he can get better. Please take him in for care ASAP.
