I gave my dog left over spanish rice two nights ago and shortly thereafter she threw up. Then she did not eat any other food. Last night, she woke me up around 4am feeling sick and ready to throw up and by 5am actually did all over my bathroom floor. What she vomited was grass and bile,

with some wood chips from the mulch my daughter just put on the yard. We tried to put aloe in her water but she did not drink it so we threw it away and gave her pure water. She has not eaten at all and I see her lethargic and hungry but not too hungry. She will eat a mouthful of her dog food and then shy away. What can I give her so she does not throw up and sleeps restfully?
