Started up last night. My best guess would be that she ate grass from a lawnmower with oil in it on last night's walk. This grass was in the street btw but it was so dark I couldn't see it and she's FAST! I think she was sick at least 7 times last night and she vomitted the longest, thickest pack of fresh grass I've ever seen. Whenever her stomach is upset she eats grass (to try and sooth it I guess) and is sick. This morning was no better but strangeley enough she was sick 4 hours after I fed her. I called the vet and was told to not give her any food for the next 12 hours and then only sparcely. Anyone else have cows instead of dogs? Any suggestions?
